Abstract:

Employing radar or optical equipment to carry out tracking measurements with regard to spacecraft, it is possible to obtain observation data associated with ranges and their rates of change. Due to causes in many areas such as measurement equipment precision, environmental conditions, and so on, these measurement data include errors in all cases. Besides random errors associated with range finding and range change rates, there are also systemic errors associated with range finding. Through the setting up of appropriate mathematical models, spline functions and regression analysis methods are employed to give a type of method for estimating range, range rate, and range finding system errors. The methods in question are very easy to realize and calculate. Theoretical analysis and simulation calculations clearly show that the methods in question possess very high accuracy.
