- 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.
