AF9569.The coordinates were established by GPS observations
AF9569.and adjusted by the National Geodetic Survey in June 2019.
AF9569
AF9569.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9569.been affixed to the stable North American Tectonic Plate.
AF9569
AF9569.The coordinates are valid at the epoch date displayed above
AF9569.which is a decimal equivalence of Year/Month/Day.
AF9569
AF9569.Due to the release of the International GNSS Service (IGS) 2014
AF9569.realization of the International Terrestrial Reference Frame of 2014
AF9569.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9569.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9569.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9569.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9569.currently published epoch of 2010.00.
AF9569
AF9569.Additional information on MYCS2 is available at
AF9569.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9569
AF9569.The orthometric height was determined by GPS observations and a
AF9569.high-resolution geoid model using precise GPS observation and
AF9569.processing techniques.
AF9569
AF9569.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9569.GEOID18 height accuracy estimate available here.
AF9569
AF9569.The PID for the CORS L1 Phase Center is AJ7901.

AF9569.Click photographs - Photos may exist for this station.
AF9569
AF9569.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9569
AF9569.The ellipsoidal height was determined by GPS observations
AF9569.and is referenced to NAD 83.
