Product manual

Product Introduction

The GNS120 integrated inertial navigation system, developed by RUICOM Technology, is based on a MEMS inertial measurement platform and integrates RTK dual-antenna positioning technology. By fusing angular rate information from the gyroscope and acceleration measurement data from the accelerometer, the system performs dynamic attitude calculations and can output the attitude angle, azimuth angle, velocity, position, and three-axis angular velocity and three-axis acceleration of the measured object in real time. The product incorporates RUICOM Technology's independently developed GNSS/inertial integrated navigation algorithm, employing a Kalman filter model to provide real-time feedback and compensation for system errors and IMU instrument errors, suppressing error accumulation and mitigating the effects of short-term gyroscope drift.

This product is primarily suitable for applications such as mobile satellite antenna equipment, vehicle guidance systems, and attitude and azimuth control of unmanned aerial vehicles (Model Flights).

1.The test results may deviate due to the influence of atmospheric conditions, baseline length, GNSS antenna type, multipath, number of visible satellites, and satellite geometry. 2. Measurements are conducted using a 1-kilometer baseline and a receiver with good antenna performance, disregarding potential antenna phase center offset errors. Note: After power-on, it will start up after being idle for 5 seconds.
