I have long been an advocate of signal diversity as a solution to many of the ills that plague the GPS user, especially outdated user equipment. The best equipment, if it were available today, would be the PHGPST or Perfect Handheld GPS Transceiver. I cannot count the thousands of letters and...More>>

There is a reason the Munich Satellite Summit is billed as a summit and not a symposium or conference. It’s a different atmosphere that invites group chats, informal get-togethers, and networking. One item of note that I came away with is that the Chinese are looking for help and partners for...More>>

Jennifer Grant, the 2SOPS/CC at Schriever AFB, the home of GPS, to help us with our year-end review and crystal-ball...More>>

This month there is good news — great news, actually — where GPS and PNT (Position, Navigation and Timing) systems are concerned. On October 22, a Russian Soyuz rocket placed in orbit the first two validation satellites, built by EADS Astrium Germany, in the Galileo PNT constellation after...More>>

Like many who had the pleasure of interacting with the genius that was Steven Paul "Steve" Jobs, I have been reflecting recently concerning his incredible impact on our lives. Indeed his impact on every aspect of our lives including GPS is almost beyond description. For example, our warfighters are...More>>
