GEPRC GEP-M1025-DI GPS Module

The GEPRC GEP-M1025-DI is an advanced 10th-generation GPS module designed for reliable autonomous positioning, rescue modes, and return-to-home (RTH) functions. Built around the modern u-blox M10 architecture and equipped with a substantial 25x25mm ceramic patch antenna, it pulls in more satellites with faster lock times than older M8 series units—even in challenging signal environments like dense tree canopies or urban valleys.

Key features

• Powered by the u-blox M10 chipset for concurrent multi-constellation reception.
• High-gain 25x25mm ceramic patch antenna significantly improves signal acquisition and stability.
• Delivers faster cold-start locks and tighter positioning accuracy compared to previous generations.
• Standard UART interface ensures straightforward wiring to modern flight controllers.

Specifications

• Core chipset: u-blox M10
• Supported constellations: GPS, GLONASS, Galileo, BDS
• Antenna dimensions: 25x25 mm
• Interface: UART
• Input voltage: 5V
• Supported firmware: Betaflight, INAV, ArduPilot

Because of its larger 25mm footprint, this module is best suited for 5-inch freestyle frames, 7-inch long-range cruisers, and heavy-lift cinelifters where the top plate or TPU mounts can comfortably accommodate a full-sized GPS unit for maximum satellite reception.
