AF9657
AF9657.Formal positional accuracy estimates are not available for this CORS
AF9657.because its coordinates were determined in part using modeled
AF9657.velocities. Approximate one-sigma accuracies for latitude, longitude,
AF9657.and ellipsoid height can be obtained from the short-term time series.
AF9657.Additional information regarding modeled velocities is available on
AF9657.the CORS Coordinates for MYCS2 web page:
AF9657.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AF9657
AF9657.The coordinates were established by GPS observations
AF9657.and adjusted by the National Geodetic Survey in June 2019.
AF9657
AF9657.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9657.been affixed to the stable North American Tectonic Plate.
AF9657
AF9657.The coordinates are valid at the epoch date displayed above
AF9657.which is a decimal equivalence of Year/Month/Day.
AF9657
AF9657.Due to the release of the International GNSS Service (IGS) 2014
AF9657.realization of the International Terrestrial Reference Frame of 2014
AF9657.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9657.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9657.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9657.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9657.currently published epoch of 2010.00.

AF9657.Additional information on MYCS2 is available at
AF9657.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9657
AF9657.The orthometric height was determined by GPS observations and a
AF9657.high-resolution geoid model using precise GPS observation and
AF9657.processing techniques.
AF9657
AF9657.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9657.GEOID18 height accuracy estimate available here.
AF9657
AF9657.The PID for the CORS L1 Phase Center is AI7429.

AF9657.Click photographs - Photos may exist for this station.
AF9657
AF9657.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9657
AF9657.The ellipsoidal height was determined by GPS observations
AF9657.and is referenced to NAD 83.
