NAV-300 Integrated Navigation System

High-Precision, Industrial-Grade Navigation Core

the NAV-300 is a high-reliability and high-precision industrial-grade integrated navigation system. It provides precise positioning, orientation, and attitude information, making it ideal for navigation and measurement in aviation, maritime, and ground robotics applications


🌟 Key Features

  • Comprehensive Motion Output: Delivers high-frequency and high-precision output of position, altitude, velocity, attitude, and heading through integrated multi-sensor fusion algorithms.
  • Precision GNSS & RTK: Features a built-in multi-system, multi-frequency satellite receiver supporting RTK centimeter-level positioning and dual-antenna heading determination.
  • Navigation in Challenging Environments: Equipped with advanced GNSS-denied navigation algorithms, providing reliable attitude and altitude information even when satellite signals are lost.
  • Integrated Sensor Suite: Includes redundant MEMS Inertial Measurement Units (IMUs), a barometric sensor, and a high-performance satellite receiver.
  • Compact & Robust: Designed for easy integration with a small footprint ($76 \times 58 \times 25\text{ mm}$), weighing only $105\text{ g}$—a true plug-and-play solution.
  • Highly Extensible: The expansion interface allows for the connection of external sensors such as magnetic compasses, backup GNSS systems, and odometers.
