Notes
 S610PS   Nav was RTK-GPS.  Yonav, time GMT  
 Only one base station was needed for the Elwha survey.  The OPUS solution 
 for the coordinates we broadcast for the survey is attached.  These 
 coordinates will be revised once the GPS data is post-processed to provide 
 better accuracy.

 OPUS TEXT FILE IN /nav/raw/opus-MILL-2010-052.txt  The writeboard named ""MILL": Elwha SWATH bathymetry survey RTK GPS base station analysis" has been created by Tom Reiss:     The following information pertains to the GPS base station   "MILL" used for the SWATH bathymetry survey at Elwha River   delta (Port Angeles, WA), February-March 2010.   The base station was programmed using the following coordinates: (see   also "elwha-base-setup.JPG")     Reference Frame: WGS84 (G1150)   Epoch: 2010.1548   Latitude: N 48 08' 06.01943"   Longitude: W 123 28' 06.90674"   Ellipsoid Height: -11.355m     The average values for the derived OPUS solution for   "MILL" are:   Reference Frame: ITRF00 [same as WGS84 (G1150)]   Epoch: 2010.1548   Latitude: N 48 08' 06.01936"   Longitude: W 123 28' 06.90685"   Ellipsoid Height: -11.351m     The differences to be added to the RTK broadcast locations are:   Latitude: -0.00007"   Longitude: +0.00011"   Ellipsoid Height: +0.004m     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: 5331411.376m   Easting: 465138.251m   Ellipsoid Height: -11.042m   Orthometric Height: 9.155m (based Geoid09)     The average values for the derived OPUS solution for   "BEL1" are:   Reference Frame: NAD83, UTM zone 10   Epoch: 2002.0000   Northing: 5331411.374m   Easting: 465138.249m   Ellipsoid Height: -11.038m   Orthometric Height: 9.159m (based Geoid09)     The differences to be added to the RTK broadcast locations are:   Northing: -0.002m   Easting: -0.002m   Ellipsoid Height: +0.004m   Orthometric Height: +0.004m
