Abstract

The invention discloses a vehicle-mounted positioning method based on multi-source information fusion, and the method comprises the following steps: 1, respectively obtaining the navigation information from each system; 2, carrying out the time-space registration of the navigation information from different systems; 3, carrying out the local filtering; 4, carrying out the information fusion; 5, outputting positioning information after information fusion, carrying out the reconfiguration of a main filter and a subfilter through an information distribution principle, and then returning to step 1. The invention innovatively provides the vehicle-mounted positioning method based on multi-source information fusion, and the method achieves the fusion of the position information provided by different positioning systems, improves the system redundancy, enables the positioning systems to complement each other's advantages, improves the dynamic adaptability of the systems, enables the total system to obtain the precision which is better than the precision of the local systems, improves the vehicle-mounted positioning capability, and enables a land-based weapon launching system to have the long-time and large-range maneuvering capability.

Description

technical field [0001] The present invention relates to the technical field of vehicle-mounted strapdown inertial navigation positioning and orientation, and more specifically, the present invention is a vehicle-mounted positioning method based on multi-source information fusion. Background technique [0002] At present, in order to improve the vehicle positioning system's ability to maintain long-term accuracy and adapt to complex environments, those skilled in the art have been looking for a high-precision, high-reliability positioning method. However, the existing single navigation and positioning system has inherent defects and cannot provide continuous and stable navigation information, and it cannot meet the requirements of the weapon launch system for long-term and large-scale maneuverability. For example, the satellite signal of the satellite navigation system is susceptible to interference and spoofing. The odometer system often has problems such as parameter drift,...
