DR5991.Formal positional accuracy estimates are not available for this CORS
DR5991.because its coordinates were determined in part using modeled
DR5991.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR5991.and ellipsoid height can be obtained from the short-term time series.
DR5991.Additional information regarding modeled velocities is available on
DR5991.the CORS Coordinates for MYCS2 web page:
DR5991.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR5991
DR5991.The coordinates were established by GPS observations
DR5991.and adjusted by the National Geodetic Survey in September 2020.
DR5991
DR5991.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR5991.been affixed to the stable North American Tectonic Plate.
DR5991
DR5991.The coordinates are valid at the epoch date displayed above
DR5991.which is a decimal equivalence of Year/Month/Day.
DR5991
DR5991.Due to the release of the International GNSS Service (IGS) 2014
DR5991.realization of the International Terrestrial Reference Frame of 2014
DR5991.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR5991.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR5991.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR5991.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR5991.currently published epoch of 2010.00.

DR5991.The XYZ, and position/ellipsoidal ht. are equivalent.
DR5991
DR5991.The ellipsoidal height was determined by GPS observations
DR5991.and is referenced to NAD 83.
