DG9300.Formal positional accuracy estimates are not available for this CORS
DG9300.because its coordinates were determined in part using modeled
DG9300.velocities. Approximate one-sigma accuracies for latitude, longitude,
DG9300.and ellipsoid height can be obtained from the short-term time series.
DG9300.Additional information regarding modeled velocities is available on
DG9300.the CORS Coordinates for MYCS2 web page:
DG9300.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DG9300
DG9300.The coordinates were established by GPS observations
DG9300.and adjusted by the National Geodetic Survey in June 2019.
DG9300
DG9300.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9300.been affixed to the stable North American Tectonic Plate.
DG9300
DG9300.The coordinates are valid at the epoch date displayed above
DG9300.which is a decimal equivalence of Year/Month/Day.
DG9300
DG9300.Due to the release of the International GNSS Service (IGS) 2014
DG9300.realization of the International Terrestrial Reference Frame of 2014
DG9300.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9300.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9300.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9300.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9300.currently published epoch of 2010.00.

DG9300.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9300
DG9300.The ellipsoidal height was determined by GPS observations
DG9300.and is referenced to NAD 83.
