Product Description:

K825 GNSS Module

The K825 advanced model offers support for L1, L2, and L5 frequencies, effectively reducing the effects of ionospheric disturbances. Featuring GNSS combined with INS navigation, this dual-antenna GNSS module is well-suited for a variety of applications, including unmanned aerial vehicles (UAVs), robotics, marine systems, unmanned ground vehicles (UGVs), portable terminals, deformation monitoring, geographic information systems (GIS), and machine control.

• Features


01. Dual-antenna Design for Robust Heading and Positioning	02. Full-constelleation multi-frequency tracking
03. Support L-Band and PPP	04. Support GNSS+INS navigation
05. Surface-mounted design and small size for integration	06. High-performance floating-point arithmetic
07. Industry-leading low power consumption	08. Internal adaptive anti-interference algorithm

• Robust positioning and heading

The K825 features a dual-antenna configuration that provides accurate positioning and heading data for a range of unmanned systems.

• Easy to integrate

The K825 module, measuring 30mm by 40mm and having a thickness of 3.2mm, features a surface-mounted design that facilitates user integration. Its power consumption is notably low, at just 1.6W.

• INS+GNSS navigation

The K825 device is capable of delivering continuous and high-quality positioning data in challenging environments, including tunnels, buildings, and forests, thanks to its inertial navigation fusion algorithm and an IMU data update rate of up to 20Hz.
