DK6525.The coordinates were established by GPS observations
DK6525.and adjusted by the National Geodetic Survey in May 2020.
DK6525
DK6525.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK6525.been affixed to the stable North American Tectonic Plate.
DK6525
DK6525.The coordinates are valid at the epoch date displayed above
DK6525.which is a decimal equivalence of Year/Month/Day.
DK6525
DK6525.Due to the release of the International GNSS Service (IGS) 2014
DK6525.realization of the International Terrestrial Reference Frame of 2014
DK6525.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK6525.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK6525.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK6525.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK6525.currently published epoch of 2010.00.
DK6525
DK6525.Additional information on MYCS2 is available at
DK6525.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK6525
DK6525.The orthometric height was determined by GPS observations and a
DK6525.high-resolution geoid model using precise GPS observation and
DK6525.processing techniques.
DK6525
DK6525.Significant digits in the geoid height do not necessarily reflect accuracy.
DK6525.GEOID18 height accuracy estimate available here.
DK6525
DK6525.The PID for the CORS L1 Phase Center is DR1509.

DK6525.Click photographs - Photos may exist for this station.
DK6525
DK6525.The XYZ, and position/ellipsoidal ht. are equivalent.
DK6525
DK6525.The ellipsoidal height was determined by GPS observations
DK6525.and is referenced to NAD 83.
