AF9496.The coordinates were established by GPS observations
AF9496.and adjusted by the National Geodetic Survey in June 2019.
AF9496
AF9496.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9496.been affixed to the stable North American Tectonic Plate.
AF9496
AF9496.The coordinates are valid at the epoch date displayed above
AF9496.which is a decimal equivalence of Year/Month/Day.
AF9496
AF9496.Due to the release of the International GNSS Service (IGS) 2014
AF9496.realization of the International Terrestrial Reference Frame of 2014
AF9496.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9496.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9496.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9496.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9496.currently published epoch of 2010.00.
AF9496
AF9496.Additional information on MYCS2 is available at
AF9496.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9496
AF9496.The orthometric height was determined by GPS observations and a
AF9496.high-resolution geoid model using precise GPS observation and
AF9496.processing techniques.
AF9496
AF9496.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9496.GEOID18 height accuracy estimate available here.
AF9496
AF9496.The PID for the CORS L1 Phase Center is AJ7867.

AF9496
AF9496.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9496
AF9496.The ellipsoidal height was determined by GPS observations
AF9496.and is referenced to NAD 83.
