Really Rocket Science

Rocky Mountain Tracking's device is accurate. So good, in fact, it beat a police radar in court:

Eighteen-year-old Shaun Malone has a few people to thank for being able to plead "Not Guilty" to a speeding offence - his parents, who installed a GPS device in his car, and Rocky Mountain Tracking, the service provider of that device.
 
"Because of our GPS tracking data, Malone and his parents can protest the imposition of an unfair speeding ticket," says Brad Borst, Founder and President of Rocky Mountain Tracking, and who is also a former Police Officer.

A police radar had found Malone driving at 62 mph in a 45-mph zone. However, Malone's parents, who had installed the Rocky Mountain Tracking GPS device in his car to monitor his driving, found that the device tracked him driving at, and not above, the speed limit.

The most telling testament to the accuracy of the Rocky Mountain Tracking Rover GPS tracking device came, ironically, from a GPS expert who originally helped find Malone guilty in a trial-by-affidavit. Dr. Stephen Heppe, the expert, had written a report affirming that, going by the GPS data, Malone had to have been traveling faster than 45 mph.

Read their blog for more detail. And Hot Hardware gets more from the expert:

While the police clocked him going 62-mph, the GPS's data in fact showed him driving at the 45-mph speed limit. In an initial trial-by-affidavit, Malone was found guilty of speeding. GPS expert, Dr. Stephen Heppe wrote a report that essentially said that the GPS data was not accurate enough to contest the accuracy of the radar gun. Malone appealed the decision and had his day in court. At trial, things played out differently:

"However, when he took the stand to begin his testimony, Dr. Heppe corrected that written report, saying that the Rocky Mountain Tracking device was "very" accurate, to within a couple of meters on location and to within 1 mph on speed. Dr. Heppe also pointed out that the GPS device released instantaneous data, and not data averaged over a distance."

Needless to say, with Dr. Heppe's revised testimony, Malone was found innocent of speeding.

Teenagers. Some learn about the danger of speeding the hard way, some know better before they start driving. Check out this kid in Kentucky:

Landon Wilburn, 11, grew tired of speeders zipping through his subdivision, so after growing hoarse shouting at them, he decided to take matters into his own hands.

The youngster, who used to shout at speeders to slow down as they drove through the Stone Lakes subdivision in Louisville, now has taken matters into his own hands.

Dressed in a reflective vest, wearing a bicycle helmet and armed with an orange Hot Wheels brand radar gun, he points and records the actual speed of passing traffic.

Landon also carries a flashlight with a built-in siren.

"When I saw it happening, I got the biggest kick out of it," said resident George Ayers, 61. "People were locking up their brakes when they saw him."

You can hack these toy radar guns, or you could really have some fun as-is.

It's officially summer, and I'm feeling a bit nostaligic.

Like many kids who grew up in the suburbs, my memories are filled with ice-cream trucks, slip-and-slides, and…oh yeah…petty crime. Before images of vandalism start running through your mind, let me explain. My misdemeanors were of a more innocuous variety, namely pool-hopping:

pool hopping
Hoping from pool to pool; usually done at night, or during the day when people (pool owners) are working. It is the act of running to one neighbours pool jumping in, then running to another pool to jump in,, and continue the cycle.This is all done without getting caught(hopefully).

We all knew which houses in the neighborhood had the best pools, and, after some fence-scaling and other secret-agent-worthy tactics, we'd be cannon-balling into the deep end.

But these days the childhood pasttime is going high-tech. Groups of kids are using Google Earth to find pools and organizing their outings on Facebook.

Call me old-fashioned, but I agree with this guy. Between creating facebook groups and dodging motion detectors, all the technology has taken the fun out of it.

Yesterday at 4:12 pm at Cape Canaveral, an Atlas 5 rocket successfully lifted ICO Global Communications' ICO G1 North American geosynchronous satellite, "a mobile communications satellite to assist and entertain Americans on the go."

The launch marked the first commercial flight in two years of an Atlast 5, and the carrying of its heaviest payload ever: 

 Weighing 14,625 pounds, the ICO G1 spacecraft was the heftiest payload ever launched by an Atlas rocket. Built by Space Systems/Loral, the craft stands over 27 feet tall, features a 39-foot-diameter mesh reflector antenna that will be unfurled in space and a pair of power-generating solar wings to span over 100 feet tip-to-tip once extended in orbit.

