AJ1818.The coordinates were established by GPS observations
AJ1818.and adjusted by the National Geodetic Survey in June 2019.
AJ1818
AJ1818.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ1818.been affixed to the stable North American Tectonic Plate.
AJ1818
AJ1818.The coordinates are valid at the epoch date displayed above
AJ1818.which is a decimal equivalence of Year/Month/Day.
AJ1818
AJ1818.Due to the release of the International GNSS Service (IGS) 2014
AJ1818.realization of the International Terrestrial Reference Frame of 2014
AJ1818.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ1818.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ1818.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ1818.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ1818.currently published epoch of 2010.00.
AJ1818
AJ1818.Additional information on MYCS2 is available at
AJ1818.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ1818
AJ1818.The orthometric height was determined by GPS observations and a
AJ1818.high-resolution geoid model using precise GPS observation and
AJ1818.processing techniques.
AJ1818
AJ1818.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ1818.GEOID18 height accuracy estimate available here.
AJ1818
AJ1818.The PID for the CORS L1 Phase Center is AJ1819.

AJ1818
AJ1818.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ1818
AJ1818.The ellipsoidal height was determined by GPS observations
AJ1818.and is referenced to NAD 83.
