AI3680.The coordinates were established by GPS observations
AI3680.and adjusted by the National Geodetic Survey in June 2019.
AI3680
AI3680.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI3680.been affixed to the stable North American Tectonic Plate.
AI3680
AI3680.The coordinates are valid at the epoch date displayed above
AI3680.which is a decimal equivalence of Year/Month/Day.
AI3680
AI3680.Due to the release of the International GNSS Service (IGS) 2014
AI3680.realization of the International Terrestrial Reference Frame of 2014
AI3680.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI3680.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI3680.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI3680.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI3680.currently published epoch of 2010.00.
AI3680
AI3680.Additional information on MYCS2 is available at
AI3680.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AI3680
AI3680.The orthometric height was determined by GPS observations and a
AI3680.high-resolution geoid model using precise GPS observation and
AI3680.processing techniques.
AI3680
AI3680.Significant digits in the geoid height do not necessarily reflect accuracy.
AI3680.GEOID18 height accuracy estimate available here.
AI3680
AI3680.The PID for the CORS L1 Phase Center is DR1457.

AI3680.Click photographs - Photos may exist for this station.
AI3680
AI3680.The XYZ, and position/ellipsoidal ht. are equivalent.
AI3680
AI3680.The ellipsoidal height was determined by GPS observations
AI3680.and is referenced to NAD 83.
