DK7553.The coordinates were established by GPS observations
DK7553.and adjusted by the National Geodetic Survey in June 2019.
DK7553
DK7553.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK7553.been affixed to the stable North American Tectonic Plate.
DK7553
DK7553.The coordinates are valid at the epoch date displayed above
DK7553.which is a decimal equivalence of Year/Month/Day.
DK7553
DK7553.Due to the release of the International GNSS Service (IGS) 2014
DK7553.realization of the International Terrestrial Reference Frame of 2014
DK7553.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK7553.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK7553.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK7553.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK7553.currently published epoch of 2010.00.
DK7553
DK7553.Additional information on MYCS2 is available at
DK7553.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK7553
DK7553.The orthometric height was determined by GPS observations and a
DK7553.high-resolution geoid model using precise GPS observation and
DK7553.processing techniques.
DK7553
DK7553.Significant digits in the geoid height do not necessarily reflect accuracy.
DK7553.GEOID18 height accuracy estimate available here.
DK7553
DK7553.The PID for the CORS L1 Phase Center is DR7743.

DK7553
DK7553.The XYZ, and position/ellipsoidal ht. are equivalent.
DK7553
DK7553.The ellipsoidal height was determined by GPS observations
DK7553.and is referenced to NAD 83.
