Key Features

Dual GNSS Antenna Structure

The SCX-21, with its dual antenna structure, provides ±1° static heading accuracy. This ensures stable navigation systems and accurate vessel heading.

GNSS-Based Multi-Directional Data Generation

It produces not only direction data but also pitch, roll, heave, ROT, SOG, and COG data. A wide range of motion and position data can be obtained with a single device.

Compact and Lightweight Design

The SCX-21 can be easily installed in small spaces, weighing approximately 1 kg. This makes it suitable for use even on boats with limited space.

 

Compatibility with Radar and Autopilots

Heading data ensures stable radar images. It also integrates with autopilot systems like NAVpilot to provide more stable directional control.

Easy Integration with NMEA 0183 Output

It can be easily connected to existing navigation and communication systems thanks to its standard NMEA 0183 interface.
