GEPRC GEP-M1025-MQ GPS Module

The GEPRC GEP-M1025-MQ is a high-gain GPS and compass module built around the 10th generation u-blox M10 chipset. Designed for long-range FPV drones, cinelifters, and autonomous builds requiring reliable position hold, it utilises a large 25x25mm ceramic patch antenna for rapid satellite acquisition and strong signal retention even in challenging conditions.

Key features

• Integrates a magnetometer to provide accurate heading data for INAV, ArduPilot, and Betaflight Rescue functions.
• Receives up to three GNSS constellations concurrently (GPS, Galileo, and BeiDou) for maximum positional accuracy and high satellite counts.
• Features a built-in farad capacitor to maintain ephemeris data, enabling rapid hot-start lock times between battery swaps.
• Communicates via a standard 6-pin SH1.0 connector, breaking out both UART (GPS) and I2C (compass) lines.

Specifications

• GNSS receiver: u-blox M10
• Compass: Integrated
• Antenna dimensions: 25 x 25 mm
• Input voltage: 3.3V - 5V
• Baud rate: 115200 bps
• Refresh rate: 10Hz
• Supported protocols: UBLOX (GPS), I2C (Compass)

Due to its larger footprint, the M1025-MQ is best suited for 7-inch frames, X-Class builds, and macroquads where top-plate mounting space permits a full-sized 25mm GPS module.
