Self-Identification Method and Application of Measuring Equipment under Conditions of Close Arrange Stations

Abstract:

An effective method to improve and self-identify equipment measured precision is the method of error model best estimate of trajectory(EMBET).Under circumstances of several sets of photoelectric, radar equipment involved in measurement, correlation of error model coefficients was enhanced, accuracy of self-identification and orbit determination was dropped because of close arrange station. This paper uses a method of EMBET based on principal components estimate, and a method of screening method of optimal characteristic roots based on function of residual sum of squares to improve the efficiency of the characteristic root screening, the morbid phenomenon of matrix inversion was effectively eliminate, and the accuracy of self-identification and orbit determination was improved.
