Yun Wu · Acta Geodaetica et Cartographica Sinica · 2011
Structure of the Compass is analyzed.Then the system′s visibility,DOP value and position accuracy in China mainland are simulated and analyzed.According to the features of the system′s constellation and referring the principle of space-based augmentation system′s integrity algorithm,the XPL value which the system can provide in China mainland is analyzed.The conclusion shows that the Compass can provide the integrity of APV-Ⅰin China mainland under a single frequency.
