The invention relates to a tunnel navigation pseudo-satellite geometric configuration deployment method, which comprises the following steps of: determining an effective coverage area of a transmitted signal of a deployed single pseudo-satellite according to a receiving dynamic range of a user terminal receiver; 1/4 length is taken as the deployment spacing of the cross sections of the adjacent pseudo satellite tunnels; expanding the vertical deployment space of the pseudo satellites along the height of the tunnel, and uniformly deploying a multi-layer height plane; the height positions are deployed in a pairwise staggered combination mode, a plurality of pseudo-satellite placement groups are formed, and each group comprises two pseudo-satellites; forming a tunnel pseudo-satellite layout scheme of a similar double-helix structure; the pseudo satellite groups are sequentially installed according to the deployment spacing, so that the whole tunnel completes signal coverage of the whole area; generating a tunnel pseudo-satellite layout scheme of multiple types of double-helix structures; and selecting an optimal tunnel pseudo satellite deployment scheme. On the premise that the number of the observable pseudo satellites in the whole area meets the positioning calculation requirement, the method has the advantages of being simple in layout and easy to operate.

    一种隧道导航的伪卫星几何构型布署方法,包括:根据用户终端接收机的接受动态范围,确定所部署的单个伪卫星的发射信号有效覆盖区域;取四分之一长度作为相邻伪卫星隧道横截面部署间距;沿隧道高度拓展伪卫星的垂直部署空间,均匀部署的多层高度平面;两两交错组合部署高度位置,形成多个伪卫星放置组,每组含两个伪卫星;形成类双螺旋结构的隧道伪卫星布设方案;根据部署间距依次安装伪卫星组,使整个隧道完成全体区域的信号覆盖;产生多种类双螺旋结构的隧道伪卫星布设方案;选择最优的隧道伪卫星部署方案。本发明在全区域可观测的伪卫星数量满足定位解算要求的前提下,且具有布设简单易操作的特点。
