Abstract
Accuracy Measurement on aerial track of moving target is one of the major target for photoelectric theodolite, which target is solved by angle intersection algorithm of two-stations. For analyzing the accuracy and the photoelectric theodolite of the angle intersection measurement, this paper simulated 6 aerocrafts’ tracks. L,K algorithms of coplanar rendezvous and MLE algorithms of non-uniplanar intersection were used to measure aerocrafts’ tracks. The measurement result was relative analyzed with simulation track in angle intersection, then the L,K ,MLE algorithm’s applicability was fixed. One aerocraft track of simulation was chosen to measure by MLE algorithm in different station-setting conditions. The measurement error was compared in intersection angle, azimuth angle, pitching angle, baseline length, station location. And the relation between the conditions and measurement accuracy of tracks was fixed. Also the condition of station-setting was fixed. The work above has directive significance in the intersection algorithm choice and station-setting later.

Measurement elements of optical equipment are teams of A, E, which is shorten as nAE. The nAE is belong to angle intersection measurement mechanism [1]. The optical equipment usually supplies angle information only, two-stations theodolites or n-station theodolites are used in solid intersection measurement, and spacial coordinate of aerocraft is fixed [2]. This method is called angle intersection measurement. This article simulated 4 aerocrafts tracks, and used 3 algorithms above to measure the tracks [3]. The measurement result was relative analyzed with simulation tracks in intersection angle, and the L, K, MLE algorithm’s applicability was fixed [4].

Usage of photoelectric theodolite faces the problem of station-setting, and the station-setting directly influences the measurement accuracy of track [5]. This article chooses one aerocraft track to measure by MLE algorithm in different condition of station-setting. The measurement error was relative analyzed in intersection angle, azimuth angle, pitching angle, baseline length and station location, by which the relation between measurement accuracy and 5 conditions was fixed. The condition of station-setting was fixed on the base.
