Key Features

Five-Mode Positioning

Multi-system satellite positioning improves availability and navigation stability for FPV aircraft.

50+ Satellite Support

The receiver can search for more than 50 satellites for reliable positioning in suitable environments.

10Hz Update Rate

A 10Hz navigation update rate provides frequent position data for responsive flight-control applications.

2m Positioning Accuracy

Typical horizontal accuracy of 2m CEP50 supports GPS Rescue, return-to-home and navigation functions.

Fast Satellite Acquisition

The receiver supports a cold start of 20 seconds or less and a hot start of one second or less.

High Tracking Sensitivity

Tracking sensitivity of −167dBm helps maintain satellite reception during dynamic flight.

Multiple Size Options

P15 Pro, P18 Pro and P25 Pro dimensions support compact racing builds and larger navigation platforms.

P25 Pro Compass

The P25 Pro adds an integrated compass with SDA and SCL connections for heading information.

Technical Highlights

High-Performance FPV Positioning

The P15 Pro, P18 Pro and P25 Pro modules combine five-mode GNSS positioning, a 10Hz update rate and support for more than 50 satellites. This provides frequent and reliable position data for FPV flight-control functions.

Fast Cold and Hot Start

The modules support a cold-start time of 20 seconds or less and a hot-start time of one second or less under suitable reception conditions, reducing the waiting time before flight.

Accurate Navigation Data

Horizontal positioning accuracy of 2m CEP50 and speed accuracy of 0.05m/s support GPS Rescue, return-to-home, waypoint navigation and flight-data recording.

High-Sensitivity Satellite Reception

Tracking sensitivity reaches −167dBm, while recapture and hot-start sensitivity reach −160dBm. The high-sensitivity receiver improves positioning stability in dynamic FPV applications.

Three Installation Sizes

The compact P15 Pro is designed for space-limited aircraft, the P18 Pro provides a balanced general-purpose option, and the larger P25 Pro adds an integrated compass for navigation applications requiring heading data.

Wide Flight-Software Compatibility

The GPS series supports Betaflight, INAV, ArduPilot and Mission Planner environments, allowing integration with racing drones, fixed-wing aircraft, multirotors and autonomous RC platforms.

FAQ

What are the BZGNSS P15 Pro, P18 Pro and P25 Pro?
They are high-performance FPV GPS modules designed for racing drones, freestyle drones, fixed-wing aircraft, multirotors and other RC positioning applications.
What is the difference between the three models?
The main differences are their dimensions, weight and connector type. The P25 Pro also includes an integrated compass, while the P15 Pro and P18 Pro do not.
Which model is the smallest?
The P15 Pro is the smallest model at 17.3 × 17.3 × 9.3mm and weighs approximately 6.8g without the cable.
Which model includes a compass?
Only the P25 Pro includes an integrated compass. It uses additional SDA and SCL connections for compass communication.
How many satellites can the modules receive?
All three models support searching for more than 50 satellites under suitable reception conditions.
What is the positioning update rate?
The P15 Pro, P18 Pro and P25 Pro provide a 10Hz navigation update rate.
What is the positioning accuracy?
The specified horizontal positioning accuracy is approximately 2m CEP50 under suitable satellite reception conditions.
How long does the GPS take to obtain a fix?
The specified cold-start time is 20 seconds or less, while the hot-start time is one second or less under suitable operating conditions.
What voltage do the modules require?
All three models require a regulated 5V DC power supply from the flight controller or another suitable source.
Which flight-control software is supported?
The modules support Betaflight, INAV, ArduPilot and Mission Planner environments when correctly wired and configured.
How should the UART wires be connected?
Connect GPS TX to the flight-controller RX pad and GPS RX to the flight-controller TX pad. Connect 5V and GND with the correct polarity.
How is the P25 Pro compass connected?
In addition to 5V, GND, TX and RX, connect the P25 Pro SDA wire to the flight-controller SDA pad and its SCL wire to the flight-controller SCL pad.
How does the PPS indicator work?
The indicator remains steady before positioning is completed and flashes after the receiver obtains a valid position fix.
Where should the GPS module be installed?
Install it with the antenna facing upward and as far as practical from the VTX, ESC, motors, battery leads and other sources of electromagnetic interference.
