AF9548.The coordinates were established by GPS observations
AF9548.and adjusted by the National Geodetic Survey in June 2019.
AF9548
AF9548.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9548.been affixed to the stable North American Tectonic Plate.
AF9548
AF9548.The coordinates are valid at the epoch date displayed above
AF9548.which is a decimal equivalence of Year/Month/Day.
AF9548
AF9548.Due to the release of the International GNSS Service (IGS) 2014
AF9548.realization of the International Terrestrial Reference Frame of 2014
AF9548.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9548.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9548.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9548.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9548.currently published epoch of 2010.00.
AF9548
AF9548.Additional information on MYCS2 is available at
AF9548.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9548
AF9548.The orthometric height was determined by GPS observations and a
AF9548.high-resolution geoid model using precise GPS observation and
AF9548.processing techniques.
AF9548
AF9548.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9548.GEOID12B height accuracy estimate available here.
AF9548
AF9548.The PID for the CORS L1 Phase Center is AJ7887.

AF9548.Click photographs - Photos may exist for this station.
AF9548
AF9548.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9548
AF9548.The ellipsoidal height was determined by GPS observations
AF9548.and is referenced to NAD 83.
