LADO (Launch, Anomaly, and Disposal Operations), a New Challenge for GPS

Surender K. Gupta and Brian M. Louie

Abstract:	The Global Positioning System (GPS) Joint Program Office (JPO) at Los Angeles Air Force Base has been the manager of the GPS program since its inception in the early seventies. The principal challenge facing the program today is to ensure that the constellation of GPS satellites remains in sound health and provides accurate navigation and timing signals to millions of civil and military users around the world 24 hours a day throughout the year. The initial launching, recovery from on-orbit anomalies, and disposal of unneeded GPS satellites has been the responsibility of the Air Force Satellite Control Network (AFSCN) and its Command & Control System (CCS). However, due to a decision to decommission CCS by Oct 05, the LADO system is being developed under the auspices of GPS JPO to perform all the functions currently performed by CCS. LADO system differs functionally as well as operationally from the constellation management aspects of the GPS system and presents new challenges to program managers.
