High Performance GNSS -Aided Integrated Navigation System
Brief Introduction
SK200 is a high-performance, surface-mount GNSS-assisted inertial navigation system (GNSS/INS) that integrates a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer, barometer, high-sensitivity GNSS receiver, and microprocessor. In comparison to standalone GNSS modules or Attitude and Heading Reference Systems (AHRS), SK200 employs an Extended Kalman Filter algorithm to loosely couple the position and velocity outputs from the GNSS receiver with the acceleration and angular data from MEMS inertial sensors. This fusion approach delivers precise estimates of position, velocity, and attitude, while also enhancing dynamic performance.To ensure the accurate output data, SK200 is calibrated strictly over full temperature by the factory, to reduce the effects of bias error, scale factor error, cross-axis error and temperature changes on the accuracy of MEMS inertial sensor.Additionally, SK200 integrates barometer and magnetometer outputs, providing a significant advantage in altitude and attitude measurement. Leveraging a multi-sensor data fusion algorithm and specialized processing for various scenarios, SK200 is versatile and can be applied in a wide range of applications. It is especially well-suited for unmanned aerial vehicles (UAVs), unmanned underwater vehicles (UUVs), AGV carts, robots, and more.
