AH3757.The coordinates were established by GPS observations
AH3757.and adjusted by the National Geodetic Survey in August 2011.
AH3757
AH3757.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH3757.been affixed to the stable North American Tectonic Plate.
AH3757
AH3757.The coordinates are valid at the epoch date displayed above
AH3757.which is a decimal equivalence of Year/Month/Day.
AH3757
AH3757.Due to the release of the International GNSS Service (IGS) 2014
AH3757.realization of the International Terrestrial Reference Frame of 2014
AH3757.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH3757.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH3757.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH3757.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH3757.currently published epoch of 2010.00.
AH3757
AH3757.Additional information on MYCS2 is available at
AH3757.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AH3757.Significant digits in the geoid height do not necessarily reflect accuracy.
AH3757.GEOID12B height accuracy estimate available here.

AH3757.The PID for the CORS L1 Phase Center is AJ7945.

AH3757.The XYZ, and position/ellipsoidal ht. are equivalent.
AH3757
AH3757.The ellipsoidal height was determined by GPS observations
AH3757.and is referenced to NAD 83.
