AF9503.The coordinates were established by GPS observations
AF9503.and adjusted by the National Geodetic Survey in June 2019.
AF9503
AF9503.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9503.been affixed to the stable North American Tectonic Plate.
AF9503
AF9503.The coordinates are valid at the epoch date displayed above
AF9503.which is a decimal equivalence of Year/Month/Day.
AF9503
AF9503.Due to the release of the International GNSS Service (IGS) 2014
AF9503.realization of the International Terrestrial Reference Frame of 2014
AF9503.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9503.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9503.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9503.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9503.currently published epoch of 2010.00.
AF9503
AF9503.Additional information on MYCS2 is available at
AF9503.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9503
AF9503.The orthometric height was determined by GPS observations and a
AF9503.high-resolution geoid model using precise GPS observation and
AF9503.processing techniques.
AF9503
AF9503.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9503.GEOID18 height accuracy estimate available here.
AF9503
AF9503.The PID for the CORS L1 Phase Center is AJ7873.

AF9503.Click photographs - Photos may exist for this station.
AF9503
AF9503.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9503
AF9503.The ellipsoidal height was determined by GPS observations
AF9503.and is referenced to NAD 83.
