DH6922.Formal positional accuracy estimates are not available for this CORS
DH6922.because its coordinates were determined in part using modeled
DH6922.velocities. Approximate one-sigma accuracies for latitude, longitude,
DH6922.and ellipsoid height can be obtained from the short-term time series.
DH6922.Additional information regarding modeled velocities is available on
DH6922.the CORS Coordinates for MYCS2 web page:
DH6922.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DH6922
DH6922.The coordinates were established by GPS observations
DH6922.and adjusted by the National Geodetic Survey in November 2005.
DH6922
DH6922.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
DH6922
DH6922.The coordinates are valid at the epoch date displayed above
DH6922.which is a decimal equivalence of Year/Month/Day.
DH6922
DH6922.Due to the release of the International GNSS Service (IGS) 2014
DH6922.realization of the International Terrestrial Reference Frame of 2014
DH6922.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH6922.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH6922.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH6922.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH6922.currently published epoch of 2010.00.

DH6922.The XYZ, and position/ellipsoidal ht. are equivalent.
DH6922
DH6922.The ellipsoidal height was determined by GPS observations
DH6922.and is referenced to NAD 83.
