Easy integration with a NovAtel SPAN-capable GNSS/INS receiver

The IMU-LN200 contains the Northrop Grumman LN200 IMU. The LN200 is a tactical grade IMU containing closed-loop fiber optic gyros and solid-state silicon accelerometers.


Advantages of UIMU-LN200

Low noise and stable accelerometer and gyro sensor biases make the IMU-LN200 an ideal choice for airborne mapping applications. IMU mounting is made easy by its small footprint. The IMU-LN200 is available as a complete assembly, including the IMU and environmentally sealed enclosure.

Improve SPAN LN200 accuracy

Take advantage of NovAtel CORRECT with RTK as well as support for satellite based augmentation systems such as L-Band or SBAS to improve real-time performance and accuracy. For more demanding applications, Inertial Explorer post-processing software from our Waypoint Product Group can be used to post-process SPAN LN200 data and offers the highest level of accuracy with the system.
