Product overview
The YANGDA TR20 ADS-B transceiver brings position broadcasting, traffic reception and GNSS positioning together in a compact unit for drones and small aircraft. Its ADS-B In and Out functions exchange aircraft position information to support real-time airspace awareness and help reduce collision risk. The transceiver complies with DO-260B and uses 1090ES squitter signals in DF17 and DF18 formats. Integrated multi-mode GNSS supports SBAS and provides horizontal accuracy of less than 2.5m. The unit weighs 90g and measures 64x53x17 mm.
For installation, the TR20 provides an XT30PW-M20 main power interface, a J30J RS422 interface and a GH1.25-4P UART TTL 3.3V interface; both communication interfaces support baud rates of 9600–921600. SMA connections serve the 1090MHz ADS-B antenna and GNSS antenna. Supply voltage is 12V, with an 8V minimum and 35V maximum, while average power consumption is 2W. Operating temperature extends from -30°C to 85°C. RF transmit power is 43dBm (20W), with a transmission range of 50km.
