Bolt miner multi-source information fusion positioning and orientation system based on inertial navigation

The invention discloses an inertial navigation-based multi-source information fusion positioning and orientation system for a bolter miner. The system comprises an inertial navigation module, an inertial navigation zero-speed correction module, a double-speedometer module, a millimeter wave radar ranging and positioning module, an information fusion module and an upper computer data management software resolving board, wherein the angular increment of a fiber-optic gyroscope and the speed increment of an accelerometer are respectively collected and resolved by the upper computer data management software resolving board, and the position, speed and attitude of equipment are output in real time; and the inertial navigation zero-speed correction module is used for judging whether the equipment is in a stopped state or not so as to carry out zero-speed filtering and estimating the constant offset of the inertial device in real time. Positioning and navigation are carried out based on information fusion of multipl
