摘要
Methods and apparatus are disclosed for determining the positions of fixed reference objects for use in controlling the movement of mobile surface transportation units over a surface. The method includes detecting bearings from a measuring point on a mobile apparatus to the reference objects at predetermined times associated with movement of the mobile apparatus over the surface, storing the bearings along with the predetermined time associated therewith, and continuously computing the position of the reference objects and the degree of uncertainty associated with those positions from the bearings whereby the degree of uncertainty is reduced as the mobile apparatus moves over the surface.
