AF9676.The coordinates were established by GPS observations
AF9676.and adjusted by the National Geodetic Survey in June 2019.
AF9676
AF9676.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9676.been affixed to the stable North American Tectonic Plate.
AF9676
AF9676.The coordinates are valid at the epoch date displayed above
AF9676.which is a decimal equivalence of Year/Month/Day.
AF9676
AF9676.Due to the release of the International GNSS Service (IGS) 2014
AF9676.realization of the International Terrestrial Reference Frame of 2014
AF9676.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9676.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9676.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9676.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9676.currently published epoch of 2010.00.
AF9676
AF9676.Additional information on MYCS2 is available at
AF9676.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9676.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9676.GEOID12B height accuracy estimate available here.

AF9676.The PID for the CORS L1 Phase Center is AF9677.

AF9676.Click photographs - Photos may exist for this station.
AF9676
AF9676.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9676
AF9676.The ellipsoidal height was determined by GPS observations
AF9676.and is referenced to NAD 83.
