摘　　要：在协同作战领域,相对导航技术是实现高精度时空统一的重要途径。本文对基于载波相位和伪距的单差与双差相对导航方法进行了深入的研究和分析,建立了双差算法模型以及相对定位解算模型,开发了卫星导航差分相对定位处理软件,进行了零基线和短基线的静态相对定位试验。试验结果表明:采用双差伪距测量值的相对定位方法,能够获得小于2m(1σ)的定位精度。In cooperative engagement field,relative navigation technology is an impor-tant method of realizing the space-time unify of high accuracy.In this paper,single-differen-tial and double-differential relative navigation algorithms based on carrier phase and pseudo range are discussed and analyzed in depth.Double-differential algorithms model and relative positioning solving model are established,and a satellite navigation processing software is developed.Static relative positioning experiments with zero and short baseline have been done,and the results show that 2 meter of positioning accuracy can be obtained by using double-differential relative positioning method based on pseudo range measurement.
