LinkQuest's
Precision Marine Geodetic systems provide
accurate acoustic positioning over a long range. The
systems, designed for demanding applications such as
seafloor movement monitoring, offshore vessel and survey
positioning and defense operations, are capable of
accurate positioning within 0.5 cm for up to 7000 meters
in range. These systems have been extensively deployed in
the field and successful results have been
generated.

Using
leading-edge "Broadband
Acoustic Spread Spectrum Technology",
accurate sound wave traveling time between LinkQuest's
subsea precision transponders and surface station can be
measured. When the system is integrated with a Kinematic
GPS, motion sensors and a gyro on the surface vessel or
undersea vehicle, sub-centimeter acoustic positioning can be
achieved.
Conventional acoustic positioning systems needed extended
high frequency (50 to 100 kHz) to achieve accuracy no more
than 5 cm. The high frequency severely limits the range the
system can reach due to heavy water absorption loss. Unlike
conventional systems, LinkQuest's innovative Precision
Marine Geodetic Systems operate from 7.5 to 12.5 kHz to combat
water absorption loss over long ranges. With this new
technology, no more compromises has to be made between range
and accuracy for underwater acoustic positioning.
Please contact us if you have any application requiring long
range accurate acoustic positioning. There is nothing
else like this commercially available! |
