Global Navigation Satellite Systems Engineering, Policy, and Design
The nation’s leading satellite navigation experts have invited Ligado Networks, a firm whose plans are widely viewed by many as a threat to satnav, to present at their November 15 meeting. If the company accepts, it could illuminate the structure of the terrestrial service it has in mind and either ease, or add fuel to, the ongoing dispute between Ligado and the GPS community.

As a child Stan Honey taught himself navigation and he admits he was “always good at math” and “just found navigation interesting.”
When he shared his many tales with the crowd in the Oregon Ballroom Tuesday night at the ION GNSS+ during the Plenary Session, the Yale- and Stanford-trained engineer entertained the audience with a wealth of information on early navigation systems, current navigation technologies, and how he and his colleagues developed many of the systems used to enhance the way millions of fans watch sports on television.

If all goes as planned the world’s satellite navigation providers will be launching dozens of satellites between now and the end of the decade.
The activity just this year and next is remarkable, said John Betz of the MITRE Corp., who co-chaired the panel with José- Ángel Ávila-Rodriguez of the European Space Agency.

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.
