  • Missing Plane, New Mapping Abilities, and GPS Jamming

    As the tragedy of Malaysia Airlines Flight 370 riveted our attention, many sprang into action. More than two million volunteers scoured online satellite images for signs of the plane via Tomnod, a crowdsourcing project of DigitalGlobe.

    Volunteers like Robert Wilkinson are asked to view satellite photos and tag any signs of wreckage, rafts, oil spills and other objects that may be of interest. “It took me the first hour to understand that I was looking at waves or tidal pools rather than debris or anything useful to the search,” said Wilkinson. “After that, I might have seen one or two things that I couldn’t explain, but I tagged them appropriately.”

    All images that are tagged are reviewed by special algorithms before being viewed by experts. Tomnod reported that more than 650,000 objects had been tagged, and the maps had been viewed more than 98 million times.

    Calls on Flight 370. This month, the Internet was full of questions about mobile communications and the missing Malaysia airplane. People didn’t understand why passengers on board the flight hadn’t made mobile emergency calls. On September 11, 2001, it was widely recalled, some passengers were able to make phone calls from the hijacked planes. Flight 370 was likely too high or going too fast to enable phones to register with cell towers. Experts say that planes flying above 5-10,000 feet would have difficulty making connections. Radar analysis estimated that the plane may have been flying as low as 12,000 feet or as high as 45,000 feet. On 9/11, passengers made calls when the plane was low or used satellite air phones available in business class.

    GPS and Football. Security at places where large crowds congregate is always a concern. At last month’s Super Bowl, GPS devices tracked and monitored the team vehicles. To protect the GPS, a product from Exelis was used to detect and locate GPS interference sources to protect critical GPS signal-dependent infrastructure. Eight sensors were positioned in an array pattern to detect and locate any jamming sources.

    Lost in Space. Google’s Project Tango is showcasing a prototype phone brimming with software and sensors that creates a 3D map of the environment. A select group of developers has been given the device and are expected to create innovative applications, including navigation by sight. We do know that one of these devices will be heading to the International Space Station and will be part of a project to enable robots to explore the inside and outside of the craft. The terrestrial uses of the device will include being able to map the interior of a house (the sofa goes where?), navigate through complicated buildings, provide accessibility for those with impaired vision, and emergency response. Project Tango may find interesting uses with 3D printing, which is riding a wave of interest.

    GPS and LED Lights. Philips has been demonstrating an indoor location-based shopping service based on location positioning from LED lighting infrastructure. The system works by using lighting fixtures that form a dense network that not only provides light, but also acts as a positioning grid. Each fixture is identifiable and able to communicate its position to an app on a shopper’s smart device. ByteLight is another company with LED indoor location technology. Wi-Fi and Bluetooth low-energy (BLE) beacons are more established for indoor positioning.

    Truck Market on the Move. Market demand remains strong for mobile resource management (MRM) devices, particularly among local fleets, reports C.J. Driscoll & Associates. “Manufacturers of light and heavy commercial vehicles are becoming increasing involved with telematics,” says Clem Driscoll. “Heavy truck manufacturers are primarily focused on enabling remote vehicle diagnostics.” Many of the large MRM companies are establishing added offices around the world.

    Awkward Timing. INRIX is launching Russia’s first comprehensive traffic information and driver services platform. Russia has many challenges including difficult traffic conditions. The service, available on Audi cars, was developed through an exclusive partnership with Russia’s navigation services provider cdcom. INRIX XD Traffic in Russia provides real-time traffic and incident information covering more than 236,000 kilometers of roadways across 55 cities.

  • You Can Help Find Missing Malaysia Airlines Plane

     

    DigitalGlobe, Inc., has launched a crowdsourcing campaign that will allow anyone to help look for the missing Malaysia Airlines flight MH370 by combing through satellite images for clues of its whereabouts.

    The search drew so many participants on its first day March 17, that it crashed the company’s website, with 500,000 visitors wanting to help find the missing Boeing 777. Anyone can begin searching the satellite images, tagging anything that looks suspicious. Each pixel on a computer screen represents half a meter on the ocean’s surface.

    The Longmont, Colorado, company said two of its commercial satellites have already collected images comprising roughly 1,988 square miles at the confluence of the Gulf of Thailand and the South China Sea, where the Beijing-bound aircraft mysteriously went missing on Saturday. The company is continuing to update the images to reflect new information about the search area provided by the Malaysian government.

  • Harris Corp. Completes Space Qualification Testing of Hosted Payload for Global Aircraft Tracking System

    Harris Corporation has achieved a key milestone under a five-year contract with Aireon LLC that will create the first global satellite-based aircraft tracking system. The announcement was made during the SATELLITE 2014 Conference and Exhibition, held March 10-13 at the Washington Convention Center in Washington, D.C.

    The company’s Automatic Dependent Surveillance-Broadcast (ADS-B) 1090 Extended Squitter receiver payload has been successfully tested and qualified for simulated operation in the harsh environment of space for more than 12 years. Simulated performance testing also validated the agility of the payload to adapt to evolving aircraft traffic patterns over the same span of time.

    Harris is providing Aireon with 81 of the ADS-B receiver payloads. They will be hosted on board the Iridium NEXT satellite constellation to enable precise aircraft tracking that will optimize air traffic management around the world. Ground-based ADS-B networks, which process GPS signals and other data from aircraft, are limited by an infrastructure that cannot monitor flights over oceans or remote regions, a limitation now highlighted by the disappearance of a Malaysia Airlines jetliner on March 8.

    The Harris payloads are based on the company’s AppStar reconfigurable payload platform. They will be mounted on 66 low Earth-orbiting satellites, six on-orbit spares and nine ground spares that comprise the Iridium NEXT constellation. The air traffic surveillance function will be performed separately from the main mission of the spacecraft. The constellation’s main mission is providing voice and data coverage to satellite phones, pagers and integrated transceivers over Earth’s entire surface. The launch of the first Iridium NEXT satellite is planned for 2015.

    “Completion of this testing verifies that our payload design works for its intended environment and moves us into the production phase,” said Bill Gattle, vice president and general manager, National Programs, Harris Government Communications Systems. “This program exemplifies the benefits of a public-private partnership model, using commercially hosted payloads to get both government and commercial mission capabilities into space without the time and cost required to build and launch separate satellites.”

    “Harris has met or exceeded all of the major milestones in the development and test of the receiver payload for this groundbreaking program,” said Don Thoma, president and CEO, Aireon. “The combined, powerful offering our collective organizations will provide to the global air traffic community will transform air travel.”
