AJ5871.The coordinates were established by GPS observations
AJ5871.and adjusted by the National Geodetic Survey in June 2021.
AJ5871
AJ5871.NAD 83(PA11) refers to NAD 83 coordinates where the reference frame has
AJ5871.been affixed to the stable Pacific Tectonic Plate.
AJ5871
AJ5871.The coordinates are valid at the epoch date displayed above
AJ5871.which is a decimal equivalence of Year/Month/Day.
AJ5871
AJ5871.The current NAD 83 position and ellipsoid height were revised in
AJ5871.February 2013 to account for displacement due to the September 29,
AJ5871.2009 Samoa Island earthquake.
AJ5871
AJ5871.Due to the release of the International GNSS Service (IGS) 2014
AJ5871.realization of the International Terrestrial Reference Frame of 2014
AJ5871.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ5871.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ5871.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ5871.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ5871.currently published epoch of 2010.00.
AJ5871
AJ5871.Additional information on MYCS2 is available at
AJ5871.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ5871.** The heights of stations in this area may have changed
AJ5871.** by more than 10 cm due to earthquakes. NGS strongly warns
AJ5871.** against the use of such suspect heights as control.
AJ5871
AJ5871.The orthometric height was determined by GPS observations and a
AJ5871.high-resolution geoid model using precise GPS observation and
AJ5871.processing techniques.
AJ5871
AJ5871.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ5871.GEOID12B height accuracy estimate available here.
AJ5871
AJ5871.The PID for the CORS L1 Phase Center is DK7460.

AJ5871.Click photographs - Photos may exist for this station.
AJ5871
AJ5871.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ5871
AJ5871.The ellipsoidal height was determined by GPS observations
AJ5871.and is referenced to NAD 83.
