The THOR line is based on its predecessors – the Sigma, Titan and Falcon lines – and combines analogue and digital technologies in a versatile line of navigation products. The THOR line is suitable for both new construction and the replacement market.

THOR-500 Compact Autopilot

The THOR-500 is the compact autopilot of Radio Zeeland. This unit has a Rate of Turn indicator and rudder position indicator in the same housing. This makes the autopilot compact and easy to install. The THOR-500 works in combination with the THOR-650 steering lever. This autopilot is used when the room for installation in the wheel house is limited. The THOR-650 steering levers are small enough to fit into the arm rest of your seat, contributing to a flexible and user-friendly system.


Like the THOR-550, the THOR-500 is connected to the junction box P-503, which is connected to the sensors P-100 and P-300 for bend speed and rudder position indication.
