| Abstract: | A GPS positioning and directional system with high precision and high performance / cost ratio is presented, where it applies the practical constraints to improve the estimation of Integer GPS Ambiguities based on the Least--squares Ambiguity Decorrelation Adjustment （LAMBDA）. Through the system engineering design, it has high accuracy, fast directional data output in practice. In a word, it can meet the user requirement under the overwhelming majority environment and reduce the system cost greatly. |
