It’s Back: GNSS and the Right to Privacy

A new U.S. appellate court decision could bring the issue of warrantless tracking of suspects using GPS and other positioning data derived from mobile phones back before the Supreme Court.

And if the case — United States of America v. Melvin Skinner — is appealed to and accepted for review by the “Supremes,” they would probably have an opportunity to more directly address the question of whether U.S. citizens have a “reasonable expectation of privacy” in their personal location information garnered surreptitiously from GPS-enabled cell phones by police.

L-3 Interstate Electronics Demonstrates of New TruTrak Evolution Type II SAASM GPS Receiver at AUVSI

L-3 Interstate Electronics Corporation (IEC) will conduct an operational demonstration of its new TruTrak Evolution (TTE) Type II Selective Availability Anti-Spoofing Module (SAASM) GPS receiver at AUVSI’s Unmanned Systems North America 2012 conference taking place this week (August 6–9, 2012) in Las Vegas, Nevada.

The demonstration will highlight the new TruTrak receiver’s multi-use capabilities as a high-performing Ground-Based GPS Receiver Applications Module (GB-GRAM) for use on UAS platforms and precision weapons.

Trimble introduced its AP20-C, the latest addition to its AP Series of embedded GNSS-inertial OEM boards, at AUVSI’s Unmanned Systems North America 2012 Conference and Exhibition today (August 7, 2012).

Incorporating a compact, custom-built inertial measurement unit (IMU) based on commercial micro-electromechanical mechnical system (MEMS) sensors, the AP20-C enables system integrators to achieve high-rate position and orientation measurements with exceptional accuracy, according to the company.

UAVs: Homeland Security Under Pressure to Take a Greater Role in GPS Anti-Spoofing

UAVs: Homeland Security Under Pressure to Take a Greater Role in GPS Anti-Spoofing

A congressional committee overseeing activities at the Department of Homeland Security (DHS) appears poised to push the agency into a more substantive role in overseeing the use of drones in the United States — a move that could force DHS to move more forcefully to protect GPS users from spoofing.

The Subcommittee on Oversight, Investigation and Management within the House Homeland Security Committee is looking to DHS to manage the civil use of unmanned aerial vehicles (UAVs) or drones.

Both Congress and the Pentagon are putting money on the table to bridge the gap created by delays in the development of the new GPS ground system.

As Inside GNSS first reported earlier this year the Next Generation Operational Control System, or OCX, is running roughly two years behind schedule. It had been expected to be delivered in 2015, however, General William L. Shelton, the commander of Air Force Space Command, said this spring that OCX would be delayed until 2016 or 2017.

Interference & Jamming

Phil Ward, Navward GPS Consulting

The threats just keep growing to a resource that hundreds of millions of people around the world have come to rely on for a myriad purposes.

GNSS is, after all, an RF technology, vulnerable in its own way to the kind of disruptive effects that turn an AM radio into a static-ridden howl as you drive under a powerline. And the radiated energy of signals arriving with from satellite sources tens of thousands of miles away are orders of magnitude weaker than those carrying the top 40 tunes broadcast by a local station.

Brussels View: Remembrance of Things Past

In 2003, China committed to investing €200 million (US$270 million) for the privilege of participating in the development of Europe’s Galileo program. But by 2007 it had been forced out of major decision-making because of security concerns and the collapse of the original financing plan for the program, which was to include public and private money.

Election Politics May Stall Final LightSquared Decision

Election Politics May Stall Final LightSquared Decision

Tim Farrar, TMF Associates

While members of the GPS community are pushing to formally end the threat of signal interference from LightSquared’s proposed wireless network, the political realities of an election year suggest they will have to wait for a decision.

“There are not a lot of reasons to rush,” said Tim Farrar of TMF Associates, a consulting firm that closely follows mobile communications industry, adding it was “unlikely” there would be any progress ahead of the vote in November.

The first two Galileo in-orbit validation (IOV) satellites in space have achieved a new milestone, transmitting dummy signals in a modulation scheme designed to allow full interoperability with GPS once operational services start.

“This is an advanced modulation technique that offers robust protection against signal interference and the misleading signal reflections known as ‘multipath’,” said Marco Falcone, Head of Galileo System Services.
