DR3771.Formal positional accuracy estimates are not available for this CORS
DR3771.because its coordinates were determined in part using modeled
DR3771.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR3771.and ellipsoid height can be obtained from the short-term time series.
DR3771.Additional information regarding modeled velocities is available on
DR3771.the CORS Coordinates for MYCS2 web page:
DR3771.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR3771
DR3771.The coordinates were established by GPS observations
DR3771.and adjusted by the National Geodetic Survey in January 2020.
DR3771
DR3771.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR3771.been affixed to the stable North American Tectonic Plate.
DR3771
DR3771.The coordinates are valid at the epoch date displayed above
DR3771.which is a decimal equivalence of Year/Month/Day.
DR3771
DR3771.Due to the release of the International GNSS Service (IGS) 2014
DR3771.realization of the International Terrestrial Reference Frame of 2014
DR3771.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR3771.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR3771.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR3771.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR3771.currently published epoch of 2010.00.

DR3771.The XYZ, and position/ellipsoidal ht. are equivalent.
DR3771
DR3771.The ellipsoidal height was determined by GPS observations
DR3771.and is referenced to NAD 83.
