AJ8468.The coordinates were established by GPS observations
AJ8468.and adjusted by the National Geodetic Survey in May 2020.
AJ8468
AJ8468.NAD 83(PA11) refers to NAD 83 coordinates where the reference frame has
AJ8468.been affixed to the stable Pacific Tectonic Plate.
AJ8468
AJ8468.The coordinates are valid at the epoch date displayed above
AJ8468.which is a decimal equivalence of Year/Month/Day.
AJ8468
AJ8468.Due to the release of the International GNSS Service (IGS) 2014
AJ8468.realization of the International Terrestrial Reference Frame of 2014
AJ8468.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ8468.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ8468.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ8468.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ8468.currently published epoch of 2010.00.
AJ8468
AJ8468.Additional information on MYCS2 is available at
AJ8468.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ8468
AJ8468.The orthometric height was determined by GPS observations and a
AJ8468.high-resolution geoid model using precise GPS observation and
AJ8468.processing techniques.
AJ8468
AJ8468.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ8468.GEOID12B height accuracy estimate available here.
AJ8468
AJ8468.The PID for the CORS L1 Phase Center is AJ8469.

AJ8468
AJ8468.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ8468
AJ8468.The ellipsoidal height was determined by GPS observations
AJ8468.and is referenced to NAD 83.
