Abstract :
The positioning precision of multilateration system is relevant with the location of remote stations which is reflected by dilution of precision (DOP). It is a common sense that adding a new station will improve the positioning precision because of the decreasing of DOP. However, nobody has declared the quality relationship between the number of stations and DOP. In this paper, we firstly analyze the DOP improvement quality range for a new station added. Also, we construct a model for the relationship between DOP and the number of stations. As a result, the user can decide to choose the number of remote stations according to the needed DOP through the model.
