| titleOfInvention | UUV cluster co-location system and method based on ranging and information interaction |
| abstract | The invention discloses a UUV cluster cooperative positioning system and method based on ranging and information interaction. The system of the present invention includes a master UUV, multiple slave UUVs, and a co-location device installed on the slave UUVs. The co-location device uses the INS data of the slave UUVs to perform position estimation as the main navigation unit, and uses acoustic ranging and co-location messages. Filter processing as a sub-navigation unit. The co-location method includes: master-slave UUV internal clock taming; the master UUV periodically packages its own position and position estimation covariance matrix into a co-location message, and broadcasts it to the slave UUVs of the cluster; receives the co-location message from the UUV; The co-location device constructs the state and measurement equations according to the data, and uses the extended Kalman filter to calculate the co-location result. The present invention considers the uncertainty of the position estimation of the master UUV itself, reconstructs the state vector of the slave UUV, and improves the overall positioning performance of the cluster. |
