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 Pedestal, front view. The Signal Processing System (see the photo below) will be located in the space above the 24 volt power supply. The UPS can provide sufficient back up power for up to 2 hours (enough power to complete a flight).
The TRS Pedestal, back view. The TRS is equipped with heating and cooling systems. The heating systems also force warm air into the antenna assembly.
