The purpose of this document is to provide a comprehensive compilation of requirements for monitoring the GPS civil service and signals based on top level requirements to monitor all signals all the time. Upon approval this CMPS will be used by the GPS community to determine the adequacy of civil monitoring and provide focus for any needed monitoring improvements.