It's a pretty bird, the G1:

 The ICO G 1 satellite belongs to the 2-GHz mobile systems, which are driving a growing segment of today's satellite manufacturing industry.

ICO's G 1 satellite is based on SS/L's space-proven LS-1300 platform, which has an excellent record of reliable operation. Its high efficiency solar arrays and lightweight batteries are designed to provide uninterrupted electrical power. In all, SS/L satellites have amassed almost 1,200 years of reliable on-orbit service.

ICO G1 is a next-generation satellite designed to deliver a wide variety of interactive services to mobile and portable devices using ICO's Mobile Interactive Media (ICO mim™).

The launch marks the first deployment of DVB-SH service in North America. DVB-SH is short for Digital Video Broadcasting - Satellite services to Handhelds; it's "a physical layer standard for delivering IP based media content and data to handheld terminals such as mobile phones or PDAs, based on a hybrid satellite/terrestrial downlink."

ICO mim addresses a wide variety of consumers' entertainment, information and two-way communication needs, including live and stored mobile TV in vehicles, interactive navigation, and roadside assistance, all with nationwide coverage.

ICO mim will also initially provide 10-15 channels of premium television content to portable, larger-screen (4.5- to 10-inch) user devices. Initial partners for the trial phase of ICO mim include Alcatel-Lucent.

Very interesting news from California this morning about Space Systems/Loral and Northrop Grumman's Space Technology division getting together to go after U.S. government business. Building spacecraft for fully-funded government projects can be more profitable than going after commercial projects. Sounds like a simple agreement:

"The agreement with Northrop Grumman will allow SS/L to cost-effectively add capacity to address increased near-term commercial satellite opportunities," said Pat DeWitt, chief executive officer, Space Systems/Loral. "The agreement will also streamline the process for our companies to collaborate on providing the world's best satellites for both civil and defense applications."

"The resulting strategic agreement will be important to increasing our competitiveness. These initiatives will present win-win opportunities for both companies and our U.S. government customers," said Alexis Livanos, corporate vice president and president of the company's Space Technology sector. "For some of our mission areas, we believe that assured access to SS/L's 1300 bus and bus subsystems would improve our cost and delivery schedule competitiveness. In addition, hosted payloads hold the promise of providing us greater ability and flexibility to rapidly respond to our government customers' evolving needs."

Some of these new opportunities included "hosted payloads" where specialized instruments or entire subsystems can be added on to a satellite bus whose primary mission is paying most of the build cost. Given the importance of the role space plays in today's C4ISR systems (Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance), and the expected ends-of-life of the spacecraft currently in orbit, we'll need a bunch of new launches in the short term. Factor in programs being behind schedule -- with some going way over budget --  and you might conclude we have a problem, Houston. Intelsat General is going after this market, too.

Northrop Grumman is involved in a new moon mission for NASA, the LCROSS (Lunar CRater Observation and Sensing Satellite):

GPS systems appear to be the newest must-have gadget. They were flying off the shelves in December:

Personal navigation devices are a hot gift to give this holiday season. Unit sales of GPS systems rose 488% over last year, according to the latest point-of-sale information from market research firm NPD Group.

And GPS providers are not planning to sit on this past year's successes. Forbes.com list GPS chipsets as one of five "emerging technologies" of 2008:

GPS chipset provider, SiRF Technology Holdings is the company to beat in the personal navigation device space, with over 50% market share. The company is one of several gearing to battle it out for a piece of the next-generation cellular handset market.

Mobile phones are only starting to emerge as a high-growth market for GPS chipsets, which include the basic radio-frequency (RF) and GPS base-band chips. True, most handsets already incorporate the technology, but it goes largely unused because most network operators have been slow to roll out location-based services with broad consumer appeal.

The other reason GPS chipset suppliers have ignored the current generation of mobile handsets is Qualcomm, which has been packaging GPS capability into its mobile phone chips for the last seven years. The industry, however, is shifting from today's global system for mobile communications and CDMA network standards toward 3G, or W-CDMA standards, and next generation-compatible handsets are forecast to see a compound annual growth rate of 22% over the next five years.

