AI1402.The coordinates were established by GPS observations
AI1402.and adjusted by the National Geodetic Survey in June 2019.
AI1402
AI1402.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI1402.been affixed to the stable North American Tectonic Plate.
AI1402
AI1402.The coordinates are valid at the epoch date displayed above
AI1402.which is a decimal equivalence of Year/Month/Day.
AI1402
AI1402.Due to the release of the International GNSS Service (IGS) 2014
AI1402.realization of the International Terrestrial Reference Frame of 2014
AI1402.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI1402.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI1402.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI1402.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI1402.currently published epoch of 2010.00.
AI1402
AI1402.Additional information on MYCS2 is available at
AI1402.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AI1402
AI1402.The orthometric height was determined by GPS observations and a
AI1402.high-resolution geoid model using precise GPS observation and
AI1402.processing techniques.
AI1402
AI1402.Significant digits in the geoid height do not necessarily reflect accuracy.
AI1402.GEOID18 height accuracy estimate available here.
AI1402
AI1402.The PID for the CORS L1 Phase Center is AJ7965.

AI1402.The XYZ, and position/ellipsoidal ht. are equivalent.
AI1402
AI1402.The ellipsoidal height was determined by GPS observations
AI1402.and is referenced to NAD 83.
