Product Overview — GEPRC GEP-M1025 GPS Module
The GEPRC GEP-M1025 GPS Module is the GPS-only model in GEPRC's larger M1025 navigation family. Built around the u-blox M10050 receiver, its most important physical distinction is the larger 25 × 25 mm ceramic patch antenna, selected for builds where reception performance matters more than saving the last few millimetres of space.
It supports combined GPS, BeiDou, Galileo, QZSS and SBAS operation and provides GNSS data to a compatible flight controller over UART. Built-in flash memory and a supercapacitor help preserve configuration and improve the conditions for quicker subsequent satellite starts.
The M1025 series also includes versions with additional magnetometers and barometers, but those are separate models. This specific listing is the standard GEP-M1025 GPS version: it supplies satellite positioning and should not be described as having a built-in compass or barometer.
Key Features — GEP-M1025
- Larger patch antenna: The 25 × 25 mm ceramic antenna is the defining feature of the M1025 series and provides a larger receiving element than GEPRC's 12 mm Nano and 18 mm standard M10 modules.
- M10 multi-constellation navigation: The u-blox M10050 architecture supports GPS, BeiDou, Galileo, QZSS and SBAS positioning to expand the set of usable satellites for compatible navigation systems.
- Stable satellite acquisition: GEPRC advertises fast positioning and stable signal reception. Real lock time and accuracy still depend on sky coverage, antenna orientation, RF noise and the current location.
- Flash-backed configuration: Onboard flash and a supercapacitor support retention of configuration and fast subsequent acquisition when stored assistance information remains useful.
- Easy-to-read status indication: An onboard indicator LED assists basic module-status checks during wiring and setup; precise behaviour may vary with the firmware and production revision.
- GPS-only base model: No built-in compass or barometer is included in the standard M1025. Buyers requiring those sensors should select a clearly identified Q, DQ or other sensor-equipped series variant instead.
The real performance of any GPS module also depends on your antenna installation, interference conditions and flight-controller configuration.
GNSS Reception and Navigation
The M1025 GPS family uses the modern M10 receiver for combined constellation positioning. Unlike a single-constellation receiver, this approach can make use of more satellite systems when enough of the sky is visible.
The larger 25 × 25 mm patch antenna gives this unit more antenna area than the smaller M10 models. It is especially relevant for larger FPV frames where the antenna can be placed away from carbon-fibre shielding and high-current wiring.
GEPRC uses flash memory and a supercapacitor for settings retention. The unit can therefore benefit from hot-start conditions on subsequent flights while still requiring normal satellite acquisition when first installed or after moving to a different region.

Manufacturer specifications are reference values. Installed performance and compatible features depend on the host aircraft and its flight-controller firmware.
Electrical Interfaces and Flight Controller Integration
Check that your frame has enough space for the larger module and a secure mounting platform. A sky-facing antenna position, away from powerful VTX modules and electrical interference, generally produces the best installation.
Connect the module's power, ground and UART pins according to the wiring diagram for your flight controller. Cross GPS TX to FC RX and GPS RX to FC TX if needed; do not rely on a cable's colour alone.
Enable and configure the GPS feature in the flight-controller firmware, verify satellite reception outdoors and confirm any GPS rescue, return or navigation parameters before flight. This base version does not provide I²C compass/barometer data.
Important model distinction
Images may show the wider M1025 family including labelled Q, DQ or other models. Your purchase is the standard GEP-M1025 GPS-only version, without integrated magnetometer or barometer.
Installation & Setup Guide
- Check your flight controller: Confirm the power rating, free UART pads and the supported GNSS firmware/protocol before soldering or plugging in the module.
- Choose an unobstructed position: Orient the ceramic antenna towards open sky. Keep it away from carbon-fibre shielding, VTX antenna feeds and noisy motor or battery wiring.
- Verify the wiring: Connect ground and a supported supply. Cross GPS TX to the flight controller's RX pad; connect GPS RX to TX when the firmware requires communication in both directions.
- Configure firmware: Enable GPS on the right UART, select the protocol and appropriate baud rate, and enable any additional sensors only when the specific model and controller support them.
- Test outdoors before flying: Check for a satellite fix, correct position reports and acceptable sensor readings. Inspect GPS rescue or return-to-home settings rather than assuming they activate automatically.
- Secure and retest: Mount the module firmly with safe cable strain relief and verify reception again after assembling the frame and powering the VTX.
Recommended Applications
- Long-range FPV builds: Useful on larger quadcopters where there is room for a 25 mm antenna and satellite reception is a key part of the navigation and failsafe strategy.
- Multi-rotor and fixed-wing platforms: A serial GNSS option for flight controllers that accept u-blox GPS data and supply the correct module voltage.
- Pilots prioritising antenna area: An alternative to the smaller Nano when space is less constrained and the larger receiving patch is desirable.
Which GEPRC GPS Should You Choose?
Choose the M1025 if your airframe can accommodate its 25 mm patch antenna and you need robust GNSS reception without integrated compass/barometer hardware. For compact aircraft compare the Nano; for a small combined GPS + magnetometer + barometer module, review the M10-DQ.

Before You Fly
These modules provide GNSS measurements; they do not independently fly or steer the aircraft. Satellite-assisted rescue, heading hold, waypoint functions and altitude control require appropriate flight-controller hardware, firmware, tuning and safe test procedures.

Discover GEPRC
GEPRC focuses on the FPV ecosystem, from ready-to-fly quadcopters and cinewhoops to airframes, electronics, motors and navigation accessories. Its product families serve pilots looking for cinematic flying, freestyle performance, long-range exploration or carefully selected parts for custom aircraft.
GEPRC equipment rewards attention to the complete build rather than any single component. A GPS module must match the flight controller's available connections, a battery must suit the voltage and dimensions of an airframe, and a video or radio configuration must align with the pilot's existing control and viewing system.
Explore the brand by starting with your flying style and aircraft size. Check receiver protocols, video transmission, mounting, operating voltage and firmware before choosing related parts. That compatibility-first approach makes it easier to build a dependable and purposeful FPV setup.