But you don't need to wait for the market to marry GPS and cell-phone handsets. Turn your cell-phone into a GPS tracking device:

DIY GPS tracking with "disposable" phones - Mod a GPS enabled Nextel and fauxjack yourself...or your car, or your kid, or a big dog, or an elephant. We really, really want to track an elephant. Mologogo is a free service that will track a "friends" GPS enabled cell phone from another phone(gps not required) or on the web. It currently works on pretty much any Nextel phone with Java and GPS - even a $60 no-contract Boost Mobile phone.

Using any GPS-enabled phone with java and a supported provider (Nextel, Sprint, or Boost), you can install a free service called Mologogo and turn your phone into a tracking device.

What can Mologogo do?

From your phone or the web, Mologogo shows you where you and your friends are at any moment. If you are on the go, Mologogo can alert you when friends are close, search around for points of interest, and keep you updated with local traffic and weather. Mologogo even supports mobile chat, so you can reach out to your nearby friends instantly. If you are on your PC, you can see all of your friends - locations, sign up new friends, bookmark locations, and show your Mologogo location on your own web page or blog.

You control who can see your location – anything from the entire Mologogo community to a few select friends. The applications for this are endless: track your kid; use an old phone and a prepaid data plan to track your car or a package; see where friends are in a city; or track mobile employees. (I'm smelling a good marketing opportunity for a quick-delivery pizza chain.)

If you don't have a Mologogo-capable phone, you can buy one for $80 bucks, maybe less. And, unlike some stand-alone commercial tracking solutions, the service is free (as long as your cell-phone has a data plan).

And the locator works very, very fast, as one MAKE commenter explains:

As for the phones: The reason you get GPS lock so quickly (which might make you think it's fake) is that the tower gives the phone a breath-of-life packet, containing the current satellite almanac and possibly even the position of the PRN sequences, so the GPS chip can achieve lock almost instantly.

You can test this by taking the phone to an area with no Nextel towers (Montana and Mississippi work well) and telling it to acquire a GPS fix. It'll take much longer (30-50 seconds typically), just like your Garmin, because it's not getting help from a tower. But even in the complete absence of towers and service, the phone's GPS chip does work just fine, and will happily feed NMEA 0183 data over the serial cable for your laptop's mapping software.

Gorgeous day at the Cape last week, punctuated by a spectacular Delta launch for the USAF by the United Launch Alliance:

United Launch Alliance successfully launched a Delta II expendable launch vehicle today from Space Launch Complex 17-A at 3:04 p.m., EST carrying the Air Force’s GPS IIR-18(M) satellite. This launch marks the fifth mission for the Air Force this year and the 13th and final mission for ULA in 2007.

Following a nominal 1 hour and 8 minute flight, the rocket deployed the GPS IIR-18(M) spacecraft, the fifth modernized NAVSTAR Global Positioning System Block II R-M military navigation satellite. GPS is a space-based radio-positioning system nominally consisting of a minimum of 24-satellite constellation that provides navigation and timing information to military and civilian users worldwide.

"With the launch of GPS IIR-18(M), ULA completes a tremendously successful first year of operation and demonstrates its commitment to 100 percent mission success," said Mark Wilkins, vice president of Delta Programs. "As we continue to provide safe, cost-effective, reliable access to space, we are privileged to serve an important role in critical missions, such as GPS, which are force multipliers for our men and women in uniform serving our country throughout the world."

Designed to operate for 10 years, GPS satellites orbit the Earth every 12 hours, emitting continuous navigation signals. With the proper equipment, users can receive these signals to calculate time, location and velocity. In addition to its military use, GPS satellites provide directional assistance to civilian users around the world.

The ULA Delta II 7925-9.5 configuration vehicle featured an ULA first stage booster powered by a Pratt & Whitney Rocketdyne RS-27A main engine and nine Alliant Techsystems (ATK) strap-on solid rocket motors. An Aerojet AJ10-118K engine powered the second stage. A spin-stabilized Star-48B solid-rocket motor built by ATK boosted the third stage. The payload was encased by a 9.5-foot-diameter metallic payload fairing.

