Based on the analysis about the development of attitude determination, Least-Square Ambiguity Decorrelation Adjustment(LAMBDA), which is a method of ambiguity resolution in real time, is made further study. The thesis presents detailed theoretical analysis, formula derivation and example verification for sequential conditional Least-Squares estimation and ambiguity decorrelation, and the simulations of search space before and after decorrelation and comparison of variance based on the ambiguity are verified. All these researches can provide technology reference for the future development of attitude determination.
Key words: LAMBDA; ambiguity; attitude determination
