Accurate heading in any environment

TargetPoint TCM
IMU Digital Magnetic Compass

Proprietary magnetic anomaly rejection algorithms eliminate errors due to magnetic distortion, even in magnetically harsh environments.



An IMU digital compass that delivers high measurement resolution, critically important at high latitudes where the dip angle (inclination) limits usefulness of other compasses.


Low latency and no overshoot for quick target acquisition.


ITAR-free and made in the U.S.A.


Includes PNI’s magnetic sensor, state-of-the-art Low SWaP gyroscope, accelerometer and PNI’s 15 state Kalman filter sensor fusion algorithm that can be customized for your use-case.


Multiple calibration methods for ease-of-use and accuracy in a wide rage of applications – ideal for far-target locators, laser range finders and orientation for PNT.
