Continuously Operating Reference Stations (CORS), is known as one of modern information infrastructures based on network, which enables users to obtain spatial data and geographic features in a dynamic, continuous, rapid and precise way. It serves mobile positioning, dynamic and continuous spatial reference frame, and geodynamics parameters, etc. As the major infrastructure for geodesic and space information services, it is widely used in the fields of surveying&mapping, transportation,and security. As the major part of CORS network, the base station (reference station) network consists of base stations distributed homogeneously within a certain range. It is responsible for collecting and transmitting the observations to a data processing center which also supply integrity monitoring services. One of the core parts of base stations is a high precision receiver. Unicore’s UR series base station receiver supports GPS, BDS, GLONASS and other satellite navigation systems. The receiver can provide millimeter-level carrier phase observations, have excellent low elevation signal tracking and multipath suppression capabilities, and supports rich peripheral interfaces such as network, external clock and 1PPS, as well as a simple and easy-to-use Web configuration interface, which is specially designed for CORS and ground-based augmentation system applications.

CORS applications
Unicore BDS base station receiver has been successfully applied to the first BDS foundation enhancement system demonstration project in Hubei Province, and other projects.
