An Operational Control Segment (OCS) Update on GPS Constellation Status and Future Program Directions

Abstract

We run the GPS Master Control Station from the Second Space Operation Squadron out of Falcon Air Force Base, Colorado. This is our squadron symbol (Figure 1); the real story here is a big success story in terms of where GPS has gone and especially how PTTI applications have been so much a big part of GPS and how much a part of PTTI that GPS has become. They asked me to speak this year and give you an update on what is going on with GPS. The message as far as GPS and PTTI are concerned is all a good one. I want to talk a few minutes this afternoon about the performance of GPS and then discuss the Federal Radionavigation Plan (Figure 2), which is a document outside the purview of the Department of Defense (DoD) and the Department of Transportation (DoT). One of the concerns with GPS, to not only the time users, but to a lot of other folks, is that the DoD has pretty much guarded GPS operations; and I want to talk a little bit about what the DoD and the DoT have signed up to in terms of assurances to this community and to aviation interests, as well as other modes of transportation in terms of GPS continuity and availability. Finally, I will bring up a couple of issues that hopefully will be of interest to many in this group.
