Paper Abstract

On account of the uncertain factors caused by the uneven performance and precision of the measurement equipment, the complex and changeable environment and climate for flight in optical tracking measurement in space TT&C networks, the paper presents a method using the variance theory to evaluate the dynamic uncertainty of single optical measured exterior trajectory parameters, in order to figure out the transmission sensitivity coefficients of uncertainty, and to fuse trajectory parameters according to the uncertainty transmission law. The calculation and analysis based on actual combat mission data showed that the method can implement data fusion in trajectory layer. And the method had been proved in practical applications. This method not only expands the technique of comprehensive data processing but also provides technical support for the use of decision-making data.
