AH8301.The coordinates were established by GPS observations
AH8301.and adjusted by the National Geodetic Survey in June 2019.
AH8301
AH8301.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH8301.been affixed to the stable North American Tectonic Plate.
AH8301
AH8301.The coordinates are valid at the epoch date displayed above
AH8301.which is a decimal equivalence of Year/Month/Day.
AH8301
AH8301.Due to the release of the International GNSS Service (IGS) 2014
AH8301.realization of the International Terrestrial Reference Frame of 2014
AH8301.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH8301.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH8301.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH8301.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH8301.currently published epoch of 2010.00.
AH8301
AH8301.Additional information on MYCS2 is available at
AH8301.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AH8301.Significant digits in the geoid height do not necessarily reflect accuracy.
AH8301.GEOID12B height accuracy estimate available here.

AH8301.The PID for the CORS L1 Phase Center is AJ7956.

AH8301.Click photographs - Photos may exist for this station.
AH8301
AH8301.The XYZ, and position/ellipsoidal ht. are equivalent.
AH8301
AH8301.The ellipsoidal height was determined by GPS observations
AH8301.and is referenced to NAD 83.
