AJ4434.The coordinates were established by GPS observations
AJ4434.and adjusted by the National Geodetic Survey in June 2019.
AJ4434
AJ4434.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ4434.been affixed to the stable North American Tectonic Plate.
AJ4434
AJ4434.The coordinates are valid at the epoch date displayed above
AJ4434.which is a decimal equivalence of Year/Month/Day.
AJ4434
AJ4434.Due to the release of the International GNSS Service (IGS) 2014
AJ4434.realization of the International Terrestrial Reference Frame of 2014
AJ4434.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ4434.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ4434.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ4434.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ4434.currently published epoch of 2010.00.
AJ4434
AJ4434.Additional information on MYCS2 is available at
AJ4434.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ4434
AJ4434.The orthometric height was determined by GPS observations and a
AJ4434.high-resolution geoid model using precise GPS observation and
AJ4434.processing techniques.
AJ4434
AJ4434.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ4434.GEOID18 height accuracy estimate available here.
AJ4434
AJ4434.The PID for the CORS L1 Phase Center is DI3729.

AJ4434.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ4434
AJ4434.The ellipsoidal height was determined by GPS observations
AJ4434.and is referenced to NAD 83.
