Japan Radio Co., Ltd. will release GNSS Compass JLR-41 for safety navigation with multi-GNSS support, high-accuracy and stability.
Features
GNSS Compass JLR-41 is a device that determines the ship's heading by measuring the career phase difference between antennas using the carrier waves*1 of GNSS satellites. JLR-41 supports multi-GNSS*2 and increasing the number of satellites used for measurement, it can measure the heading with high-accuracy and stability. It is also equipped with a detection function against spoofing*3 and jamming*4, which have become issues in recent years as acts that obstruct navigation, contributing to safer navigation.
*1 Carrier Wave
The signal wave is a wave of electromagnetic waves or light used to transmit information such as sound, video, and data.
*2 Multi-GNSS
This is a technology that improves accuracy by simultaneously using multiple Global Navigation Satellite Systems (GNSS) to increase the number of received satellites, signals, and frequencies. GNSS includes GPS (United States), GLONASS (Russia), Galileo (Europe), BeiDou (China), and QZSS (Japan).
*3 Spoofing
Spoofing is a type of impersonation attack used as a method of cyber attacks. There is a risk of outputting incorrect positions and times by using fake GPS signals received from external sources for positioning.
*4 Jamming
Jamming is a type of interference wave in which an attacker or another device emits strong radio waves in the same frequency band as GPS signals. When subjected to jamming, the satellite signals in the corresponding frequency band cannot be received, resulting in the inability to perform positioning.
