The Continuously Operating Reference System (CORS) is one of the modern information infrastructures based on the dynamic, continuous, fast and high-precision network to acquire spatial data and geographical features. CORS RTK can provide services for mobile positioning, the construction of dynamic and continuous spatial reference frame, and the determination of geodynamic parameters. As an important infrastructure providing geodetic and geospatial information, GPS CORS is widely used in various industries and fields such as surveying and mapping, transportation, security, and location-based services.
As the key part of the CORS RTK, the reference stations are evenly distributed in the coverage area. They are responsible for collecting GNSS satellite observations and transmitting them to the data processing center, as well as providing system integrity monitoring service. One of the core components of the reference station is the high-precision reference station receiver.
Unicore's UB-series boards support multiple satellite navigation systems including GPS, BDS, GLONASS and Galileo, and can provide millimeter-level carrier phase observations, with excellent signal tracking capability under low elevation angle and multi-path suppression capability. Unicore products also provide plenty of peripheral interfaces such as network, external clock, and 1PPS, as well as concise and easy-to-use Web configuration interface, which is particularly designed for CORS application.
