S910SF The writeboard named "Corte Madera survey control (CM01; RTK GPS base station)" has been created by Tom Reiss:
The following information pertains to the GPS base station
"CM01" used for the SWATH bathymetry survey at Corte
Madera (San Francisco Bay, CA), March 2010.
The base station was programmed using the following coordinates: (see
also "CM01-base-setup.JPG")
Reference Frame: WGS84 (G1150)
Epoch: 2010.0630
Latitude: N 37 54' 51.37721"
Longitude: W 122 29' 13.21809"
Ellipsoid Height: 88.829m
The average values for the derived OPUS solutions for
"CM01" are:
Reference Frame: ITRF00 [same as WGS84 (G1150)]
Epoch: 2010.1532
Latitude: N 37 54' 51.37819"
Longitude: W 122 29' 13.21786"
Ellipsoid Height: 88.780m
The differences to be added to the RTK broadcast locations are:
Latitude: +0.00098"
Longitude: -0.00023"
Ellipsoid Height: -0.049m
Using UTM coordinates as a comparison:
The base station was programmed using the following coordinates:
Reference Frame: NAD83, UTM zone 10
Epoch: 2002.0000
Northing: 4196426.796m
Easting: 545093.600m
Ellipsoid Height: 89.359m
Orthometric Height: 121.700m (based Geoid09)
The average values for the derived OPUS solutions for
"CM01" are:
Reference Frame: NAD83, UTM zone 10
Epoch: 2002.0000
Northing: 4196426.825m
Easting: 545093.607m
Ellipsoid Height: 89.310m
Orthometric Height: 121.651m (based Geoid09)
The differences to be added to the RTK broadcast locations are:
Northing: +0.029m
Easting: +0.007m
Ellipsoid Height: -0.049m
Orthometric Height: -0.049m
