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.


GNSS Monitoring

Image will open in new window

Note: The above graph indicates the long term stability of a CORSnet-NSW station and does not represent actual daily movement. The results are calculated daily and trends are monitored by CORSnet-NSW staff. The diagrams shown are currently updated monthly. Daily differences in CORS position at the millimetre-level are within the limits (noise level) of current DFSI Spatial Services processing techniques.


Reference Mark Monitoring

Monitoring survey not available for this CORS.

Note: The above tables quantify the movement of the CORS pillar with respect to local reference marks. Surveys are carried out at installation and then after 6 months, 18 months and every two years thereafter. The techniques used, as specified by Geoscience Australia, achieve sub-millimetre precision and can detect minute movements in position or height.
