Developing a GNSS Position and Timing Authentication Testbed

FIGURE 1: Characterization of interference from the user perspective

Increasing demand for ensuring the authenticity of satellite signals and position/velocity/time (PVT) calculations raises the need for tools capable of assessing and testing innovative solutions for verifying GNSS signals and PVT. Today’s civilian systems do not provide authentication at the system level, and a number of mitigation strategies have been developed in the last 10 years at user segment in order to protect receivers from interference and deception.

Civil Galileo System Poses New Options for Secure Services

Conceptual design of ULTRA (ultra low-cost PRS receiver)

When European leaders first took up the idea of creating their own GNSS system nearly 20 years ago, they held up the concept of civilian control as a crucial differentiator from existing services operated by national military establishments.

As Galileo nears its operational phase, that principle may manifest itself in a surprising form: the opportunity to offer a range of security-oriented positioning and timing solutions in place of the all-or-nothing alternatives on encrypted services maintained by defense agencies.

Taking Turns at the Fiscal Cliff

Taking Turns at the Fiscal Cliff

The GPS program has taken a fiscal hit that will delay critical plans to begin multi-satellite launches and could ultimately hamper the Air Force’s ability to keep the constellation at its current level of service.

The shortfall is just one of the challenges facing the program over the next four months as the current six-month budget extension winds down, the government’s ability to borrow runs out, and, barring a fast political deal, the onerous budget cuts set up under sequestration kick in.

They’re Back: LightSquared Tries New Route to Wireless Broadband, Later for Nearby GPS Band

They’re Back: LightSquared Tries New Route to Wireless Broadband, Later for Nearby GPS Band

With the election finally over, and the chain of decision makers now largely clear, the spectrum war between LightSquared and the GPS community is heating up again with new fronts opening at the Federal Communications Commission (FCC) and Congress.

The focus of the action are changes to rules governing spectrum and receivers that, if enacted, could enable LightSquared to move forward with its plans for a high-powered, terrestrial broadband network.

Galileo Round Up

Galileo Round Up

Say what you want about the European capitol — one thing is for sure, Brussels is alive with conversation. With corporate high flyers and political decision makers tripping over one another on their way to long lunch breaks and after-dinner drinks, the chitchat can flow fast and furious.

If one is not careful, idle conversation can turn into rumor and rumor become a “buzz.”
