RRS Telemetry Receiving System and Signal Processing System

Below are photos of the prototype Telemetry Receiver System (TRS) and Signal Processing System (SPS) currently under development. The TRS is used to track and receive signals from the in flight GPS radiosonde. The SPS processes the transmitted radiosonde telemetry and computes air pressure, temperature, relative humidity and winds.

The TRS antenna dish comes in two pieces.
