Abstract

Abstract: In order to realize the interconnection and interoperability of the satellite navigation and positioning reference service in the Yangtze River Delta, integrate the resource of BDS augmentation system in three provinces and one municipality, improve BDS service in support capability.This paper studies the technology of lightweight lazy grid and geofencing, designs a unified cross-region differential data format, proposes a regional integrated BDS application service model. ZJCORS service is released by “E-government-cloud”, which verifies the efficiency, and take an example of cross-regional operation in the west bank of Taihu lake to verifie the effectiveness of the service.

Key words: satellite navigation and positioning reference services, differential positioning, virtual grid reference station, geofencing, differential data fusion
