The conditons necessary for the exitence of a unique soluion to these equaions ae discssed, and the solutions to a numer of POLYDOP sysem equons are presented. The problems tha appear when more than one vehicle is in the region of observation of the system at any given tme are discussed. SITUATIONS ARE CONSDERED IN WHICH THE SAME DATA MIGHT BE TAKEN EVEN IF THE VEHICLE PAHS CORESPONDNG TO THIS DTA ARE NOT THE SAME. The problem of conversion of range information into Catesian coordinate information i treated. The two most common measures of eror propagaton and a method for finding the point of interection of two conics are included. Author
