Main Features

Single-unit design with a control and display unit featuring a 4-digit heading display and 6 operating keys.
Heading accuracy: Static ≤ 0.1° secant latitude, Dynamic ≤ 0.4° secant latitude.
Automatic static north speed error correction.
High-speed transmission and follow-up system at 100°/sec.
Self-aligning repeater compasses with serial interface IEC-61162-1 / RS 422.
Twin rotors and liquid damping system to eliminate latitude error.
Monitoring and alarm functions for voltages, gyroscope current, and follow-up system.

Inputs and Outputs
The system supports multiple inputs and outputs, including:

Inputs: Position, speed, heading from electronic compass, and alarm mute.
Outputs: NMEA TTL, RS 422, IEC 61162-1, Furuno AD10, and rate of turn outputs.

Power and Consumption
Main and backup power supply ranges from 18 VDC to 36 VDC. Power consumption is 80 W at start-up and 45 W during operation.

Dimensions and Weight
The system measures 404 mm in width, 520 mm in height, and 420 mm in depth, with a weight of 25 kg.
