USV/UUV Cooperative Navigation Algorithm Based on Moving Long Baseline and Navigation Error Correction

水下无人系统学报
Unmanned undersea vehicles(UUVs) undergo a cumulative increase of inertial navigation error caused by long-term cooperative movement. In order to reduce the relative navigation errors between unmanned surface vessels(USVs) and UUVs and improve the ...
