HRM-110

Narrow-Band Radio Modem

The HRM-110 is a narrow-band radio modem for UAV and USV telemetry, command and control, with reported ranges exceeding 300 km and a maximum air data rate above 200 kbps. Optimized bands cover 470–490, 500–520, 1200–1300 and 2400–2800 MHz (custom 100 MHz–6 GHz), with frequency hopping and AES-256 encryption. Transparent UART ports are compatible with MAVLink, Modbus and Pelco protocols.
