International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the Real-Time/Post-Flight Processing System (RT/PFP) developed under the Air Force Flight Test Center (AFFTC) Advanced Data Acquisition and Processing Systems (ADAPS) development program. The RT/PFP is currently being deployed at all Range Division Mission Control Facilities as the principal Range Division telemetry processing system. This paper provides an overview of the RT/PFP system, its current capabilities, and future enhancements being developed. The RT/PFP is currently used to support the F-22 flight test program, and to provide telemetry processing support for the AFFTC Range Safety Office. The RT/PFP is also used in a mobile configuration to support the Advanced Fighter Technology Integration program.
