Datasheet
SIPS 2 HGPS Transceiver
Description
A key component in Sonardyne’s
SIPS System, HGPS (Head and Gun
Positioning System) transceivers are
intelligent, shock-mounted acoustic
devices designed to position seismic
sources and tailbuoys.
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.
Key Features
• Direct power from topside
equipment
• Compatible with XSRS transceivers
• Choice of right-angle and remote
transducers
• Shock mounted electronics to
withstand harsh operating
environments
• Capable of receiving 16 ranges
per cycle
• Designed to transmit to an
unlimited no of units
• Flash upgradeable firmware
