K823 GNSS OEM module

The K823 is a dual-antenna dual-frequency and full-constellation GNSS OEM board with an IMU module, which provides robust high-precision positioning and heading information. It has been designed specifically for use in unmanned aerial vehicles (UAVs), robotic systems, 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.GPS L1/L2, BeiDou B1/B3, GLONASS L1/L2, Galileo E1/E5b, QZSS, SBAS, IRNSS
03.BeiDou Global Signal B1C, B2b	04.Support L-Band and PPP
05.Support GNSS+INS navigation	06.Surface-mounted design and small size for integration
07.High-performance floating-point arithmetic	08.Industry-leading low power consumption
09.Internal adaptive anti-interference algorithm

• Robust positioning and heading

The K823 is designed with a dual-antenna configuration that enables the delivery of high-precision positioning and heading information for a range of unmanned systems.

• Easy to integrate

The K823 is a 30mm×40mm×3.2mm module with a surface-mounted design, rendering it an optimal choice for users seeking to integrate it into their systems. Its power consumption is notably low, at less than 1.6W.

• INS+GNSS navigation

The K823 is designed with an onboard high-precision IMU module, which is capable of providing continuous and high-quality positioning data through the use of an inertial navigation fusion algorithm.
