Functional Description
slave unit) and one 12 channel with built-in beacon (operating as a
master unit) with one GPS and Loop (H-Field) combined Discus style
antenna. It is capable of receiving DGPS corrections in the RTCM
SC-104 version 2 format via one of the four input data ports, or via
its internal marine beacon DGPS receiver. This configuration allows
data to be shared between two remotely separated stations (i.e.
navigator’s station and helmsman’s station), with independent
access to various information fields. The 6 channel GPS gets its
positioning information from the 12 channel with the built-in beacon,
but can be connected to the antenna independently and calculate its
own position as a back-up GPS receiver.
12 Channel Dual Control Integrity Monitor
This is an enhanced to the 12 Channel Dual Control configuration. It
is a dual control DGPS system where two DGPS receivers are
supplied, one 12 channel with built-in beacon (operating as a slave
unit) and one 12 channel with built-in beacon (operating as a master
unit) with two GPS and Loop (H-Field) combined Discus style
antennas. It is capable of receiving DGPS corrections in the RTCM
SC-104 version 2 format via one of the four input data ports, or via
its internal marine beacon DGPS receiver. This configuration allows
data to be shared between two remotely separated stations (i.e.
navigator’s station and helmsman’s station), with independent
access to various information fields. The purpose of this configuration is for each receiver to calculate its own position, then to check
the operational status of the other GPS receiver. The GPS receiver
with the best overall operational status then provides the system
position. This provides a fully redundant system, with self-recovery
capabilities. The Integrity Monitor function can be set to Automatic
switchover, forced to the Master unit, or forced to the Slave unit for
position and navigation functions.
The Installation & Service Manual has more details on the parts
supplied with each configuration, and their associated part numbers.
Beyond the physical differences between these models, the operating software is exactly the same, except where the hardware differences mentioned above come into play. Expect to find these differences detailed in the GPS, DGPS, & CFG sections of the manual.
