Product introduction TWXN-D04 is a dual-antenna split fiber optic gyro-integrated navigation product. The satellite navigation part integrates DTU, high-precision surveying and mapping-grade satellite receiving boards, and fiber-optic inertial measurement units including three-axis fiber-optic gyroscopes and three-axis accelerometers. They are precisely calibrated across the entire temperature range to meet the needs of different environments. performance requirements. Supports BDS, GPS, GLONASS, QZSS satellite navigation systems, and RTK positioning. It provides centimeter-level positioning accuracy and continuously and stably outputs attitude, heading, speed, position, and other information under various harsh environments such as satellite signal obstruction and multi-path interference. Features Support BDS/GPS/GLONASS/QZSS Centimeter-level high-precision RTK positioning, dual-antenna orientation, and support for integrated navigation Built-in high-performance optical fiber IMU, able to adapt to various usage environments Supports multiple differential data formats RTCM2.x/3.x CMR CMR+ High-level protection safety level IP67 Flexible and rich external interfaces, supporting serial port, Ethernet, CAN, USB 2.0, OTG, supporting TF card storage, etc. Integrated DTU supports 4G transmission (can support global network communication) Supports NTP, FTP file download, FTP push, and Email abnormality alarm Built-in web interface to realize board upgrade, configuration, control, and status query
