Product overview
The RadioLink SE100(M10N) is a GPS navigation module for integration with a flight controller. Its physical architecture combines a Ublox M10050 receiver, a 2.5 dBI ceramic antenna and an integrated IST8310 electronic compass with an I2C interface. The reception chain includes a GPS-specific 20 dB MMIC amplifier and front and rear Murata surface acoustic wave filters. These components provide filtering and amplification for reception around strong interference sources, including high-power UAV video transmitters and high-voltage lines. Reception spans three frequency bands and supports four satellite systems simultaneously.
Integration requires a 5±5% VDC supply, with current specified at 50–100 mA. The connection arrangement identifies GPS and I2C ports at the PIXHAWK flight controller end. NMEA is the factory-default protocol; connection to a flight controller automatically synchronizes the port protocol at 115200 baud, while a separate baud-rate specification lists 38.4K. After disconnection and depletion of the internal supercapacitor, generally around two hours, the protocol returns to NMEA. The supplied package contains one SE100 module, one mounting bracket and one packaging box. Acquisition of 20 satellites within six seconds is specified for open terrain.
