AH9090.The coordinates were established by GPS observations
AH9090.and adjusted by the National Geodetic Survey in June 2019.
AH9090
AH9090.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH9090.been affixed to the stable North American Tectonic Plate.
AH9090
AH9090.The coordinates are valid at the epoch date displayed above
AH9090.which is a decimal equivalence of Year/Month/Day.
AH9090
AH9090.Due to the release of the International GNSS Service (IGS) 2014
AH9090.realization of the International Terrestrial Reference Frame of 2014
AH9090.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH9090.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH9090.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH9090.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH9090.currently published epoch of 2010.00.
AH9090
AH9090.Additional information on MYCS2 is available at
AH9090.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AH9090
AH9090.The orthometric height was determined by GPS observations and a
AH9090.high-resolution geoid model using precise GPS observation and
AH9090.processing techniques.
AH9090
AH9090.Significant digits in the geoid height do not necessarily reflect accuracy.
AH9090.GEOID18 height accuracy estimate available here.
AH9090
AH9090.The PID for the CORS L1 Phase Center is AJ7961.

AH9090.Click photographs - Photos may exist for this station.
AH9090
AH9090.The XYZ, and position/ellipsoidal ht. are equivalent.
AH9090
AH9090.The ellipsoidal height was determined by GPS observations
AH9090.and is referenced to NAD 83.
