HGPS units are designed to
mount on airgun arrays, buoys, towfish and vessels and can
be supplied with different transducer arrangements to accommodate
an operator's preferred deployment method
.
HGPS Transceivers are hard wired into individual channels
on the SIPS2 Controller cards and do not need batteries.
A two wire D.C. differential system with a floating ground
powers the HGPS units.
The communications are superimposed
on the D.C. level this is the same as that used by XSRS
transceivers.
Each HGPS/RTS Controller card
can handle up to eight HGPS Transceivers.
