Strapdown Inertial Navigation System
Nav-5

SINS Nav-5 is strapdown inertial navigation system designed for railways applications. SINS Nav-5 is based on fiber-optic gyros (FOG) and quartz accelerometers. The system provides continuous determination and output of position coordinates, motion parameters and attitude angles.

SINS Nav-5 incorporates satellite navigation system receiver (GPS or GPS/GLONASS per customer choice). System is compatible with any type of GNSS receiver, capable of NMEA 0183 data output.

To enhance accuracy characteristics in autonomous inertial mode the system can acquire data from external odometer sensor.
