Which is exactly was is happening - apart from I don’t believe QinetiQ are involved (but I might be wrong). I believe that NATS is a stakeholder without a commercial interest in the technology used, their only interest is to improve the way airspace is used (which could save them money).
GOODWOOD TRIAL INFORMATION, 26 AUGUST - 23 SEPTEMBER 2021
Between 26 August 2021 and 23 September 2021, Traffic Information Services-Broadcast (TIS-B) and Flight Information Services-Broadcast (FIS-B) will be transmitted from Lasham and Goodwood Aerodromes. The project may seek to extend this evaluation period. The service is part of a trial that is underway around Goodwood Aerodrome that aims to develop new surveillance technology and operational procedures in support of Beyond Visual Line of Sight (BVLoS) operations. The specific objective of the TIS-B element of the Goodwood trial is to “Demonstrate and evaluate the benefits of broadcasting a surveillance ‘’picture’’ via TIS-B. This is comprised of a consolidated surveillance data feed from Mode A/S transponders, ADS-B transponders and transceivers, MLAT, and FLARM’’ which can be received via ADS-B 978 MHz receivers, including CAP1391 devices. Visualisation will occur on suitable Electronic Flight Bag applications. In addition, the FIS-B broadcast will include weather and airspace information such as the activation status of Temporary Danger Area (TDA) EG D097. The transmitting radius of the stations is approximately 40 NM in a circular direction above 500 FT, from each transmitter.
