G620INS-232/CAN
Smart Antenna
The A&I G620INS-232 is a highly integrated GNSS/INS all-in-one unit,combining the GNSS antenna, GNSS module, and IMU module into a single structure,making the product easier to install and more reliable in performance.
Features
L1 Frequency GNSS Reception Compatible with Multiple Systems
Supports multi-constellation L1 band signals including GPS L1, BeiDou B1, Galileo E1, QZSS L1, and GLONASS G1, enhancing positioning reliability and coverage.
High-Precision Positioning and Speed Measurement Capability
Offers 1.5-meter CEP horizontal positioning accuracy and 0.3m/s CEP ground speed accuracy, meeting the requirements of high-dynamic and high-precision navigation.
Robust Inertial Assistance and Anti-Jamming Performance
Supports automatic inertial navigation positioning in the absence of GNSS signals, with multipath signal detection and interference suppression capabilities, ensuring continuous navigation in complex environments.
High Sensitivity and Standardized Communication Protocol
Equipped with a built-in high-gain LNA, offering sensitivity up to -165 dBm; the default baud rate is 115200 bps, supporting the NMEA-0183 standard protocol for easy system integration and data parsing.
