Meaning
Advanced Steering Technology (AST) is Raymarine's unique advanced steering
algorithm. It uses inputs from a wide variety of sensors to tune the autopilot's
operation to provide superior control of the boat in any condition.
Self-learning calibration feature available on S1G, S2G and S3G autopilot sys-
tems.
The AutoTrim setting determines the rate at which the autopilot applies 'stand-
ing helm' to correct for trim changes caused by varying wind loads on the sails
or superstructure.
American Wire Gauge.
Marked on Raymarine products that comply with defined European Commu-
nity standards.
Counter rudder is the amount of rudder the autopilot applies to try to prevent
the boat from yawing off course. Higher counter rudder settings result in more
rudder being applied.
Constant Running hydraulic pump.
Direct current.
When powered up, all electrical equipment produces electromagnetic fields.
These can cause adjacent pieces of electrical equipment to interact with one
another, and this can degrade their performance. By following the EMC guide-
lines in this handbook, you can minimize these effects by ensuring optimum
Electromagnetic Compatibility (EMC) between equipment.
Standard Raymarine compass supplied with course computer core pack.
Global Positioning System.
Raymarine's GyroPlus yaw sensor that measures the boat's rate of turn. It is
built into the S1G, S2G and S3G course computers.
Inboard/Outboard or stern drive.
Man overboard.
Nautical mile.
