AF9550.The coordinates were established by GPS observations
AF9550.and adjusted by the National Geodetic Survey in June 2019.
AF9550
AF9550.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9550.been affixed to the stable North American Tectonic Plate.
AF9550
AF9550.The coordinates are valid at the epoch date displayed above
AF9550.which is a decimal equivalence of Year/Month/Day.
AF9550
AF9550.Due to the release of the International GNSS Service (IGS) 2014
AF9550.realization of the International Terrestrial Reference Frame of 2014
AF9550.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9550.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9550.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9550.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9550.currently published epoch of 2010.00.
AF9550
AF9550.Additional information on MYCS2 is available at
AF9550.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9550
AF9550.The orthometric height was determined by GPS observations and a
AF9550.high-resolution geoid model using precise GPS observation and
AF9550.processing techniques.
AF9550
AF9550.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9550.GEOID18 height accuracy estimate available here.
AF9550
AF9550.The PID for the CORS L1 Phase Center is AJ7889.

AF9550.Click photographs - Photos may exist for this station.
AF9550
AF9550.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9550
AF9550.The ellipsoidal height was determined by GPS observations
AF9550.and is referenced to NAD 83.
