[CA] [CA11] AIS integration with GPS

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum pressonjh,

Q1. Is it still necessary to install the AIS650 with a separate GPS antennae?
A1. Yes. Class B AIS transceivers are exclusively dependent upon their own internal GPS receiver to determine the vessel's position, COG, SOG, date, and time. The internal GPS receiver in these Class B AIS transceiver are often (and in the case of Raymarine's Class B AIS transceivers) dependent upon an external GPS antenna (not to be confused with an external GPS sensor (ex. Raystar 130, Raystar 150, AR200, etc.) to supply GPS signal to the Class B AIS receiver's internal GPS receiver.

Q2. If so, does this new GPS unit antennae need to be installed within sky sight?
A2. Raymarine's external GPS antennas and external GPS receivers are designed to be installed in a location affording them an unobstructed view of the skies overhead.
