The invention discloses a navigation information source group optimization interaction method for cross-domain collaborative navigation, which optimizes collaborative navigation information source selection of a to-be-assisted carrier, so that relative measurement and information interaction selection between the to-be-assisted carrier and a reference information source are more reasonable. A position error matrix is obtained by segmenting a to-be-assisted carrier covariance matrix, an error ellipsoid of an actual navigation position is solved according to the error matrix, and the axial length and direction of the error ellipsoid are obtained. According to the method, selection of a cooperative positioning signal source is optimized, the cooperative information calculation processing amount can be reduced, and cooperative positioning calculation is accelerated; the influence of signal source configuration and precision on a positioning result is considered, and the positioning precision is improved by efficiently utilizing cluster positioning information optimization. Compared with an optimized random signal source selection cooperative positioning algorithm, the method can effectively improve the cooperative positioning efficiency and precision in irregularly distributed clusters, and is suitable for practical application.

    本发明公开了一种用于跨域协同导航的导航信息源群优化交互方法,对待辅助载体的协同导航信息源选择进行了优化,使得待辅助载体与基准信息源间的相对测量及信息交互选择更加合理;通过分割待辅助载体协方差矩阵获取位置误差矩阵,根据误差矩阵求解实际导航位置的误差椭球,获取误差椭球的轴长和方向。本方法优化了协同定位信号源的选择,能够减少协同信息计算处理量,加快协同定位解算;考虑到信号源构型和精度对定位结果的影响,高效利用集群定位信息优化提高了定位精度。和未采用优化的随机信号源选择协同定位算法相比,本发明在不规则分布的集群中能有效提升协同定位效率和精度,适合实际应用。
