ADS-B and Flarm transceiver in one device

The TR1F belongs to the generation of the smallest transceivers on the market and supports two technologies: ADS-B and FLARM. It is designed to support civil and commercial unmanned aircraft systems, as well as general aviation.

The device operates at 1090 MHz and 868 MHz and allows receiving and sending ADSB and FALRM data with a defined output power of 0.25, 0.5 or 1 watt for ADS-B and 0.025 watt for FALRM. No external devices are required to operate the transceiver. It is equipped with a high-quality multi-GNSS receiver and an air pressure sensor. The aluminum body and ESD protection guarantee a high resistance of the device to difficult conditions. The TR-1F opens the way to safely integrate UAS into non-segregated airspace, implement the Detect and Avoid algorithms and reduce segregation between airspace users.

NOTE: A FLARM UAS license is required for operation with FLARM frequency. The license can be obtained with the device upon purchase.
