Real Time Telemetry Processing System (RTPS)

The freqs identified as RTPS are freqs that are assigned to the Real-Time Telemetry Processing System (RTPS) at PAX River, MD. Many sources (lists) of freqs for PAX have these freqs identified as belonging to a particular Aircraft Flight Test Program. That is not necessarily the case. These freqs are assigned by RTPS as needed. If a test aircraft flies on a regular basis, then they may very well keep the same freq for a long period of time making it appear that the freq has been permanently assigned to that particular test bed. But if that test program/aircraft goes down for a mod, goes away for off base testing, or any other reason it may not fly for a while, When it returns to flight status RTPS may very well have someone else using the old freq and give another freq to the returning aircraft/program. It has been observed in the past that 2 different flight test programs have used the same freq on a given day.
