Continuously Operating Reference Stations (CORS): The reference stations are equipped with GNSS receivers and Choke-ring antennas to collect GNSS raw data (Carrier Phase and Pseudorange Code).

Uninterruptible Power Supply (UPS) are installed at each of the CORS to ensure the GNSS receivers can work continuously even with power failure. The routers will transfer the GNSS data, meteorological observation and tilt data to the SatRef Data Centre.

SatRef Data Centre: The Data Centre is used to process data collected from CORS in a high availability infrastructure and provide services to users via internet.

SatRef Control Centre: The Control Centre is used to monitor the operation of the whole SatRef system, the GNSS data status, quantitative and qualitative control of both products and services, etc.
