AJ7827.Formal positional accuracy estimates are not available for this CORS
AJ7827.because its coordinates were determined in part using modeled
AJ7827.velocities. Approximate one-sigma accuracies for latitude, longitude,
AJ7827.and ellipsoid height can be obtained from the short-term time series.
AJ7827.Additional information regarding modeled velocities is available on
AJ7827.the CORS Coordinates for MYCS2 web page:
AJ7827.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AJ7827
AJ7827.The coordinates were established by GPS observations
AJ7827.and adjusted by the National Geodetic Survey in June 2019.
AJ7827
AJ7827.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ7827.been affixed to the stable North American Tectonic Plate.
AJ7827
AJ7827.The coordinates are valid at the epoch date displayed above
AJ7827.which is a decimal equivalence of Year/Month/Day.
AJ7827
AJ7827.Due to the release of the International GNSS Service (IGS) 2014
AJ7827.realization of the International Terrestrial Reference Frame of 2014
AJ7827.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ7827.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ7827.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ7827.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ7827.currently published epoch of 2010.00.

AJ7827.** This station is in an area of known vertical motion. If an
AJ7827.** orthometric height was ever established but is not available
AJ7827.** in the current survey control section, the orthometric height
AJ7827.** is considered suspect. Suspect heights are available in the
AJ7827.** superseded section only if requested.
AJ7827
AJ7827.Significant digits in the geoid height do not necessarily reflect accuracy.

AJ7827.The PID for the CORS L1 Phase Center is AJ7828.

AJ7827.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ7827
AJ7827.The ellipsoidal height was determined by GPS observations
AJ7827.and is referenced to NAD 83.
