AF9502.The coordinates were established by GPS observations
AF9502.and adjusted by the National Geodetic Survey in June 2019.
AF9502
AF9502.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9502.been affixed to the stable North American Tectonic Plate.
AF9502
AF9502.The coordinates are valid at the epoch date displayed above
AF9502.which is a decimal equivalence of Year/Month/Day.
AF9502
AF9502.Due to the release of the International GNSS Service (IGS) 2014
AF9502.realization of the International Terrestrial Reference Frame of 2014
AF9502.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9502.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9502.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9502.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9502.currently published epoch of 2010.00.
AF9502
AF9502.Additional information on MYCS2 is available at
AF9502.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9502
AF9502.The orthometric height was determined by GPS observations and a
AF9502.high-resolution geoid model using precise GPS observation and
AF9502.processing techniques.
AF9502
AF9502.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9502.GEOID18 height accuracy estimate available here.
AF9502
AF9502.The PID for the CORS L1 Phase Center is AJ7872.

AF9502.Click photographs - Photos may exist for this station.
AF9502
AF9502.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9502
AF9502.The ellipsoidal height was determined by GPS observations
AF9502.and is referenced to NAD 83.
