The autopilot computer is the main unit in the Simrad AP24 and Simrad AP28 autopilot systems. This Simard AC42 course computer communicates on the proprietary SimNet data and control network to establish a reliable digital communication and power distribution between the units in the autopilot system as well as other Simrad products. SimNet provides high speed data transfer and control of Simrad products integrated in a total steering and navigation system. The model is compatible with hydraulic and mechanical steering systems.
The new compact Simrad AC42 autopilot computer is more powerful than ever and contains advanced software algorithms that are the brains of the system. These incorporate position and navigation data from the GPS chartplotter and wind, speed, and depth data from the instrument system. The output is a smooth proportional control of the rudder with the utmost precision, providing excellent steering performance in any sea condition.
