The Wallops Flight Facility of the Goddard Space Flight Center has designed and built in-house a Mobile Range Control System (MRCS), which is a self-contained system to be deployed in support of rocket launches at remote ranges in cases in which termination of flight may be required for safety purposes. The MRCS includes data-acquisition subsystems, real-time data-computation subsystems, range-safety displays, command/destruct transmitters, and supporting communication subsystems, all together providing for remote range control.

Prior to the development of the MRCS, subsystems in several mobile containers were integrated on range to satisfy requirements to provide functions similar to those now performed by the MRCS. In comparison with the older collection of subsystems in separate containers, the fully integrated MRCS can be tested more completely prior to shipment, and it reduces mission-support time and cost. Improvements incorporated into the MRCS include state-of-the-art hardware and real-time software data processing which generates and displays range safety real-time instantaneous impact prediction data derived from mobile radar and telemetry tracking systems. The MRCS provides safe and reliable conduct of Expendable Launch Vehicles (ELVs) and an environment that is comfortable for operators.
