AF9559.The coordinates were established by GPS observations
AF9559.and adjusted by the National Geodetic Survey in June 2019.
AF9559
AF9559.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9559.been affixed to the stable North American Tectonic Plate.
AF9559
AF9559.The coordinates are valid at the epoch date displayed above
AF9559.which is a decimal equivalence of Year/Month/Day.
AF9559
AF9559.Due to the release of the International GNSS Service (IGS) 2014
AF9559.realization of the International Terrestrial Reference Frame of 2014
AF9559.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9559.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9559.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9559.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9559.currently published epoch of 2010.00.
AF9559
AF9559.Additional information on MYCS2 is available at
AF9559.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9559.** This station is in an area of known vertical motion. If an
AF9559.** orthometric height was ever established but is not available
AF9559.** in the current survey control section, the orthometric height
AF9559.** is considered suspect. Suspect heights are available in the
AF9559.** superseded section only if requested.
AF9559
AF9559.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9559.GEOID18 height accuracy estimate available here.

AF9559.The PID for the CORS L1 Phase Center is AJ7895.

AF9559.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9559
AF9559.The ellipsoidal height was determined by GPS observations
AF9559.and is referenced to NAD 83.
