Collaborative Navigation Algorithm of One Single Datum Node Based on Network Adjustment
LI Jing
Abstract：Collaborative navigation algorithm of one single datum node based on network adjustment is proposed,aiming at the issue that satellite navigation of manned/unmanned vehicle cluster is susceptible to be interfered or suppressed.Based on the po-sition of available GNSS navigation,the incremental position of the inertial navigation/Doppler log integration,and the mutual dis-tance measurement between different nodes,a network adjustment algorithm is used to estimate the position of each node in the clus-ter,in order to provide high-precision position for the inertial navigation correction.It is completed that absolute position is estimat-ed for manned/unmanned vehicle clusters when only one node obtains satellite navigation information.Finally,numerical simulation experiments are conducted to verify the effectiveness of the algorithm proposed in this paper.
