DF7984.The coordinates were established by GPS observations
DF7984.and adjusted by the National Geodetic Survey in October 2023.
DF7984
DF7984.NAD 83(MA11) refers to NAD 83 coordinates where the reference frame has
DF7984.been affixed to the stable Mariana Tectonic Plate.
DF7984
DF7984.The coordinates are valid at the epoch date displayed above
DF7984.which is a decimal equivalence of Year/Month/Day.
DF7984
DF7984.Due to the release of the International GNSS Service (IGS) 2014
DF7984.realization of the International Terrestrial Reference Frame of 2014
DF7984.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF7984.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF7984.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF7984.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF7984.currently published epoch of 2010.00.
DF7984
DF7984.Additional information on MYCS2 is available at
DF7984.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF7984
DF7984.The orthometric height was determined by GPS observations and a
DF7984.high-resolution geoid model using precise GPS observation and
DF7984.processing techniques.
DF7984
DF7984.Significant digits in the geoid height do not necessarily reflect accuracy.
DF7984.GEOID12B height accuracy estimate available here.
DF7984
DF7984.The PID for the CORS L1 Phase Center is DR9387.

DF7984.Click photographs - Photos may exist for this station.
DF7984
DF7984.The XYZ, and position/ellipsoidal ht. are equivalent.
DF7984
DF7984.The ellipsoidal height was determined by GPS observations
DF7984.and is referenced to NAD 83.
