You can get correction data for Network RTK positioning (such as VRS and Single Base) from mount points on Pivot Platform.
The typical precision within 20 km around the CORS would be 3 cm in horizontal, and 5 cm in vertical (standard deviation), which may change according to time, conditions and location.
You can also get GNSS observation data collected at each CORS in a standard format named RINEX.
The RINEX data can be used as your fixed point for static GNSS surveys
Currently the coordinate system used in Khmer GEONET is Cambodia Geodetic Datum 2009 (CGD09). This is a realization of ITRF2005(Epoch 2009.56). When the latest ITRF2020 becomes available, we will provide CGD22 coordinates in ITRF2020 and transformation parameters
