[CA11] Specs for rate gyro for old Autohelm type 300 computer
Hello,

unfortunately I'm not able to get one of the old Autohelm rate gyro's for my type 300 unit. I just decided to build my own which is actually not that difficult. I know that the rate gyro outputs a signal of +/- 25mV °/sec to the input of the autopilot and that is a 80°/sec type of sensor.

The questions I have are:
Will the voltage increase or decrease while I turn to port?
In addition to the rate gyro the pilot is also equipped with an input for a roll gyro. Will adding a roll gyro further improve the steering performance?

Greetings Onyx

Welcome to the Raymarine Forum Onyx,

Unfortunately, the Type 100/300 Autopilot Course Computer is exclusively and supported for use with Raymarine's Pathfinder Smart Heading System. No other rate gyros are supported for use with this product. Raymarine has not released the specs of the rate gyro feature within the Pathfinder Smart Heading System.
