Radiolink SE100 u-blox M8 GPS with GPS Holder

The Radiolink SE100 is a u-blox M8 GPS and compass module tailored for reliable autonomous flight on Pixhawk and APM flight controllers. Built around the UBX-M8030 chipset, it offers rapid satellite acquisition — Radiolink rates it at up to 50 cm positioning accuracy under open sky, though as a standard (non-RTK) GNSS receiver expect metre-level accuracy in everyday flying — making it suited for fixed-wing mapping builds, multirotor camera rigs, and heavy-lift agricultural drones.

Key features

• Supports GPS/QZSS, GLONASS and BeiDou, tracking two satellite systems concurrently for fast lock and positional stability.

• Integrated hardware-based magnetic compass for precise heading telemetry during autonomous waypoint missions.

• Includes a folding GPX mast bracket to elevate the module away from electromagnetic interference caused by the drone's power distribution board.

• Built-in signal amplifier (LNA) and SAW filter to maximise weak-signal reception in challenging environments.

Specifications

• GNSS Chipset: u-blox UBX-M8030

• Supported constellations: GPS, GLONASS, BeiDou, QZSS (two concurrently)

• Positional accuracy: 0.5 metres

• Compass: QMC5883L (integrated, I2C)

• Input voltage: 5V

• Update rate: 10 Hz

• Time to first fix: 26 s cold start, 1 s hot start

• Dimensions: approx. 48 x 41 x 15 mm

Provided with its own collapsible mast, the SE100 is simple to mount securely on larger frames where isolating the magnetometer from high-current electronics is critical for flight stability.
