AAQ GUI as part of the AvL AAQ Controller. The Vector Compass system uses GPS satellite information to produce an accurate heading without the need for an internal compass or manual compass setting.
2.3 Hardware Connection 2.3.1 Serial Communication Connection The Serial connection is prepared at the factory for connection of the Vector Compass to the Antenna connection bulkhead. Alternate connections are not an option for the hardware associated with this module. 2.3.2 Ethernet Communication Connection Ethernet connection is not an option for the hardware associated with this module.

4. Operation 4.1 Functional Overview A GPS based Vector Compass system is used as an alternative way to determine heading as opposed to using a magnetic device. As the GPS antenna is moved through space, its receiver periodically records position information. By using a second GPS unit at a measured distance from the first and comparing data between the two, positional errors can be mathematically eliminated.
Unless a secondary source is chosen, the default selection is the same as the primary. See the AAQ Controller Manual section for additional information on available heading sources. It is important to note that when the Vector Compass option is fitted, the standard compass as part of the NAV RIOM is generally omitted.
