Autopilot System · Autopilot & Bridge Systems
The Robertson (Simrad) AP9 MK3 is a legacy analog autopilot system that uses PID control to maintain heading, primarily designed for small‑to‑medium workboats and fishing vessels. As an Autopilot, it is normally installed on the bridge with the required external sensors, antennas, displays and data-network interfaces. In that role, its primary purpose is to provide navigation, position, heading, speed, depth, traffic or bridge-management information according to the listed category. Radar, ECDIS, gyrocompass, GNSS, speed log, echo sounder and integrated bridge systems use different sensing principles, so calibration and interfaces must match the actual installed equipment. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
