Reference Base Station (GNSS)

Reference base station for differential correction of data collected with global satellite navigation system (GNSS) devices

What does this tool offer?

The GNSS base station is located at a fixed point with precise geographical coordinates. It provides reliable information for different calculations and surveys of geodetic control, data collection for Geographic Information Systems (GIS) and photogrammetric surveys of terrestrial type, among other utilities. It records the data of the geographic coordinates during the 24 hours of the day and publishes them on the web every hour in intervals of one second (RINEX format).

Users of mobile GNSS can use the data from the fixed station to make the differential correction of the geographic coordinates recorded with portable equipment.
