Advantages of IMU-CPT

Paired with NovAtel's OEM6 receiver, the IMU-CPT offers a fully integrated, tightly coupled GNSS and IMU system delivering the most satellite observations and the most accurate, continuous position, velocity and attitude solution possible. Further, the IMU-CPT is comprised entirely of commercial components, greatly minimizing cross border difficulties encountered with traditional GNSS+INS systems.

Improve IMU-CPT Accuracy

Take advantage of NovAtel CORRECT™ with RTK as well as support for other satellite based augementation 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® Products Group can be used to post-process IMU-CPT data and offers the highest level of accuracy with the system.
