Using GPS COG in place of heading for the NavNet 3

Question

​Is GPS COG - Course Over Ground information allowed for Heading and ARPA capability?

Solution

​No, while some radar systems allow GPS COG for Heading and ARPA functionality, Furuno believes that this capability is dangerous and not reliable, especially for ARPA calculations. NavNet 3D systems require actual Heading information at appropriate data rates (10Hz) for these functions.
