DK4045.The coordinates were established by GPS observations
DK4045.and adjusted by the National Geodetic Survey in June 2019.
DK4045
DK4045.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK4045.been affixed to the stable North American Tectonic Plate.
DK4045
DK4045.The coordinates are valid at the epoch date displayed above
DK4045.which is a decimal equivalence of Year/Month/Day.
DK4045
DK4045.Due to the release of the International GNSS Service (IGS) 2014
DK4045.realization of the International Terrestrial Reference Frame of 2014
DK4045.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK4045.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK4045.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK4045.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK4045.currently published epoch of 2010.00.
DK4045
DK4045.Additional information on MYCS2 is available at
DK4045.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK4045
DK4045.The orthometric height was determined by GPS observations and a
DK4045.high-resolution geoid model using precise GPS observation and
DK4045.processing techniques.
DK4045
DK4045.Significant digits in the geoid height do not necessarily reflect accuracy.
DK4045.GEOID18 height accuracy estimate available here.
DK4045
DK4045.The PID for the CORS L1 Phase Center is DS2788.

DK4045.Click photographs - Photos may exist for this station.
DK4045
DK4045.The XYZ, and position/ellipsoidal ht. are equivalent.
DK4045
DK4045.The ellipsoidal height was determined by GPS observations
DK4045.and is referenced to NAD 83.
