DL7620.The coordinates were established by GPS observations
DL7620.and adjusted by the National Geodetic Survey in June 2022.
DL7620
DL7620.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7620.been affixed to the stable North American Tectonic Plate.
DL7620
DL7620.The coordinates are valid at the epoch date displayed above
DL7620.which is a decimal equivalence of Year/Month/Day.
DL7620
DL7620.Due to the release of the International GNSS Service (IGS) 2014
DL7620.realization of the International Terrestrial Reference Frame of 2014
DL7620.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7620.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7620.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7620.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7620.currently published epoch of 2010.00.
DL7620
DL7620.Additional information on MYCS2 is available at
DL7620.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL7620.Significant digits in the geoid height do not necessarily reflect accuracy.
DL7620.GEOID18 height accuracy estimate available here.

DL7620.The PID for the CORS L1 Phase Center is DR7763.

DL7620
DL7620.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7620
DL7620.The ellipsoidal height was determined by GPS observations
DL7620.and is referenced to NAD 83.