ULA began processing the Delta II launch vehicle in Decatur, Ala., nearly two years ago. In August 2007, the first stage arrived at Cape Canaveral Air Force Station from Decatur, followed by the second stage Sept. 19. The vehicle was erected on the stand at Pad 17-A, Nov. 5, with solid rocket motor installation completed by mid-November. Hundreds of ULA technicians, engineers and management worked to prepare the vehicle for the GPS IIR-18(M) mission.

Wow, now I know. Thanks to a new "killer app" from Google called My Location. The folks at AppleInsider see it:

New Google Maps feature could simulate GPS on iPhones

By Slash Lane

A new version of Google Maps introduced this week includes a beta feature dubbed My Location that was designed to simulate the GPS experience on mobile phones and handheld devices that do not include GPS hardware, like Apple's iPhone.

Essentially, the My Location feature takes information broadcast from mobile towers near non-GPS equipped mobile phones to approximate the device's current location on the map down to about 10 city blocks.

"It's not GPS, but it comes pretty close (approximately 1000m close, on average)," the Mountain View, Calif.-based search giant explained on its website. "We're still in beta, but we're excited to launch this feature and are constantly working to improve our coverage and accuracy."

The My Location feature is currently available for most web-enabled mobile phones, including Java, BlackBerry, Windows Mobile, and Nokia/Symbian devices. However, it is not yet compatible with Apple's iPhone.

Still, Apple has promised to continuously update and improve upon the feature set of its inaugural mobile handset, making it more than likely that the feature will turn up once it emerges from the beta stage.

For a more detailed explanation of My Location and a visual demonstration, please see the video below.

Just downloaded it on a BlackBerry and it works. Amazing.

When we blogged about the Vanco Arctic Survey—a detailed survey about the health of the North Pole cap in a climate of rapid melting—we had no idea that we're in the middle of the International Polar Year. In that spirit, let's head south and check-in on Antarctica:

The Landsat Image Mosaic of Antarctica (LIMA) brings "the coldest continent on Earth alive in greater detail than ever before through [a] virtually cloudless, seamless, and high resolution satellite view of Antarctica." According to NASA, by piecing together more than a thousand images from three years of Landsat satellite observations, the new map provides a realistic look at the continent in 10 times greater detail than ever before and offers the most geographically accurate, true-color, and high-resolution views of the continent possible." NASA is so excited that they argue the map will "revolutionize research of the continent's frozen landscape."

These four frames show the evolution from the old imagery (MODIS) to the new (LIMA):

You can view the interactive image here.

Pan to view the continent and zoom in to see the stunning detail of this Natural-Color, Pan-Sharpened LIMA (bands 3, 2, 1). LIMA covers the entire continent except from the South Pole at 90 degrees south to 82.5 degrees south latitude, where Landsat has no coverage because of its near-polar orbit. To provide a continental view, the image above has LIMA 3, 2, 1 overlaying the MODIS Mosaic of Antarctica (MOA).

The opening view includes McMurdo Station, the largest research base in Antarctica. Located at the tip of Hut Point Peninsula on Ross Island, McMurdo has been continually operated by the United States of America since 1956. Ross Island is roughly 45 miles across. The flat, white areas are the Ross Ice Shelf and other sea ice off the coast of Antarctica. Also visible are the Erebus Glacier Tongue, Koettlitz and Ferrar Glaciers, and the Royal Society Range.

"Qualcomm has won a federal contract to provide a satellite-based tracking system for U.S. and Mexican trucks participating in a contentious experiment that opens the border to long-haul commercial traffic," SignOn San Diego reports:

Federal officials said yesterday that the San Diego-based company's OmniTRACS system will allow the U.S. government to closely monitor trucks from both countries, including compliance with regulations that prohibit truckers from driving more than 11 hours per day.

Although Qualcomm is best-known for its prominent role as a chip-maker in the wireless industry, the company also is a major designer of satellite tracking systems for vehicles.

Qualcomm will provide tracking technology for 100 trucks at a cost of $367,000, officials said.

U.S. transportation officials hope the tracking system will soften congressional opposition to the two-month-old pilot project. Five carriers from Mexico and three from the United States are participating in the program, which is limited to a maximum of 100 carriers from each country.

