Overview

BTSTC-0440S integrated navigation system is based on three-axis fiber optic gyroscope, quartz flexible accelerometer and high-precision satellite positioning device. It realize high-precision measurement of attitude, velocity and position of moving carrier, which can be widely used in navigation and attitude measurement of various aircraft, vehicles and ships.

Composition

• Fiber optic gyroscope

• Quartz flexible acceleration, navigation computer

• Satellite navigation receiver

• satellite signal receiving antenna

• 2 GNSS measurement antennas and 2connecting wires
