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.

Integrated System and Flexibility

The JRC JLR-21 GPS Satellite Compass is designed for perfect compatibility with marine systems. Its extensive connectivity options and compatibility make it easy to integrate with your existing navigation systems.

Main Integration Features:

NMEA 0183 and IEC61162-1 compatibility:
The JLR-21 provides seamless integration with existing radars, chartplotters, and other navigation devices. It is compatible with NMEA 0183 and IEC61162 protocols, simplifying data sharing.
SBAS and RAIM Support:
It automatically monitors satellite positioning reliability. SBAS (WAAS, EGNOS, MSAS) correction signals increase accuracy, while the RAIM function continuously monitors system security and accuracy.
Effective Data Sharing:
The system continuously updates COG, SOG, Heading, and ROT data and shares it with connected devices. This feature ensures consistent processing of data from ship navigation instruments.
Easy Integrated Installation:
The integrated antenna and processor unit structure simplifies installation. Furthermore, the integrated processor eliminates the need for a separate processor box, reducing cable clutter.
Adaptive Performance:
The JLR-21 offers flexible use for a variety of maritime applications. Whether commercial vessels, private yachts or military platforms, the system adapts to all types of maritime platforms.
