M5700 Maritime Survey-Grade Fiber Optic Gyro Strapdown Inertial Navigation System
M5700 optical fiber inertial navigation is mainly composed of integrated optical fiber gyroscope, quartz flexible accelerometer, power supply module, acquisition and calculation module, satellite navigation module, etc. It has the characteristics of small size, light weight and high accuracy, and is suitable for small and medium-sized UAVs, photoelectric pods, underwater carriers and other applications. The main features are as follows:
Has a high self-seeking north accuracy;
Pure inertia, inertia/satellite combination, inertia/DVL combination, inertia/mileage combination, inertia/vision combination, marine compass, etc.;
It has functions such as self-seeking north, transmission alignment, satellite-assisted moving base alignment, high-precision post-processing, and heave measurement;
Built-in shock absorber, can adapt to vibration environment;
Built-in memory card, capable of storing measurement data, which can be read by USB or network port;
Built-in multiple communication protocols, serial port baud rate, output protocol can be configured
Has multiple interfaces such as RS422, RS232, Ethernet, PPS input/output, etc.
Operating temperature: -45 ℃～+60 ℃
Power supply: 12V ~ 36V, power consumption < 15W
