Sub-1° accuracy in real-world conditions

Digital Magnetic Compass TCM-XB & TCM-MB

For applications that require consistency and accurate heading, pitch and roll in all latitudes globally, TCM-XB and TCM-MB are high-performance, low-power consumption, tilt-compensated electronic 6-axis digital compass modules with 0.3° RMS heading accuracy.

 

Z

PNI’s TCM was the first electronically tilt compensated compass to replace gimbled flux gate compasses that only worked when level. PNI pioneered the first digital magnetic compass that worked in real-world conditions and Its reliability has been field tested for over 20 years.

Z

Two form factors are available — the TCM-MB offers the same features and accuracy as the TCM-XB in a smaller footprint with TTL output.

Z

Unlike other digital magnetic compasses, TCM-XB and TCM-MB with PNI’s high sensitivity magnetic sensors provides accurate heading even at high latitudes where magnetic compassing signals are small, making accurate determination of heading difficult.
