The transmitter only has to leave the aircraft. The receiver has to recover the data after the link has been through range, multipath, antenna pattern nulls and airframe blockage — which is why the ground segment decides how much of a test flight is actually usable.
Chassis
CNC-machined from solid aluminium in the same housing family as the TTS transmitters, so one bracket pattern and one harness style cover both ends of the link. The lid is cut as an integrated heatsink; the two RF inputs and the 25-pin Micro-D sit on opposite faces. Available in two anodised finishes.

Reception
A single antenna on a moving airframe will find a null sooner or later. Diversity reception takes the signal from more than one antenna or receiver and combines them, so a fade on one path is covered by the other rather than becoming a dropout in the record.
Combining is done on signal quality, continuously. The output is a single recovered stream that is better than either input on its own — not a switch between them with a seam at every changeover.
Signal Processing
Reception covers the IRIG-106 waveform set, so the receiver matches whatever the airborne transmitter is configured to send rather than constraining the test to one modulation.
Bit synchronisation and clock recovery run on the demodulated stream, producing the clean, aligned data the downstream decommutation and recording chain expects.
Smart Diagnostics
One status LED on the RF face reads out power, self-test, carrier lock and fault state — readable across the ground station without opening a terminal.
Input power is present and the unit is booting. The LED holds white through power-up until the self-tests complete.
Deployment
A receiver is only as useful as its place in the ground station. Output feeds decommutation, recording and real-time display, while the antenna side works alongside the tracking pedestal that keeps the aperture on the aircraft.
Paired with a TRACER pedestal and a TTS transmitter, the TRS-1S completes a chain RFBIT builds end to end — one supplier for the airborne unit, the pedestal and the ground receiver.
