The launch of uAvionix’s new ping978EC 978MHz UAT ADS-B transceiver provides a critical technology path for UK operators to meet evolving Civil Aviation Authority regulations for beyond visual line of sight drone operations.
This new hardware enables compliance with the latest electronic conspicuity requirements specifically for UAS BVLOS operations in the “Specific” category. The device adheres to CAA CAP 1391 Appendix E and satisfies the requirements set out in CAA CAP 3040 for operations within atypical air environments, meeting the RTCA DO-282B Class A1S performance standard.
A significant shift in this technology is the reduction of administrative tasks for operators. While an Ofcom UAS Operator Radio Licence is still required to broadcast, users no longer need to apply to the CAA for a permanent ICAO 24-bit Aircraft Address. In accordance with 978MHz UAT regulations, the transceiver dynamically generates a unique, temporary, self-assigned 24-bit address each time it gains a GPS fix upon powering up.
To further streamline the Operational Authorisation process, a Statement of Compliance is available for operators to submit directly to their RPAS Inspector, fulfilling the specification requirements of CAP 1391.
Technologically, the unit is built on established ADS-B platforms and is designed with a focus on low size, weight, and power (SWaP) characteristics. It weighs 26 grams including the antenna and measures 50x25x18mm. The system broadcasts on 978MHz UAT at 20W power while detecting traffic on both 1090MHz and 978MHz frequencies. It features an integrated precision barometric pressure sensor and a high-integrity GNSS sensor derived from TSO C-199 FYX technology.
Configuration is handled via a dedicated mobile application on iOS or Android, allowing pilots to set callsigns and squawk codes. The transceiver is also compatible with existing ground-based situational awareness tools such as FlightLine, pingStation 3, and skyAlert, ensuring that both field operators and command centers can monitor the UAV and surrounding ADS-B equipped air traffic in real time.
