Abstract:	The concept and algorithm of “Ship’s Heading Integrity” were proposed by the authors in last IAIN World Congress in Prague. Ship’s Heading is one of the most important Navigational Information and it is essential to make a good integrity automatically to execute a safety and efficient navigation. The proposed concept and algorithm is ship’s heading integrity to detect the differences between same or different types of plural compasses called “multi-compass”, and simulation of compass movement and ship motion were executed to evaluate the performance of integrity. Following by the prior study, the authors proceeded to survey the performance and validity of integrity system monitoring the differences in frequency domain using multi compass with onboard observation. It was confirmed that CAIM (Compass Autonomous Integrity Monitoring) comes in for easy to detect the malfunction of compass and compass error, and expected to make a safety and efficient/effective navigation.
