ADH-Tech GP-735 56-Channel GPS Receiver Module

The GP-735 connects via a standard TTL serial interface, making it compatible with most flight controllers supporting UART-based GPS inputs. This includes popular systems like Betaflight, ArduPilot (Mission Planner), and PX4, found in many FPV and autonomous drones. Ensure correct wiring for VCC, GND, TX, and RX to the flight controller's UART port for seamless integration.

The high tracking sensitivity of -162dBm allows the GP-735 to maintain a strong lock on weak satellite signals. This is crucial for drones operating in challenging environments, such as urban areas with tall buildings or areas with partial canopy cover. It ensures more consistent and reliable positional data, improving navigation accuracy and reducing the risk of signal loss during flight.

The 56-channel capability allows the GPS module to track a larger number of satellites simultaneously, leading to faster acquisition times and improved positional accuracy. Combined with an adjustable update rate up to 10Hz, it provides more frequent and precise location updates. This is vital for fast-moving FPV drones and autonomous UAVs requiring dynamic and real-time navigation data.

Yes, the ADH-Tech GP-735 features a built-in onboard antenna, eliminating the need for an external antenna. This design significantly simplifies installation, reduces the overall size and weight of the module, and makes it ideal for compact drone builds and space-constrained applications. While convenient, optimal placement with a clear sky view is still recommended for best performance.
