Heading Sensors - Electronic 3-Axis Compass Modules - TCM-XB & TCM-MB


Sub 1º Accuracy in Real World Conditions

TCM 5LT Electronic Module

Provides pinpoint-accurate pitch, roll and compass heading in real-world conditions, performing reliably and repeatably in the field — not just in the factory.

Where GPS is compromised or unavailable — whether underwater or underground, beneath a bridge or inside a building — PNI’s FieldForce® TCM tilt-compensated compass modules provide reliable, pinpoint-accurate pitch, roll and compass heading.

The TCMs use advanced algorithms to counter the effects of hard and soft iron interference, providing highly accurate heading information in most any environment and any orientation. PNI’s patented magneto-inductive sensors and pioneering measurement technology combine to provide all this performance under a low power budget that extends mission duration

The TCMs’ unmatched performance in real-world conditions makes them ideal for applications that require consistency and accuracy in the field — far target location, object tracking, and more.

TCM XB Electronic Compass Module


Sub 1° accuracy...

The TCM is a high-performance, low power consumption, tilt-compensated electronic compass module that provides industry-leading heading accuracy.  The TCM combines PNI's patented 3-axis geomagnetic sensors and 6-axis MEMS accelerometer with PNI's proprietary factory calibration algorithms to ensure absolute accuracy.


...in real world conditions.

PNI recognises 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. Applications may have physical constraints for doing calibration, the TCM provides 4 different calibration methods, 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 latitudes where the dip angle (inclination) limits the usefulness of other compasses. So the TCM performs well in the field, not just in the factory.
