Comms on the move Electronic Steerable Antenna Test (CESAT) – Compact Antenna Test Range (CATR)

The CATR will form the basis and be used to support the test and performance measurements of satellite mobile phased-array antennas and terminals, in dynamic scenarios, where both the satellite and user are in motion and operating in the L S, C, X band Ku and Ka frequency bands (1 Ghz - 32 GHz). Required components are outlined in the supporting documentation. The proposed system while is made up of a baseline CATR, the final system will make use of robotic arms to provide the movement of a novel phased array to replicate a LEO satellite in orbital motion, a fixed positioner that has capability to replicate movement relative to a vehicle, ship or aircraft. Where the device under test is being exercised in an emulated RF environment and the performance of such a DUT can be characterised. This will include thermal transitions to emulate the true operating environment the terminal would endure. This procurement is for a new CATR only.
