Product Description

TCM-MB 3-Axis Compass Module

Where GPS is compromised or unavailable — whether underwater or underground, beneath a bridge or inside a building — PNI's TCM tilt-compensated 3-axis compass module provides reliable, pinpoint-accurate pitch, roll and compass heading. The TCM uses advanced algorithms to counter the effects of hard and soft iron distortiions in the host system, providing highly accurate heading information in most any environment and any orientation. PNI's patented geomagnetic sensors and pioneering measurement technology combine to provide all this performance under a low-power budget that extends mission duration. The TCM's unmatched performance in real-world conditions makes it ideal for applications that require consistency and accuracy in the field — dead-reckoning navigation, far-target location, AUV and ROV navigation, object tracking, range finding, seismic monitoring and more.

Sub 1° accuracy

The TCM is a high-performance, low power consumption, tilt-compensated compass module that provides industry-leading heading accuracy. The TCM combines PNI's patented geomagnetic sensors and 3-axis MEMS accelerometer with PNI's proprietary factory calibration algorithms to ensure absolute accuracy.

Real world conditions

PNI recognizes there's a difference between performing well in the factory and perfoming well in the field. The TCM's advanced field calibration algorithms account for these differences by correcting for local magnetic distortions. And since applications may have physical constraints for doing calibration, the TCM provides four user-selectable calibration modes, as well as the ability to recalibrate the accelerometers to ensure long-term accuracy. The TCM's measurement technology inherently ensures the module is free from offset drift and provides high measurement resolution, which is critically important at high and low lattitudes where the dip angle (inclination) limits the usefulness of other compasses. So the TCM performs well in the field, not just in the factory.
