Navipedia — The GNSS Wiki

Javier Ventura-Traveset introduces Navipedia at the Munich Satellite Navigation Summit on March 14, 2012. He is responsible for managing Navipedia’s development as well as GNSS education activities for ESA.

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.

In the last 30 years, satellite navigation applications have grown in number and kind, entire new systems have emerged, and existing systems have modernized.

The U.S. Naval Observatory Alternate Master Clock at 2nd Space Operations Squadron, Schriever AFB in Colorado. This photo was taken in January, 2006 during the addition of a leap second. The USNO master clocks control GPS timing. They are accurate to within one second every 20 million years (Satellites are so picky! Humans, on the other hand, just want to know if we’re too late for lunch) USAF photo by A1C Jason Ridder.

1. NUMBER 3
Cape Canaveral, Florida USA
√ A third GPS IIF has arrived at Cape Canaveral and is being prepped for an October 4 morning launch. Two of the “follow-on” models with better clocks, trickster-foiling technology and more powerful signals are already up. Numbers four and five are waiting to go.
