AJ8807.Formal positional accuracy estimates are not available for this CORS
AJ8807.because its coordinates were determined in part using modeled
AJ8807.velocities. Approximate one-sigma accuracies for latitude, longitude,
AJ8807.and ellipsoid height can be obtained from the short-term time series.
AJ8807.Additional information regarding modeled velocities is available on
AJ8807.the CORS Coordinates for MYCS2 web page:
AJ8807.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AJ8807
AJ8807.The coordinates were established by GPS observations
AJ8807.and adjusted by the National Geodetic Survey in June 2019.
AJ8807
AJ8807.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ8807.been affixed to the stable North American Tectonic Plate.
AJ8807
AJ8807.The coordinates are valid at the epoch date displayed above
AJ8807.which is a decimal equivalence of Year/Month/Day.
AJ8807
AJ8807.Due to the release of the International GNSS Service (IGS) 2014
AJ8807.realization of the International Terrestrial Reference Frame of 2014
AJ8807.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ8807.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ8807.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ8807.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ8807.currently published epoch of 2010.00.

AJ8807.** This station is in an area of known vertical motion. If an
AJ8807.** orthometric height was ever established but is not available
AJ8807.** in the current survey control section, the orthometric height
AJ8807.** is considered suspect. Suspect heights are available in the
AJ8807.** superseded section only if requested.
AJ8807
AJ8807.Significant digits in the geoid height do not necessarily reflect accuracy.

AJ8807.The PID for the CORS L1 Phase Center is DH9346.

AJ8807
AJ8807.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ8807
AJ8807.The ellipsoidal height was determined by GPS observations
AJ8807.and is referenced to NAD 83.
