Note: These horizontal coordinates are equivalent to GDA94(2010) i.e. no distortions. They are different to those found in SCIMS Online, which are GDA94(1997) coordinates i.e. with distortions. The heights are different to those found in SCIMS Online, which are local AHD71 heights. SCIMS Online values for CORS are determined by local tie surveys which connect to the local survey control network.

Note: The above graph indicates the long-term stability of a CORS and does not represent actual daily movement. The results are calculated daily and trends are monitored. The diagrams shown are updated regularly. Daily differences in CORS position at the millimetre-level are within the limits (noise level) of current GNSS processing techniques.
