Global Navigation Satellite Systems Engineering, Policy, and Design
A decade has passed since the first GNSS system-level authentication protocols were proposed, and yet the current ongoing discussion is still, “Do we really need GNSS signal authentication?” Indeed, the current argument is whether we need authentication at the system level (the satellite broadcast service) or whether user-based authentication (anti-spoofing) is sufficient for a number of application requirements.

No reality show contestant ever neared the finish line without the producers serving up another challenge. And so it is for would-be multi-GNSS users in the United States.
After dodging budget cuts, thwarting other teams’ attempts to grab critical frequencies, and dealing with jamming and technical problems, members of the U.S. GNSS community were thrown another curve late last year when they learned that signals from GLONASS and other international constellations must be authorized for use in the United States.

SIDEBAR: Frank van Diggelen’s Compass Points
“It all traces back to my parents,” says Frank van Diggelen. “My father, Tromp van Diggelen, was a surfer. He taught me to surf and swim, in that order, when I was five. I was racing sailboats before I was 10, and there’s a lot of navigation there. Even when you’re just on a lake, the racing is all about reading the wind, understanding angles of convergence, velocity-made-good, and so on.”

The 2015 CERGAL conference will be held in Darmstadt, Germany on July 7 and 8, 2015.
Qualification and certification of mission and safety critical applications are major milestones in the successful operational rollout of Satellite Navigation systems like GPS/EGNOS, Galileo, GLONASS and Beidou. This symposium will concentrate on measures already established and future activities that will assure SATNAV systems certification and operational safety.
This year’s main topics include:

A new study is underway to estimate the economic benefit of GPS and quantify what’s at stake if anything interferes with its navigation signals.
Launched at the request of the National Executive Committee (ExCom) for Space-Based Positioning, Navigation, and Timing (PNT), the first segment of the two-part study would look at major uses of GPS. It will estimate the benefits derived from the system and describe the costs that would be incurred if GPS became unavailable, compiling the results in an interim report.

New competitive demands and regulatory requirements are driving financial firms around the world to use highly precise timestamps on incoming information and transactions, a trend likely to push firms to adopt a common time source like GPS.
