In 2002, the GPS Wing started developing LADO as its replacement for mainframe-based Air Force Satellite Control Network (AFSCN) Command and Control System (CCS). LADO is based on Braxton Technologies ACE Premier™ commercial satellite ground system product line. LADO consists of three major functions: 1) Telemetry, Tracking and Control (TT&C), 2) Mission Planning, and 3) LADO Simulation. The TT&C provides the commanding of the satellite(s), sending and receiving telemetry as well as tracking data. Mission Planning is responsible for the planning and execution of satellite maneuvers during launch and early orbit (LEO), anomaly resolution and disposal activities. The LADO Simulator provides a simulation of telemetry, commanding and selected subsystems functionality for the different block type satellites forming the GPS constellation. It also provides simulation of specified maneuvers and anomalies, as well as ground facilities utilized for the LADO mission. In October 2007, LADO transitioned to operations with the launch of GPS IIR-17(M). Since then, AFSPC crews have used LADO to dispose of multiple older GPS satellites, launch the remaining GPS IIR-Ms, and all of the GPS IIF satellites currently on orbit. It has also been found to be “mission capable” by AFSPC operational testers and was “operationally accepted” by HQ AFSPC/A3. LADO is also used to fly all residual GPS Block II satellites in case of sudden on orbit failure of one of the primary satellites in the constellation. LADO has successfully launched 13 GPS satellites to include five IIR-M and eight IIF vehicles. Braxton performs unit code testing, test case development, functional testing, integration testing, and provided a low risk transition approach for incorporation of IIF launch capabilities into an existing SOC. Braxton continues to provide the sustainment and maintenance of the GPS LADO system today.
