Ideal for Demanding Applications
A compact, low-cost compass module, the KVH C100 supplies accurate heading data, whether as a stand-alone or integrated into other systems. Its rugged military-grade construction makes it versatile and reliable in extreme locations and environments. 

Suitable for Remote Mounting
Automatic compensation ensures the highest degree of accuracy from the C100, while menu-driven software control makes it possible to configure its output for use in other products. The C100 can also be connected to a PC for prototype testing. The mechanical design of the unhoused version of the unit permits one-piece mounting in simple installations; a detachable sensor element allows use in applications where space restrictions or sources of magnetic interference require remote mounting.

Data rates up to 10 Hz are available using the KVH C100 compass engine.


The KVH C100 compass engine offers both analog and digital outputs. In analog, linear DC voltage and sin/cos DC voltages are offered. In digital, several variations of RS-232 and NMEA 0183 are available.


The typical accuracy of the C100 compass engine after calibration is ± 0.5 degrees.

The C100 has a current drain of 25 mA.

The C100 compass engine will operate as far as 80 degrees north or south magnetic latitude. This limit is the result of the three-dimensional nature of the earth's magentic vector. Once you proceed higher than 80 degrees north or south, the vertical component of the vector starts to become greater than the horizontal and the compass will be unable to operate correctly.
