DF8477.Formal positional accuracy estimates are not available for this CORS
DF8477.because its coordinates were determined in part using modeled
DF8477.velocities. Approximate one-sigma accuracies for latitude, longitude,
DF8477.and ellipsoid height can be obtained from the short-term time series.
DF8477.Additional information regarding modeled velocities is available on
DF8477.the CORS Coordinates for MYCS2 web page:
DF8477.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DF8477
DF8477.The coordinates were established by GPS observations
DF8477.and adjusted by the National Geodetic Survey in October 2003.
DF8477
DF8477.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
DF8477
DF8477.The coordinates are valid at the epoch date displayed above
DF8477.which is a decimal equivalence of Year/Month/Day.
DF8477
DF8477.Due to the release of the International GNSS Service (IGS) 2014
DF8477.realization of the International Terrestrial Reference Frame of 2014
DF8477.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8477.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8477.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8477.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8477.currently published epoch of 2010.00.

DF8477.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8477
DF8477.The ellipsoidal height was determined by GPS observations
DF8477.and is referenced to NAD 83.
