DR3425.Formal positional accuracy estimates are not available for this CORS
DR3425.because its coordinates were determined in part using modeled
DR3425.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR3425.and ellipsoid height can be obtained from the short-term time series.
DR3425.Additional information regarding modeled velocities is available on
DR3425.the CORS Coordinates for MYCS2 web page:
DR3425.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR3425
DR3425.The coordinates were established by GPS observations
DR3425.and adjusted by the National Geodetic Survey in October 2019.
DR3425
DR3425.NAD 83(MA11) refers to NAD 83 coordinates where the reference frame has
DR3425.been affixed to the stable Mariana Tectonic Plate.
DR3425
DR3425.The coordinates are valid at the epoch date displayed above
DR3425.which is a decimal equivalence of Year/Month/Day.
DR3425
DR3425.Due to the release of the International GNSS Service (IGS) 2014
DR3425.realization of the International Terrestrial Reference Frame of 2014
DR3425.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR3425.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR3425.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR3425.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR3425.currently published epoch of 2010.00.

DR3425.The XYZ, and position/ellipsoidal ht. are equivalent.
DR3425
DR3425.The ellipsoidal height was determined by GPS observations
DR3425.and is referenced to NAD 83.
