摘要：This paper presents the analysis of PDOP factors for a ZigBee ground – based augmentation systems.It presents the idea of such a system followed by the results of assessment of application in Gdansk Marina.The results of the experiment show that the application of ZigBee can significantly improve PDOP value in harsh measurement environment.The analysis shows that it is possible to select an optimal location of ground-based transceiver on the basis of predicted trajectory and obstructions measured with laser scanning.
