 DK4115.The positional and height information provided upon this datasheet are not
 DK4115.officially recognized by the Government of Canada, provincial governments
 DK4115.within Canada, nor are they intended to replace or substitute for them.
 DK4115.The intent of sharing this data is to allow access to positions or heights
 DK4115.recognized by the United States Government. Passive control that is used by
 DK4115.both nations may share the same or similar designations or descriptions but
 DK4115.do not share official positions or heights. The 'Station Description' may
 DK4115.originate from a Canadian 'Station Report' and if so contains information
 DK4115.licensed under the 'Open Government License - Canada'.
 DK4115
 DK4115.The coordinates were established by GPS observations
 DK4115.and adjusted by the National Geodetic Survey in April 2025.
 DK4115
 DK4115.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DK4115.been affixed to the stable North American Tectonic Plate. 
 DK4115
 DK4115.The coordinates are valid at the epoch date displayed above
 DK4115.which is a decimal equivalence of Year/Month/Day.
 DK4115
 DK4115.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DK4115.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DK4115.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DK4115.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DK4115.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DK4115.published epoch of 2010.00.
 DK4115
 DK4115.Additional information on MYCS is available at:

 DK4115.The PID for the CORS L1 Phase Center is DK4116.

 DK4115.The XYZ, and position/ellipsoidal ht. are equivalent.
 DK4115
 DK4115.The ellipsoidal height was determined by GPS observations
 DK4115.and is referenced to NAD 83.
