AJ6820.The coordinates were established by GPS observations
AJ6820.and adjusted by the National Geodetic Survey in June 2019.
AJ6820
AJ6820.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ6820.been affixed to the stable North American Tectonic Plate.
AJ6820
AJ6820.The coordinates are valid at the epoch date displayed above
AJ6820.which is a decimal equivalence of Year/Month/Day.
AJ6820
AJ6820.Due to the release of the International GNSS Service (IGS) 2014
AJ6820.realization of the International Terrestrial Reference Frame of 2014
AJ6820.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ6820.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ6820.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ6820.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ6820.currently published epoch of 2010.00.
AJ6820
AJ6820.Additional information on MYCS2 is available at
AJ6820.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ6820
AJ6820.The orthometric height was determined by GPS observations and a
AJ6820.high-resolution geoid model using precise GPS observation and
AJ6820.processing techniques.
AJ6820
AJ6820.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ6820.GEOID18 height accuracy estimate available here.
AJ6820
AJ6820.The PID for the CORS L1 Phase Center is DO1607.

AJ6820
AJ6820.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ6820
AJ6820.The ellipsoidal height was determined by GPS observations
AJ6820.and is referenced to NAD 83.
