AF9640.The coordinates were established by GPS observations
AF9640.and adjusted by the National Geodetic Survey in June 2019.
AF9640
AF9640.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9640.been affixed to the stable North American Tectonic Plate.
AF9640
AF9640.The coordinates are valid at the epoch date displayed above
AF9640.which is a decimal equivalence of Year/Month/Day.
AF9640
AF9640.Due to the release of the International GNSS Service (IGS) 2014
AF9640.realization of the International Terrestrial Reference Frame of 2014
AF9640.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9640.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9640.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9640.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9640.currently published epoch of 2010.00.
AF9640
AF9640.Additional information on MYCS2 is available at
AF9640.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9640.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9640.GEOID18 height accuracy estimate available here.
AF9640
AF9640.The PID for the CORS L1 Phase Center is AE1836.

AF9640.Click photographs - Photos may exist for this station.
AF9640
AF9640.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9640
AF9640.The ellipsoidal height was determined by GPS observations
AF9640.and is referenced to NAD 83.
