Abstract

The invention relates to the field of navigation, and provides a universal integrated navigation system which comprises an integrated navigation module and a universal interface circuit. The integrated navigation module is at least used for completing inertial navigation calculation by utilizing the measurement data of the gyroscope and the accelerometer and completing integrated navigation calculation by combining the measurement data of the sensor. The integrated navigation module comprises a hardware layer and a software layer, and the hardware layer is connected with the universal interface circuit and supports operation of the software layer. The universal interface circuit is at least used for connecting sensors of different interface types and other system external devices. The universal interface circuit can be directly connected to sensors in most navigation related industries, and can be conveniently applied to airborne, vehicle-mounted, shipborne and underwater integrated navigation.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a general integrated navigation system and a general integrated navigation method. Background technique [0002] Modern commonly used navigation technologies mainly include inertial navigation, satellite navigation, astronomical navigation, radio navigation and so on. Among them, only inertial navigation is completely autonomous, neither radiating signals to the outside world nor receiving external signals. [0003] Inertial Navigation System (INS) relies only on the movement of gyroscopes and accelerometers in the inertial system to provide comprehensive navigation information around the world and around the clock. It is an independent and autonomous navigation technology. It has outstanding advantages such as continuous output of carrier position, velocity and attitude information, high short-term navigation accuracy, and complete independence. The inertial navigation system has bee...
