摘要: 为做好长三角卫星导航定位基准服务系统的互联互通,跨区域融合三省一市北斗地基增强系统资源,提升北斗位置服务支撑保障能力,本文研究了轻量化惰性格网和地理围栏技术,统一了跨区域差分数据格式,设计了区域一体化的北斗位置应用服务模型。通过浙江省卫星导航定位基准服务“政务一朵云”发布验证了轻量化惰性格网的高效性,并结合太湖西岸的跨区漫游实例验证了相关服务的有效性。

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
