Improved method for intersection measurement with two photoelectric theodolites

A new method for locating target with two photoelectric theodolites is presented. The real-time calculation of the parameter accuracy was performed by the method based on the common locating formula. The weight coefficient is dynamically determined according to the accuracy variation of resolved ballistic parameters. The simulation result shows that the coordinate measurement accuracy is improved in the case of the intersection locating with two theodolites of different accuracy.
