AJ1816.The coordinates were established by GPS observations
AJ1816.and adjusted by the National Geodetic Survey in June 2019.
AJ1816
AJ1816.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ1816.been affixed to the stable North American Tectonic Plate.
AJ1816
AJ1816.The coordinates are valid at the epoch date displayed above
AJ1816.which is a decimal equivalence of Year/Month/Day.
AJ1816
AJ1816.Due to the release of the International GNSS Service (IGS) 2014
AJ1816.realization of the International Terrestrial Reference Frame of 2014
AJ1816.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ1816.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ1816.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ1816.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ1816.currently published epoch of 2010.00.
AJ1816
AJ1816.Additional information on MYCS2 is available at
AJ1816.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ1816
AJ1816.The orthometric height was determined by GPS observations and a
AJ1816.high-resolution geoid model using precise GPS observation and
AJ1816.processing techniques.
AJ1816
AJ1816.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ1816.GEOID18 height accuracy estimate available here.
AJ1816
AJ1816.The PID for the CORS L1 Phase Center is AJ1817.

AJ1816.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ1816
AJ1816.The ellipsoidal height was determined by GPS observations
AJ1816.and is referenced to NAD 83.
