Introduction
The K803D is a compact, high-performance GNSS module. It supports multiple constellations, offers highly reliable positioning information, and includes advanced anti-interference technology. Ideal for applications in IoT, robotics, and 5G networks.


  • Support GPS, BDS, GLONASS, Galileo, QZSS, IRNSS, SBAS
  • Support L-Band and PPP
  • Auto-IMU for 60°tilt compensation
  • Surface-mounted design and small size to integrate
  • High-performance floating-point arithmetic
  • Industry-leading low power consumption
  • Internal adaptive anti-interference algorithm
01
Easy Integration
30mm×30mm×3.2mm size module with surface-mounted design makes K803D modules ideal for users to integrate. The power consumption is lower to 0.95W.
02
In-built Newly Quantum III SoC chip
The K803D incorporates ComNav’s new generation highaccuracy Quantum III SoC chip with the capability of tracking all the GNSS constellations and signals. It can provide users with highly reliable positioning information with support of highperformance floating point arithmetic.
03
Onboard Auto-IMU for 60°Tilt Compensation
K803D is equipped with Auto-IMU, eliminating the need for manual initialization, supporting automatic calibration, and streamlining the operations in the field. K803D easily integrates with devices requiring tilt compensation, such as RTK receivers and robots.
04
Adaptive Anti-interference Technology
The K803D has internal adaptive anti-interference algorithm which enables the module effectively suppress wideband, narrowband and continuous-wave interference. It can provide users with high-quality observing data even in the complex electromagnetic environment.
