An embodiment of the invention provides an inertial navigation positioning system based on UWB ranging. The inertial navigation positioning system comprises a UWB positioning base station, an absolute position determining base station, an inertial navigation positioning module and a cooperative positioning module, wherein the UWB positioning base station is arranged in a target positioning area and used for determining UWB relative positioning data of a to-be-positioned object by use of the relative position of the positioning base station determined by the communication interaction and arrangement way of a UWB label carried by the to-be-positioned object; the absolute position determining base station is arranged at the UWB positioning base station and used for determining the absolute position of the UWB positioning base station; the inertial navigation positioning module is carried by the to-be-positioned object and used for determining inertial navigation positioning data of the to-be-positioned object; the cooperative positioning module is carried by the to-be-positioned object and used for determining absolute positioning data of the to-be-positioned object according to the UWB relative positioning data, the inertial navigation positioning data and the relative position and corresponding absolute position of the UWB positioning base station. Through cooperative application of UWB positioning, absolute position base station and inertial navigation positioning technology, the absolute positioning data of the to-be-positioned object can be accurately obtained in a geographic area with relatively poor absolute positioning signal.
Description
technical field [0001] The invention relates to the technical field of inertial navigation and positioning, in particular to an inertial navigation and positioning system based on UWB ranging. Background technique [0002] At present, in the application of military exercises such as special police and armed police, the position and status information of individual soldiers in the long distance and indoors is a major focus of the backfield commanders. In order to realize real-time monitoring and command of combat personnel, the positioning system and its technology Higher level requirements are also raised. [0003] The inertial navigation system is a navigation parameter calculation system with gyroscopes and accelerometers as sensitive devices. The system establishes a navigation coordinate system based on the output of the gyroscope, and calculates the speed and position of the carrier in the navigation coordinate system based on the output of the accelerometer. Dead reck...
