Global Positioning System (GPS) Civil Signal Monitoring (CSM) Trade Study Report

This Global Positioning System (GPS) Civil Signal Monitoring (CSM) Trade Study has been performed at the direction of Department of Transportation/Federal Aviation Administration (DOT/FAA) Navigation Programs as the agency of reference for consolidating civil monitoring requirements on GPS. The objective of this trade study is to develop recommendations to DOT leadership on viable paths for achieving the requisite monitoring of GPS broadcast signals used by civil agencies. Civil unique GPS signal monitoring needs have been consolidated into the GPS Civil Monitoring Performance Specification (CMPS). The trade study activity examined alternatives including use of the Next Generation Operational Control System (OCX) segment as well as Non-OCX elements for implementing civil signal monitoring, completed a comparative evaluation of the OCX/Non-OCX/hybrid alternatives available, and documented assumptions and risks associated with the trades.
