AF9501.The coordinates were established by GPS observations
AF9501.and adjusted by the National Geodetic Survey in June 2019.
AF9501
AF9501.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9501.been affixed to the stable North American Tectonic Plate.
AF9501
AF9501.The coordinates are valid at the epoch date displayed above
AF9501.which is a decimal equivalence of Year/Month/Day.
AF9501
AF9501.Due to the release of the International GNSS Service (IGS) 2014
AF9501.realization of the International Terrestrial Reference Frame of 2014
AF9501.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9501.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9501.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9501.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9501.currently published epoch of 2010.00.
AF9501
AF9501.Additional information on MYCS2 is available at
AF9501.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9501
AF9501.The orthometric height was determined by GPS observations and a
AF9501.high-resolution geoid model using precise GPS observation and
AF9501.processing techniques.
AF9501
AF9501.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9501.GEOID18 height accuracy estimate available here.
AF9501
AF9501.The PID for the CORS L1 Phase Center is AJ7871.

AF9501.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9501
AF9501.The ellipsoidal height was determined by GPS observations
AF9501.and is referenced to NAD 83.
