GEPRC GEP-M1025-DQ GPS Module

The GEPRC GEP-M1025-DQ is a comprehensive navigation module built around the 10th-generation u-blox UBX-M10050 chipset. Engineered with a large 25x25mm ceramic patch antenna, it excels in challenging signal environments, making it ideal for long-range FPV cruisers, heavy-lift cinelifters, and fixed-wing builds relying on precise autonomous flight. This "DQ" variant integrates both a compass and a barometer, feeding your flight controller the accurate heading and altitude data required for reliable Betaflight GPS rescue, position hold, and INAV waypoint missions.

Key features

• 10th-generation u-blox architecture combines GPS, BeiDou, Galileo, QZSS and SBAS positioning, tracking up to 32 satellites.
• Oversized 25x25mm ceramic antenna delivers faster cold locks and stronger signal retention than standard 18mm micro modules.
• Integrated compass supplies accurate yaw and heading data crucial for position hold and autonomous navigation.
• Built-in barometer provides highly precise altitude measurements.
• Onboard farad capacitor retains ephemeris data to guarantee rapid hot-start locks between battery swaps.

Specifications

• Chipset: u-blox UBX-M10050
• Antenna size: 25x25 mm
• Input voltage: 5V
• Connector: SH1.0 6-pin
• Baud rate: 115200 bps
• Communication protocol: UART (GPS), I2C (Compass & Barometer)
• Supported firmware: Betaflight, INAV, ArduPilot
• Constellations: GPS, BeiDou, Galileo, QZSS, SBAS
• Compass: QMC5883
• Barometer: DPS310 (DPS368 on some batches, identical in use)
• In the box: GPS module, terminal wire, instruction manual, heat shrink tubing

When planning your wiring, note that the GPS functionality requires a free UART (TX/RX), while the compass and barometer must share an I2C bus (SDA/SCL) on your flight controller.
