zGo - MA is an ultra compact size strapdown inertial navigation system (SINS) based on MEMS gyroscopes and MEMS accelerometers. The system has unique internal MEMS sensors’ temperature stabilization system, providing an excellent system accuracy for a wide temperature range. The system has internal high-frequency GNSS receiver (GPS, GLONASS, SBAS, Galileo and Beidou) and barometrical sensor. The combination of sensors data and the GNSS information allows the system to provide robust orientation and calculate the linear speeds of an object, its coordinates and altitude. The system has the ability to calculate the robust position and orientation during short time GNSS outages. Additionally, the system has a set of various navigation algorithms proposed for different vehicles to achieve the best accuracy results.
