MEMS Accelerometer

I6700

I6700 SERIES is MEMS integrated navigation system uses high-precision gyroscopes, accelerometers, magnetic sensors, temperature sensors, barometers, satellite receivers, and other sensors, which can replace advanced products with similar performance in Europe and America, as well as fiber optic integrated navigation products with equivalent accuracy. Customized services can be provided according to user needs. At the same time, it can receive satellite differential system reference station information and use high-performance navigation algorithms to fuse multi-sensor information. It can output high-precision navigation information such as pitch, roll, heading, speed, position, etc. of the carrier, suitable for vehicles, aircraft, robots, surface vehicles and other carriers. In the most challenging environment, it can provide very superior attitude and navigation data.
