AF9558.The coordinates were established by GPS observations
AF9558.and adjusted by the National Geodetic Survey in June 2019.
AF9558
AF9558.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9558.been affixed to the stable North American Tectonic Plate.
AF9558
AF9558.The coordinates are valid at the epoch date displayed above
AF9558.which is a decimal equivalence of Year/Month/Day.
AF9558
AF9558.Due to the release of the International GNSS Service (IGS) 2014
AF9558.realization of the International Terrestrial Reference Frame of 2014
AF9558.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9558.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9558.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9558.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9558.currently published epoch of 2010.00.
AF9558
AF9558.Additional information on MYCS2 is available at
AF9558.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9558
AF9558.The orthometric height was determined by GPS observations and a
AF9558.high-resolution geoid model using precise GPS observation and
AF9558.processing techniques.
AF9558
AF9558.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9558.GEOID18 height accuracy estimate available here.
AF9558
AF9558.The PID for the CORS L1 Phase Center is AJ7894.

AF9558.Click photographs - Photos may exist for this station.
AF9558
AF9558.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9558
AF9558.The ellipsoidal height was determined by GPS observations
AF9558.and is referenced to NAD 83.
