Notes -
The navigational system used on the R/V ALOHA cruise, A1-90-WO, was an
IBM 386 PC based system using inputs from an ASHTECH (MODEL #) gps receiving
unit and a DECCA 540 delnorte transponder ranging system. Delnorte was used for
the majority of the cruise because of its higher degree of positioning accuracy
being replaced by gps only when the ship was out of range of the land based
transponder stations or in areas of poor station geometry, i.e. along baselines
between stations. The positioning accuracy of the delnorte system is about ____
when three or more of the stations are being used for the ranging calculations,
and that of gps about ___________, but can be up to 100 meters when selective
availability (errors introduced into the gps signal by the defense department)
is implemented. Both systems calculate ranges by using electromagnetic signals.
The travel times from the signals are converted into distances and used to
determine the ships position.
GRAIG,
I wasn't sure about the accuracy of the systems at their best, that is
why there are blanks. Also wasn't sure about the model # of the Ashtech.
Similar information is available for thousands
of other USGS/CMG-related Activities.
If known, available are Activity-specific
navigation, gravity, magnetics, bathymetry,
seismic, and sampling data; track maps; and
equipment information; as well as summary
overviews, crew lists, and information
about analog materials.
If available, access to physical samples is
described in the "WR CMG Sample Distribution
Policy" at:
