AJ1822.The coordinates were established by GPS observations
AJ1822.and adjusted by the National Geodetic Survey in June 2019.
AJ1822
AJ1822.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ1822.been affixed to the stable North American Tectonic Plate.
AJ1822
AJ1822.The coordinates are valid at the epoch date displayed above
AJ1822.which is a decimal equivalence of Year/Month/Day.
AJ1822
AJ1822.Due to the release of the International GNSS Service (IGS) 2014
AJ1822.realization of the International Terrestrial Reference Frame of 2014
AJ1822.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ1822.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ1822.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ1822.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ1822.currently published epoch of 2010.00.
AJ1822
AJ1822.Additional information on MYCS2 is available at
AJ1822.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ1822
AJ1822.The orthometric height was determined by GPS observations and a
AJ1822.high-resolution geoid model using precise GPS observation and
AJ1822.processing techniques.
AJ1822
AJ1822.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ1822.GEOID18 height accuracy estimate available here.
AJ1822
AJ1822.The PID for the CORS L1 Phase Center is AJ1823.

AJ1822.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ1822
AJ1822.The ellipsoidal height was determined by GPS observations
AJ1822.and is referenced to NAD 83.
