| Abstract: | In this paper,a direct soltion method to determine the 3-D coordinates of the unknown point by three observed distances is presented,which doesn't require initial values,iteration and multi-values judgment,and is suitable for computer programming.A practical formula of accuracy estimate is also introduced,which can be easily used to calculate the 3-D position precition by three observed distances.Through discussion of the application condition of this network,some suggestions about inclined angles limits are proposed,which possess important signification for practical jobs. |
