Product Details

ER-9100 RLG Inertial Navigation System


This RLG Inertial Navigation System built-in 0.008 °high precision laser gyroand 10 ug/hr high precision quartz accelerometer, by means of innovation of inertia compensation device error calibration and strapdown navigation technology, its precision can reach to 0.06° independent search north accuracy and 1 nmile/hr autonomous navigation accuracy.

In order to ensure compatibility requirements, ER-9100 RLG Inertial Navigation System with a new integrated navigation sensor, it can match with an external GNSS receiver, the optimal design of multipath interference, under the condition of product in the GNSS auxiliary, it can reach high precision to maintain output for a longer time.

To meet the scalability requirements, ER-9100 RLG INS support odometer/DVL/barometric altimeter and other external sensors, using multi-sensor data fusion technology to inertial measurement with odometer/DVL/barometric altitude meter etc., combining can be realized for a long time and high precision integrated navigation, especially suitable for land-based applications such as high precision positioning directional and marine compass direction.
