Product Advantages


Innovative Design and Modular Integration

Engineered with a compact φ44 × 40.6 mm footprint and lightweight 14 g construction, this mosaic-G5 GNSS module offers versatile mechanical integration into small and medium UAVs. The inclusion of an 8-pin GH1.25 mm connector ensures straightforward electrical connection and system compatibility. Dual base/rover modes facilitate flexible deployment scenarios, while the low-voltage operation (3.0–5.5 V) supports power-efficient system design. The multi constellation GNSS module architecture enhances antenna diversity and spatial signal acquisition, optimizing satellite visibility and positioning reliability across various global regions and operational environments.


Optimized Performance and User-Centric Features

With centimeter-level RTK positioning accuracy and rapid update frequencies, this industrial RTK navigation module delivers real-time performance crucial for precise flight control and autonomous mission execution. The module’s support for multiple GNSS protocols and fast baud rates reduces integration complexity and allows easy pairing with existing navigation systems. Low-noise RF design enhances reliability, minimizing positioning errors caused by signal interference or multipath effects. This translates to smoother UAV operation, reduced pilot intervention, and consistent mission success, making it a valuable component for developers and operators seeking dependable high-precision navigation technology.



丨 Product Introduction



    Our company's AK737, a GNSS receiver made of mosaic-G5 chip module, has excellent performance and can simultaneously receive signals from multiple satellite systems such as GPS, Beidou, GLONASS, etc., achieving centimeter level or even higher precision positioning. It has advanced algorithms built-in, which can effectively deal with complex environmental interference, high data update rate, and can output accurate position and speed information in real time.

characteristic:

Multi system compatibility: supports global satellite systems such as Beidou and GPS, and achieves high-precision joint positioning.

Centimeter level accuracy: RTK technology achieves horizontal accuracy of 0.6cm+0.5ppm, vertical accuracy of 1cm+1ppm, and speed measurement of 3cm/s.

20Hz high update rate: fast response to dynamic scenes, strong real-time performance.

Dual mode flexible configuration: can be set as a base station or a mobile station.

Wide compatibility: compatible with flight control systems such as Pixhawk and APM, easy to integrate.

Low noise design: Industrial grade RF circuit to improve signal reception quality.

Signal Name

Signal Description

1

VCC

Main power supply input, +3.3V to +5V

2

GND

Module ground, this is the negative end of the power supply or the common ground point, used to complete the power circuit.

3

TX

Transmit - This pin is used in serial communication to send data to another device.

4

RX

Receive - This pin is used in serial communication to receive data from another device.

5

SCL

Serial Clock - In the I²C communication protocol, this is the clock signal line used to synchronize data transmission.

6

SDA

Serial Data - In the I²C communication protocol, this is the line used for data transmission.

Note: Typically, VCC and GND are used for power supply, TX and RX are used for serial communication, while SCL and SDA are used for I²C communication. These interfaces allow the receiver to exchange power supply and data with external devices.

Application in UAV Autopilot Systems

In unmanned aerial vehicle operations, integrating this multi band GNSS receiver module into autopilot systems enables centimeter-level accuracy necessary for autonomous flight control. Operating within challenging outdoor environments, the module maintains stable satellite tracking across multiple constellations, ensuring uninterrupted RTK corrections for precise positioning. This capability supports complex mission profiles such as terrain-following, precise waypoint navigation, and automated data capturing. The compatibility with TTL serial interfaces and standard RTK protocols simplifies integration with flight controllers, allowing system architects to deploy reliable navigation hardware that enhances flight safety and operational efficiency.


Role in Precision Surveying and Geospatial Data Collection

For geospatial professionals requiring high-accuracy measurements, the mosaic-G5 GNSS module acts as a critical positioning tool in surveying and mapping workflows. Its multi constellation GNSS module technology ensures strong signal reception in environments with partial obstructions, such as urban or forested areas. Acting as either a rover receiver or base station, the module supports RTK networks delivering real-time centimeter-level location data. This precision facilitates accurate mapping, reduces post-processing time, and improves data reliability for infrastructure planning, agricultural monitoring, and environmental analysis. Integration with standard communication protocols streamlines the module’s inclusion into survey instruments and data logging systems, supporting efficient field operations.
