High-Precision Position And Navigation System Sensor Output Pitch, Roll Heading 3 Axis Acceleration 3 Axis Gyro Value
INS-300 is a high-precision integrated navigation system independently developed by Avic group. It contains three self-developed 98 fiber optic gyroscopes, three quartz accelerometers, high-precision sampling circuit, navigation computer circuit, GNSS module and power supply circuit. And high-precision position and navigation in a complex environment are realized through multi-sensor fusion and an integrated navigation algorithm. The product has high reliability and strong environmental adaptability. The products can be widely used in intelligent driving, unmanned aerial vehicle, surveying and mapping, marine compass, stable platform, underwater vehicle, roadheader, mining machinery and other fields.
