The SI-FINS90S is a standalone fixed inertial navigation system equipped with versatile configuration interfaces. It supports access to both built-in and external GPS modules and can be seamlessly integrated with the Hexin Xingtong UM982 high-precision GNSS receiver.
The integrated GNSS receiver features up to 220 channels and multi-frequency signal reception. It performs high-precision position, velocity and time (PVT) calculation to ensure reliable navigation output. Supporting abundant frequency points, the receiver is compatible with GPS L1/L2/L5, BDS B1I/B2I/B3I, and GLONASS G1/G2 satellite signals.
To suppress inertial sensor errors and further improve navigation accuracy, the SI-FINS90S reserves multiple external correction input interfaces, including DMI (Distance Measuring Instrument), DVL (Doppler Velocity Log) and barometric altimeter. In addition, GPS data can be imported via serial port for auxiliary calibration.
