GEPRC GEP-M1025Q GPS Module

The GEPRC GEP-M1025Q is a high-precision GPS and compass module tailored for mid-to-long-range FPV drones, cinematic cruisers, and autonomous builds. Built around the 10th-generation u-blox M10050 GNSS chipset, it locks onto satellites significantly faster and holds a more stable 3D fix than older M8-based modules.

Key features

• Integrates a large 25x25mm ceramic patch antenna for maximum signal reception, maintaining solid satellite locks even during steep FPV banking.
• Concurrent multi-constellation GNSS support pulls data from multiple networks simultaneously for high-accuracy positioning.
• Built-in QMC5883L magnetometer provides accurate heading data critical for Betaflight GPS Rescue and INAV waypoint missions.
• Standard SH1.0 6-pin connection allows for straightforward wiring to modern flight controllers.

Given its 25mm footprint, this module is best suited for 5-inch and larger freestyle, long-range, or heavy-lift frames where top-plate space is readily available. For the fastest satellite locks and accurate compass readings, mount it on a TPU base or mast away from high-current battery leads and VTX antennas to minimise electromagnetic interference.
