GPS III System Operations Concepts

O. Luba, L. Boyd, A. Gower

Abstract:	Over the past 3 years, the Lockheed Martin GPS III team has analyzed potential operational concepts for the Air Force. The completed tasks support the government's objective of a "realizable and operationally feasible" U.S. Strategic Command (USSTRATCOM) and Air Force Space Command (AFSPC) concept of operations. This paper provides an overview of the operational improvements for command and control of satellites and provision of the safe, precise navigation and timing services to end-users. The GPS III system changes existing operational paradigms. Improved operator capabilities are enabled by a new high-speed uplink/downlink and crosslink communication architecture. Continuous connectivity allows operators a "contact one satellite - contact all satellites" concept enabling near-real time navigation updates and telemetry monitoring. This paper describes potential improvements for the following operations: • Constellation Monitoring • Command and Control • Upload Monitoring • Global Service Monitoring • Global Service Prediction • Civilian Navigation (CNAV) Messaging • Anomaly Detection and Resolution This paper also describes future operational improvements as GPS applications continue to proliferate and the need for an improved infrastructure to effectively manage all the systems that affect GPS service grows. The views expressed in this paper are those of the authors and do not reflect the official policy or position of the GPS Joint Program Office (JPO), Air Force Space Command (AFSPC), the United States Air Force, the Department of Defense, or the U.S. Government.
