The JRC JLR-8400 is the compact, 2-unit sibling to the JLR-8600. It consists of a 4.5-inch display unit and a multi-constellation sensor. By processing signals from GPS, GLONASS, BeiDou, and QZSS at the same time, it provides stable and accurate positioning even in areas with limited satellite visibility or high signal interference.
Multi-GNSS Reception: Simultaneously tracks up to 22 satellites across GPS, GLONASS, BeiDou, and QZSS.
Arctic Ready: Specifically designed to maintain precise positioning in polar regions where SBAS and beacon signals may be unavailable.
Compact Design: The 4.5-inch display is ideal for smaller bridges or as a secondary navigation sensor on larger vessels.
IMO Approved: Fully compliant with international maritime standards for use as a primary navigation sensor.
Remote Maintenance: Supports remote system diagnostics and maintenance for increased operational uptime.
SBAS Correction: Automatically utilizes SBAS data to enhance position accuracy where available.
