AH5461.The coordinates were established by GPS observations
AH5461.and adjusted by the National Geodetic Survey in June 2019.
AH5461
AH5461.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH5461.been affixed to the stable North American Tectonic Plate.
AH5461
AH5461.The coordinates are valid at the epoch date displayed above
AH5461.which is a decimal equivalence of Year/Month/Day.
AH5461
AH5461.Due to the release of the International GNSS Service (IGS) 2014
AH5461.realization of the International Terrestrial Reference Frame of 2014
AH5461.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH5461.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH5461.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH5461.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH5461.currently published epoch of 2010.00.
AH5461
AH5461.Additional information on MYCS2 is available at
AH5461.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AH5461
AH5461.The orthometric height was determined by GPS observations and a
AH5461.high-resolution geoid model using precise GPS observation and
AH5461.processing techniques.
AH5461
AH5461.Significant digits in the geoid height do not necessarily reflect accuracy.
AH5461.GEOID18 height accuracy estimate available here.
AH5461
AH5461.The PID for the CORS L1 Phase Center is AJ7950.

AH5461.Click photographs - Photos may exist for this station.
AH5461
AH5461.The XYZ, and position/ellipsoidal ht. are equivalent.
AH5461
AH5461.The ellipsoidal height was determined by GPS observations
AH5461.and is referenced to NAD 83.
