JLR-21 GNSS COMPASS
The JLR-21 is an advanced GPS satellite compass that builds on the success of its predecessor, reaching a new level of performance and stability. Described as a "3D Dynamic Sensor™," this system not only provides directional information but also analyses the ship's movements along all axes with high accuracy.
Key Features
High Accuracy Direction Information
The JLR-21 provides heading information with an accuracy of 0.5° RMS. Its advanced sensor structure allows it to measure the ship's heading, position, and speed with high precision. Its fast and reliable data flow ensures safe navigation even in heavy maritime traffic.
3D Dynamic Sensor™ Technology
This JRC-exclusive technology precisely detects not only heading but also ship movements such as roll, pitch, heave and ROT (Rate of Turn). This ensures stable performance even in rough and challenging sea conditions.
Compact and Integrated Design
Because the processor is located within the antenna unit, it saves space and cables during installation. Its compact design makes it easy to integrate into all ship types, making maintenance and installation quite simple.
Advanced Visual Interface
The 5.7-inch high-brightness LCD display provides clear visibility even in low light. The backlit keypad and user-friendly menu structure ensure easy operation.
Satellite Security and Wide System Compatibility
It supports SBAS (WAAS/EGNOS/MSAS) and automatically checks the reliability of satellite data thanks to its RAIM feature. It can also easily connect to radar and other navigation devices using standard protocols such as NMEA 0183.
