FieldForce TCM-XB

PNI's FieldForce TCM-XB tilt-compensated compass module provides pinpoint accurate compass heading, pitch and roll readings over a wide variety of conditions. This includes anywhere GPS is compromised or unavailable – underwater, under bridges, under roofs, or underground.

Pinpoint accuracy...
The TCM-XB tilt-compensated digital compass provides industry-leading accuracy. It undergoes PNI's proprietary factory calibration to ensure absolute accuracy and utilizes PNI's SmartSens sensors to achieve high resolution. And the TCM-XB is designed with temperature and noise-stabilization so that it is inherently free of offset drift.

in real world conditions
Using PNI's advanced hard and soft iron calibration algorithms, magnetic anomalies encountered in the field can be accounted for, resulting in reliable and consistent heading readings. These are implemented using one of four user-selectable calibration modes, including a mode that allows for calibration simply in a horizontal plane. And, electronic gimballing means the TCM can be mounted in virtually any orientation. So the TCM performs well in the field, not just in the factory.

In real-world conditions, the TCM-XB delivers unmatched performance, making it ideal for applications such as dead-reckoning navigation, far target locating, AUVs, ROVs, object tracking, and more.
