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.

House, Defense Department Move to Bridge GPS Modernization Funding Gap

House, Defense Department Move to Bridge GPS Modernization Funding Gap

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.

SIDEBAR: Flight Control and Target Identification Requirements and Results with EGNOS and Multi-Constellation GNSS

Return to main article: "Drones to the Rescue!"

Following a route defined by application requirements and remotely sensing the environment in order to analyze and interpret the outcome on- and off-line: this is the axioma of every aerial remote-sensing mission and, indeed, also for search missions. Yet, the specific requirements for navigation might vary according to the application.

UAVs Vulnerable to Civil GPS Spoofing

UAVs Vulnerable to Civil GPS Spoofing

In June a research team from the University of Texas at Austin (UT-Austin) demonstrated for the first time that a civilian unmanned aerial vehicle (UAV) can be commandeered in mid-flight by a civil GPS spoofing attack. The result will likely factor into the Federal Aviation Administration’s (FAA’s) plans to draw up rules for integrating UAVs into U.S. airspace by 2015.

Single- versus Dual-Frequency Precise Point Positioning

Single- versus Dual-Frequency Precise Point Positioning

Q: What are the tradeoffs between using L1-only and L1+L2 for PPP?

A: Precise point positioning (PPP) is a technique that can compute positions with a high accuracy anywhere on the globe using a single GNSS receiver. It relies on highly accurate satellite position and clock data that can be downloaded from the International GNSS Service (IGS) or obtained in real-time from a number of service providers, using either the Internet or satellite links.

INS Face Off

INS Face Off

The automobile versus the horse and buggy. Cloud computing opposite desktop software. The trend is predictable, yet it is always surprising when one technology takes over the market space of another. After all, television did kill off the radio star.

Drones to the Rescue!

Drones to the Rescue!

August 1994, early morning. Spain’s Central Pyrenees Mountains still in darkness.

At the outset of an ascent to a 3,000-meter peak along the international border, one of the co-authors encounters a group of tourist hikers who have begun searching for a colleague who had left the camp the previous evening. In the pre-sunrise gloom, helicopters cannot yet operate.

A week later, the body of the hiker is found. The rescue efforts came, unfortunately, too late.

Mission Accomplished: ESA Turns Out the Lights on GIOVE-A

With the first two Galileo in-orbit validation (IOV) spacecraft working well, the European Space Agency (ESA) has decided to end the mission of its pioneering GIOVE-A satellite that had long exceeded it original purpose and design life.

Meanwhile, with the next Galileo launch approaching, ESA has expanded its Radio Navigation Laboratory (RNL) to meet the testing needs of Europe’s GNSS program.

House and Senate Slash Civil GPS Funding

[Updated July 2] Appropriators in both the U.S. House and Senate have slashed next year’s funding for support of the civil portion of the GPS program. Lawmakers halved the portion of the Federal Aviation Administration budget dedicated to supporting the civil signals as well as the ground network monitoring of those signals.
