AI1404.The coordinates were established by GPS observations
AI1404.and adjusted by the National Geodetic Survey in June 2019.
AI1404
AI1404.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI1404.been affixed to the stable North American Tectonic Plate.
AI1404
AI1404.The coordinates are valid at the epoch date displayed above
AI1404.which is a decimal equivalence of Year/Month/Day.
AI1404
AI1404.Due to the release of the International GNSS Service (IGS) 2014
AI1404.realization of the International Terrestrial Reference Frame of 2014
AI1404.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI1404.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI1404.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI1404.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI1404.currently published epoch of 2010.00.
AI1404
AI1404.Additional information on MYCS2 is available at
AI1404.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AI1404
AI1404.The orthometric height was determined by GPS observations and a
AI1404.high-resolution geoid model using precise GPS observation and
AI1404.processing techniques.
AI1404
AI1404.Significant digits in the geoid height do not necessarily reflect accuracy.
AI1404.GEOID18 height accuracy estimate available here.

AI1404.The PID for the CORS L1 Phase Center is AJ7966.

AI1404.The XYZ, and position/ellipsoidal ht. are equivalent.
AI1404
AI1404.The ellipsoidal height was determined by GPS observations
AI1404.and is referenced to NAD 83.
