DO5451.The coordinates were established by GPS observations
DO5451.and adjusted by the National Geodetic Survey in May 2020.
DO5451
DO5451.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO5451.been affixed to the stable North American Tectonic Plate.
DO5451
DO5451.The coordinates are valid at the epoch date displayed above
DO5451.which is a decimal equivalence of Year/Month/Day.
DO5451
DO5451.Due to the release of the International GNSS Service (IGS) 2014
DO5451.realization of the International Terrestrial Reference Frame of 2014
DO5451.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO5451.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO5451.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO5451.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO5451.currently published epoch of 2010.00.
DO5451
DO5451.Additional information on MYCS2 is available at
DO5451.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DO5451
DO5451.The orthometric height was determined by GPS observations and a
DO5451.high-resolution geoid model using precise GPS observation and
DO5451.processing techniques.
DO5451
DO5451.Significant digits in the geoid height do not necessarily reflect accuracy.
DO5451.GEOID18 height accuracy estimate available here.
DO5451
DO5451.The PID for the CORS L1 Phase Center is DR1530.

DO5451.Click photographs - Photos may exist for this station.
DO5451
DO5451.The XYZ, and position/ellipsoidal ht. are equivalent.
DO5451
DO5451.The ellipsoidal height was determined by GPS observations
DO5451.and is referenced to NAD 83.
