Studies on construction of real time kinematic inspection field based on geographic information and remote sensing technology

Continuously Operating Reference Station (CORS) is an integrated service system constructed based on multi-base station network Real Time Kinematic (RTK) technology. CORS system is composed of several fixed and continuously operating GNSS reference stations which form a network automatically providing different types of GNSS observations such as carrier phase and pseudorange, various correction numbers, status information and other GNSS services through computers, data communication and Internet (LAN/WAN) technology. This article selects an appropriate location and sets up a reference station to receive Beidou, GPS, GLONASS satellite data basing on CORS system, establishes an All-Terrain inspection field, designs a set of mobile positioning terminals, and develops a set of real time inspection software for the calibration of navigation products. Experimental verification results shows that the calibration system designed by this article is applicable to calibrate navigation products and worthy of extensive promotion.
