AF9554.The coordinates were established by GPS observations
AF9554.and adjusted by the National Geodetic Survey in June 2019.
AF9554
AF9554.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9554.been affixed to the stable North American Tectonic Plate.
AF9554
AF9554.The coordinates are valid at the epoch date displayed above
AF9554.which is a decimal equivalence of Year/Month/Day.
AF9554
AF9554.Due to the release of the International GNSS Service (IGS) 2014
AF9554.realization of the International Terrestrial Reference Frame of 2014
AF9554.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9554.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9554.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9554.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9554.currently published epoch of 2010.00.
AF9554
AF9554.Additional information on MYCS2 is available at
AF9554.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9554
AF9554.The orthometric height was determined by GPS observations and a
AF9554.high-resolution geoid model using precise GPS observation and
AF9554.processing techniques.
AF9554
AF9554.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9554.GEOID18 height accuracy estimate available here.
AF9554
AF9554.The PID for the CORS L1 Phase Center is AJ7893.

AF9554.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9554
AF9554.The ellipsoidal height was determined by GPS observations
AF9554.and is referenced to NAD 83.
