GEPRC GEP-M1025Q GPS Module – High-Precision M10 Navigation Hub with Integrated Magnetometer Compass

Achieve exceptional tactical positioning and fast satellite locks with the GEPRC GEP-M1025Q GPS Module. Engineered specifically for long-range FPV freestyle drones, professional cinematic multirotors, and custom sUAS platforms, this premium navigation module leverages u-blox’s cutting-edge M10050 processing chip architecture. By executing joint positioning across a dense multi-satellite grid—simultaneously processing GPS, BDS (BeiDou), Galileo, QZSS, and SBAS signals—the GEP-M1025Q tracks up to 32 satellites at once. Its defining physical feature is a massive, high-efficiency 25x25mm ceramic patch antenna, which dramatically increases surface area reception compared to micro-sized GPS units. This ensures stable connection quality and superior noise filtration even under thick forest canopy, around urban obstructions, or during aggressive high-G maneuvers.

Beyond rapid coordinate calculation, the specialized "Q" version integrates an onboard QMC5883L digital magnetometer compass. This sensor supplies your flight controller with real-time azimuth pointing and heading data, fulfilling the strict hardware requirements needed for safe Betaflight or INAV GPS Rescue routines and fully autonomous waypoint navigation. The module is built with an internal Flash memory chip and a high-capacity Farad capacitor, working in tandem to preserve custom user configuration settings and retain recent satellite ephemeris data. This layout enables rapid, second-long hot starts during field battery swaps, minimizing pad-prep delays. Complete with a clear onboard status LED indicator and an ultra-flexible pre-terminated wiring loom, this micro navigation hub provides industrial-grade reliability for custom unmanned systems, academic aerospace research, and high-performance RC hobby builds.
