Abstract
In this contribution, we study the models of BDS/GPS combined in three different fields relative positioning, which contain field of coordinate estimates, field of normal equations and that of observation equations. The precision of coordinate solution, differences and similarities in different fields are discussed. On the condition of single epoch and static sequential Least-squares calculation, combination of normal equation field and that of observation equation field are with equivalence, while on the condition of dynamic calculation, the combination of observations equation field is more rigorous than that of normal equation field, and the Ratio rate of the integer ambiguity estimates is higher. Based on the data from measured short-baseline, we verify inference given in the contribution by experiment and analyze through calculation on single epoch, sequential Least-squares and dynamic.
