DR8389.Formal positional accuracy estimates are not available for this CORS
DR8389.because its coordinates were determined in part using modeled
DR8389.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR8389.and ellipsoid height can be obtained from the short-term time series.
DR8389.Additional information regarding modeled velocities is available on
DR8389.the CORS Coordinates for MYCS2 web page:
DR8389.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR8389
DR8389.The coordinates were established by GPS observations
DR8389.and adjusted by the National Geodetic Survey in September 2022.
DR8389
DR8389.NAD 83(MA11) refers to NAD 83 coordinates where the reference frame has
DR8389.been affixed to the stable Mariana Tectonic Plate.
DR8389
DR8389.The coordinates are valid at the epoch date displayed above
DR8389.which is a decimal equivalence of Year/Month/Day.
DR8389
DR8389.Due to the release of the International GNSS Service (IGS) 2014
DR8389.realization of the International Terrestrial Reference Frame of 2014
DR8389.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR8389.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR8389.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR8389.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR8389.currently published epoch of 2010.00.

DR8389.The XYZ, and position/ellipsoidal ht. are equivalent.
DR8389
DR8389.The ellipsoidal height was determined by GPS observations
DR8389.and is referenced to NAD 83.
