AH6078.The coordinates were established by GPS observations
AH6078.and adjusted by the National Geodetic Survey in June 2019.
AH6078
AH6078.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH6078.been affixed to the stable North American Tectonic Plate.
AH6078
AH6078.The coordinates are valid at the epoch date displayed above
AH6078.which is a decimal equivalence of Year/Month/Day.
AH6078
AH6078.Due to the release of the International GNSS Service (IGS) 2014
AH6078.realization of the International Terrestrial Reference Frame of 2014
AH6078.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH6078.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH6078.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH6078.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH6078.currently published epoch of 2010.00.
AH6078
AH6078.Additional information on MYCS2 is available at
AH6078.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AH6078
AH6078.The orthometric height was determined by GPS observations and a
AH6078.high-resolution geoid model using precise GPS observation and
AH6078.processing techniques.
AH6078
AH6078.Significant digits in the geoid height do not necessarily reflect accuracy.
AH6078.GEOID18 height accuracy estimate available here.
AH6078
AH6078.The PID for the CORS L1 Phase Center is AJ7951.

AH6078.Click photographs - Photos may exist for this station.
AH6078
AH6078.The XYZ, and position/ellipsoidal ht. are equivalent.
AH6078
AH6078.The ellipsoidal height was determined by GPS observations
AH6078.and is referenced to NAD 83.
