GEPRC GEP-M1025I GPS Module

The GEPRC GEP-M1025I is a robust GPS module built around the 10th-generation U-blox M10 GNSS architecture, designed for mid-to-large FPV quads, long-range builds, and cinelifters. Thanks to its larger 25x25mm ceramic patch antenna, it delivers significantly higher signal gain than nano-sized modules, ensuring rapid cold starts and stable satellite locks even in challenging RF environments.

Key features

• Powered by the U-blox M10 chip for faster satellite acquisition and superior positional accuracy over older M8 configurations.
• Features a large 25x25mm ceramic patch antenna for strong signal retention, ideal for deep valleys or heavy interference.
• Supports concurrent reception of up to three global positioning systems (GPS, Galileo, and BeiDou) for maximum satellite lock.
• Onboard flash memory retains configuration settings between battery swaps, speeding up subsequent lock times.
• Integrated I2C interface for compass connectivity, essential for reliable directional data during autonomous flight modes.

Specifications

• GNSS Receiver: U-blox M10
• Antenna: 25x25 mm ceramic patch
• Supported Constellations: GPS, Galileo, BeiDou, GLONASS
• Input Voltage: 5V
• Interfaces: UART (GPS), I2C (Compass)

Due to its larger footprint and integrated compass, this module is best suited for 7-inch long-range freestyle rigs, fixed-wing platforms, and macro-quads where dependable Return-to-Home (RTH) performance is prioritised over extreme weight savings.
