DK7758.The coordinates were established by GPS observations
DK7758.and adjusted by the National Geodetic Survey in April 2022.
DK7758
DK7758.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK7758.been affixed to the stable North American Tectonic Plate.
DK7758
DK7758.The coordinates are valid at the epoch date displayed above
DK7758.which is a decimal equivalence of Year/Month/Day.
DK7758
DK7758.Due to the release of the International GNSS Service (IGS) 2014
DK7758.realization of the International Terrestrial Reference Frame of 2014
DK7758.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK7758.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK7758.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK7758.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK7758.currently published epoch of 2010.00.
DK7758
DK7758.Additional information on MYCS2 is available at
DK7758.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK7758
DK7758.The orthometric height was determined by GPS observations and a
DK7758.high-resolution geoid model using precise GPS observation and
DK7758.processing techniques.
DK7758
DK7758.Significant digits in the geoid height do not necessarily reflect accuracy.
DK7758.GEOID18 height accuracy estimate available here.
DK7758
DK7758.The PID for the CORS L1 Phase Center is DR7748.

DK7758.Click photographs - Photos may exist for this station.
DK7758
DK7758.The XYZ, and position/ellipsoidal ht. are equivalent.
DK7758
DK7758.The ellipsoidal height was determined by GPS observations
DK7758.and is referenced to NAD 83.
