GPS Operational Control System Modernization: Alternative Architectural Concepts

Jaynarayan Lala and Laura Burkhardt

Abstract:	This paper discusses options for modernizing the ground control facilities of the Global Positioning System (GPS). Specifically, it discusses the S-band command and status functions that are performed by the Ground Antennas (GAS). In addition to describing hardware upgrades for the GAS, it compares centralized and distributed processing options and describes a transition strategy for migrating from the existing legacy system to a new, modernized system.
