DK6521.The coordinates were established by GPS observations
DK6521.and adjusted by the National Geodetic Survey in June 2019.
DK6521
DK6521.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK6521.been affixed to the stable North American Tectonic Plate.
DK6521
DK6521.The coordinates are valid at the epoch date displayed above
DK6521.which is a decimal equivalence of Year/Month/Day.
DK6521
DK6521.Due to the release of the International GNSS Service (IGS) 2014
DK6521.realization of the International Terrestrial Reference Frame of 2014
DK6521.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK6521.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK6521.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK6521.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK6521.currently published epoch of 2010.00.
DK6521
DK6521.Additional information on MYCS2 is available at
DK6521.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK6521
DK6521.The orthometric height was determined by GPS observations and a
DK6521.high-resolution geoid model using precise GPS observation and
DK6521.processing techniques.
DK6521
DK6521.Significant digits in the geoid height do not necessarily reflect accuracy.
DK6521.GEOID18 height accuracy estimate available here.

DK6521.The PID for the CORS L1 Phase Center is DL1704.

DK6521.Click photographs - Photos may exist for this station.
DK6521
DK6521.The XYZ, and position/ellipsoidal ht. are equivalent.
DK6521
DK6521.The ellipsoidal height was determined by GPS observations
DK6521.and is referenced to NAD 83.