OmniTRACS uses geosynchronous satellites and "helps fleets improve productivity, reduce operating costs, enhance customer service, and increase security." Features include:

    * Automatic satellite vehicle positioning
    * Two-way text and data communications
    * Highly reliable message delivery
    * Customizable reports
    * AS/400, Windows®, or web-hosted operation
    * Panic Buttons (available option) 

We're not sure what the Panic Button achieves, but we assume it won't be ignored like the car alarms that bleet plaintively in our local mall parking lot. 

Qualcomm has a nice flash demo of OmniTracks here. The system predates commercial use of GPS, and its next iteration -- OmniVision -- will provide real-time directions and maps using Maptuit’s NaviGo to truckers on the move:

Maptuit NaviGo is a real-time, hybrid  in-cab navigation service that provides professional truck drivers and trucking companies with interactive maps for increased routing efficiency and improved driver satisfaction.  QUALCOMM plans to offer NaviGo on the OmniVision platform later this year....

The OmniVision mobile computing platform is an integrated system consisting of hardware, software and network infrastructure, enabling delivery of two-way data communications and value-added services to enterprises in a mobile environment.

I love the smell of hydrochloric acid in the morning! That's what you get when you mix rocket fuel burn-off with the air around the launch pad.

All launches from the Cape are supported by the 45th Space Wing, Patrick Air Force Base -- and people like Chris Bruce, who was featured in nice piece by Patrick Peterson in Florida Today:

When Chris Bruce isn't keeping his 19-year-old daughter's car running, he's using his considerable mechanical ability to lead the team of technicians preparing the third stage of Delta 2 rockets for launch.

The GPS IIR-17 launch from Complex 17A on Wednesday morning will be the latest of nearly 50 rockets on which the 45-year-old Mims resident has worked.

Weighing 4,540 pounds, the satellite will be the fourth to feature newer GPS technology. It will be able to provide more accurate navigation data for pilots, drivers, boaters, hikers and the military.

Working conditions are tough. The good-natured
ribbing between his colleagues at United Launch Alliance, who also are his golfing buddies, often rises to a level of nastiness that only the thick-skinned and steel-nerved can bear.

There is one consolation.

"What goes around comes around," he said, showing a good-natured grin. "What you've dished out the day before, you're receiving the next day."

The constant needling and trading of verbal jabs keeps the crew on their toes, he added. Oddly, it also makes for a good work environment.

"We're like a second family," he said. "It's like hanging out with your brothers."

Long hours at work are required during crunch times, and Bruce's boss depends on him to make sure people and parts are where they should be.

"He leads with his experience," said Robin Smith, an assembly and test manager with 37 years of aerospace experience. "And I do count on him and rely on him a lot."

Bruce's easygoing personality makes him a good co-worker.

"He's very good natured," Smith said.

Bruce is among about 4,000 United Launch Alliance employees who launch government satellites for the company formed by a merger of the rocket divisions of Lockheed Martin Corp. and The Boeing Co. in May 2005.

His crew assembles the launcher's third stage, which is about six feet tall and will push the GPS satellite to its final orbit about 11,000 miles above Earth. The spacecraft will become one of 30 GPS satellites in orbit.

"We've been really good about putting them right where they need to be," Bruce said.

Bruce came to Brevard County 22 years ago, after completing a two-year associate's degree in electronics at DeVry University in Atlanta.

"I had an uncle who worked for McDonnell Douglas. He got me an interview, and the rest is history," he said.

After several job changes, including working as a roofer for a year during a slowdown, Bruce started working on the Delta program in 1996.

If successful, this GPS launch would be the 77th Delta launch since the last failure in 1997. Consistency has been a hallmark of the program.

"There have been very few changes since I've been in this group," Bruce said. "It's basic, but it's efficient."

Bruce said the experienced crew is comfortable processing the rocket's third stage because they have done the job many times before.

"It's just like clockwork," he said. "Everything gets bolted and torqued. We've done it so much, we just know."

Bruce said attention to detail and the determination to do a good job are the personality traits that make his group successful.

"It was the way I was brought up," he said. "My dad always had the philosophy, 'If you're going to do it, do it right the first time. Put forth your best effort.' "

"It's the whole group. It has to be right," he said. "There's no room for error."

During Wednesday's launch, Bruce will follow the countdown even though he doesn't work with the launch crew.

"I really don't worry," he said. "I know the system is reliable and it always has been."
