Tom Reiss will provide broadcasting base coordinates for RTK-GPS
The following information pertains to the GPS base station
"DP01" used for the SWATH bathymetry survey at Deception
Pass, February 2010.
The base station was programmed using the following coordinates: (see
also "deception-base-setup.JPG")
Reference Frame: WGS84 (G1150)
Epoch: 2010.1178
Latitude: N 48 23' 57.74198"
Longitude: W 122 39' 51.06297"
Ellipsoid Height: -18.429m
The average values for the derived OPUS solution for
"DP01" are:
Reference Frame: ITRF00 [same as WGS84 (G1150)]
Epoch: 2010.1178
Latitude: N 48 23' 57.74088"
Longitude: W 122 39' 51.06220"
Ellipsoid Height: -18.411m
The differences to be added to the RTK broadcast locations are:
Latitude: -0.00110"
Longitude: -0.00077"
Ellipsoid Height: 0.018m
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: 5360744.398m
Easting: 524857.664m
Ellipsoid Height: -18.104m
Orthometric Height: 3.939m (based Geoid09)
The average values for the derived OPUS solution for
"SKA1" are:
Reference Frame: NAD83, UTM zone 10
Epoch: 2002.0000
Northing: 5360744.364m
Easting: 524857.680m
Ellipsoid Height: -18.086m
Orthometric Height: 3.957m (based Geoid09)
The differences to be added to the RTK broadcast locations are:
Northing: -0.034m
Easting: 0.016m
Ellipsoid Height: 0.018m
Orthometric Height: 0.018m
