- GPS/GNSS Compass
Features
Display Unit
The new GNSS Compass JLR-41 is a heading sensor that uses GNSS (Global Navigation Satellite System) to determine the ship‘s heading. The Sensor is more accurate and smaller than our previous JLR-21 sensor.
Sensor
Multi-GNSS Sensor
The newly designed multi-GNSS sensor can simultaneously receive GPS, Galileo, GLONASS, BeiDou, and QZSS data, enabling highly accurate positioning without the use of beacons or SBAS, thereby ehhancing orientation performance.
Spoofing/jamming Detection Function
JLR-41 is equipped with a spoofing/jamming countermeasure function*3. When spoofing/jamming is detected, users are notified via pop-up, icon, and buzzer. Furthermore, satellite signals affected by spoofing/jamming are excluded to maintain accurate positioning*4. This contributes to safe and secure navigation
Furthermore, SSV can be used to monitor spoofing/jamming occurrence status from shore.

*3: A separate license is required to enable the spoofing/jamming detection function.
*4: If few satellites are unaffected by spoofing/jamming, positioning may not be possible.
Supports Rolling, Pitching, Rate of Turn and Heaving Measurements
Heaving measurement relatively measures the vertical displacement of the ship caused by waves and swells.
Rolling and pitching measurements are used to measure the ship's lateral and longitudinal movements.
By inputting the measurement data into fish finder or other device equipped with stabilizer function, the detection accuracy of fish schools and seabed topography can be improved.
The rate of turn (ROT) has a maximum follow-up angular velocity of 45°per second, enabling stable tracking even during high-speed turns.
