FOG INS/GNSS zGo - FC

zGo - FC is a strapdown inertial navigation system (SINS) based on precise Fiber Optic Gyroscopes (FOG) and high-performance quartz accelerometers. 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 excellent orientation and calculate the linear speeds of an object, its coordinates and altitude. The system has the ability to calculate the accurate position and orientation during GNSS outages. Additionally, the system can also determine the accurate initial value of heading (no need to use magnetic sensor signal at all). Moreover, the system has a set of various navigation algorithms proposed for different vehicles to achieve the best accuracy results.
