AJ5555.The coordinates were established by GPS observations
AJ5555.and adjusted by the National Geodetic Survey in July 2020.
AJ5555
AJ5555.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ5555.been affixed to the stable North American Tectonic Plate.
AJ5555
AJ5555.The coordinates are valid at the epoch date displayed above
AJ5555.which is a decimal equivalence of Year/Month/Day.
AJ5555
AJ5555.Due to the release of the International GNSS Service (IGS) 2014
AJ5555.realization of the International Terrestrial Reference Frame of 2014
AJ5555.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ5555.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ5555.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ5555.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ5555.currently published epoch of 2010.00.
AJ5555
AJ5555.Additional information on MYCS2 is available at
AJ5555.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ5555
AJ5555.The orthometric height was determined by differential leveling and
AJ5555.adjusted by the NATIONAL GEODETIC SURVEY
AJ5555.in October 2009.
AJ5555
AJ5555.No vertical observational check was made to the station.
AJ5555
AJ5555.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ5555.GEOID18 height accuracy estimate available here.
AJ5555
AJ5555.The PID for the CORS L1 Phase Center is DR5926.

AJ5555.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ5555
AJ5555.The ellipsoidal height was determined by GPS observations
AJ5555.and is referenced to NAD 83.
