摘要

The nominal accuracy of PDA GPS is ±10m, however, the results of experiment show that its practical absolute positioning accuracy is approximately ±80m and its stability of real-time positioning is ±30m. In addition, the positioning accuracy can reach about ±5m in 5 minutes. The main factors of position error are systematic error and gross error. The observation condition is the root of gross error, like unsatisfactory satellite intervisibility condition. While atmospheric delay of the GPS positioning satellite and positioning signal cause the systematic error. The key contents of this paper are the relations between the PDA GPS positioning accuracy and observation hours, the differentiation theory of different errors and their correction models.
