FCC Raises Questions about U.S. Access to Non-GPS GNSS

FCC Raises Questions about U.S. Access to Non-GPS GNSS

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.

Why are carrier phase ambiguities integer?

Why are carrier phase ambiguities integer?

It is well known that carrier phase ambiguities are integer values. Intuitively, this is hard to understand with a common counter-argument progressing along these lines: even if the receiver measures the instantaneous phase of the incoming signal (thus removing any fractional cycle component at the receiver end), the phase of the signal at the satellite cannot be guaranteed to be zero, so how can the ambiguity be integer?

In this article we explain why the carrier phase ambiguities are indeed integer.

“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.”

CERGAL 2015: International Symposium on Certification of GNSS Systems and Services

CERGAL 2015: International Symposium on Certification of GNSS Systems and Services

The Waldspirale in Darmstadt

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:
