Depth rated to 1,000 metres,
the SST can be used with most makes of USBL system but offers
additional benefits when working with Sonardyne's successful
'Fusion' technology. As these systems measure both range
and bearing, only one overhead pass is required to position
the transponder instead of the two passes currently required
for range-only transponder systems. This results in considerable
savings in vessel time and introduces a new standard of
efficiency to seismic operations.
Another feature of the
transponder is its programming flexibility. Any one of 410
addresses and 16 reply channels, providing 6560 identities,
can be programmed using a Type 8037 MF Command Unit. This
lends itself to the marking of seismic cables and other
applications demanding dense coverage.
The SST can also be used
as a permanent long-life marker transponder, or a small,
low-cost USBL tracking beacon for small ROVs.
