DK7756.The coordinates were established by GPS observations
DK7756.and adjusted by the National Geodetic Survey in June 2021.
DK7756
DK7756.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK7756.been affixed to the stable North American Tectonic Plate.
DK7756
DK7756.The coordinates are valid at the epoch date displayed above
DK7756.which is a decimal equivalence of Year/Month/Day.
DK7756
DK7756.Due to the release of the International GNSS Service (IGS) 2014
DK7756.realization of the International Terrestrial Reference Frame of 2014
DK7756.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK7756.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK7756.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK7756.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK7756.currently published epoch of 2010.00.
DK7756
DK7756.Additional information on MYCS2 is available at
DK7756.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK7756
DK7756.The orthometric height was determined by GPS observations and a
DK7756.high-resolution geoid model using precise GPS observation and
DK7756.processing techniques.
DK7756
DK7756.Significant digits in the geoid height do not necessarily reflect accuracy.
DK7756.GEOID18 height accuracy estimate available here.
DK7756
DK7756.The PID for the CORS L1 Phase Center is DR7747.

DK7756
DK7756.The XYZ, and position/ellipsoidal ht. are equivalent.
DK7756
DK7756.The ellipsoidal height was determined by GPS observations
DK7756.and is referenced to NAD 83.
