The TR-1A is the second generation of the smallest ADS-B transceivers on the market and is designed for civil and commercial UAV systems.

The device operates at 1090 MHz and allows receiving and sending ADS-B data with a defined output power of 0.25, 0.5 or 1 watt. No external devices are required to operate the transceiver.

It is equipped with a high-quality multi-GNSS receiver and a pressure sensor. The aluminum body and ESD protection guarantee a high resistance of the device to difficult conditions. TR-1A opens the way to implement the Detect and Avoid algorithms and supports the integration of UAS into the airspace.
