AF9507.Formal positional accuracy estimates are not available for this CORS
AF9507.because its coordinates were determined in part using modeled
AF9507.velocities. Approximate one-sigma accuracies for latitude, longitude,
AF9507.and ellipsoid height can be obtained from the short-term time series.
AF9507.Additional information regarding modeled velocities is available on
AF9507.the CORS Coordinates for MYCS2 web page:
AF9507.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AF9507
AF9507.The coordinates were established by GPS observations
AF9507.and adjusted by the National Geodetic Survey in June 2019.
AF9507
AF9507.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9507.been affixed to the stable North American Tectonic Plate.
AF9507
AF9507.The coordinates are valid at the epoch date displayed above
AF9507.which is a decimal equivalence of Year/Month/Day.
AF9507
AF9507.Due to the release of the International GNSS Service (IGS) 2014
AF9507.realization of the International Terrestrial Reference Frame of 2014
AF9507.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9507.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9507.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9507.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9507.currently published epoch of 2010.00.

AF9507.Additional information on MYCS2 is available at
AF9507.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9507
AF9507.The orthometric height was determined by GPS observations and a
AF9507.high-resolution geoid model using precise GPS observation and
AF9507.processing techniques.
AF9507
AF9507.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9507.GEOID18 height accuracy estimate available here.
AF9507
AF9507.The PID for the CORS L1 Phase Center is AJ7875.

AF9507.Click photographs - Photos may exist for this station.
AF9507
AF9507.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9507
AF9507.The ellipsoidal height was determined by GPS observations
AF9507.and is referenced to NAD 83.
