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. 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 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. Each HGPS/RTS Controller card can handle up to eight HGPS Transceivers. Sonardyne UK (Head Office) T. +44 (0) 1252 872288 F. +44 (0) 1252 876100 E. sales@sonardyne.com www.sonardyne.com Specifications SIPS 2 HGPS Transceiver Feature Operating Frequency Receive Sensitivity (Controllable) Source Level (Controllable) Immunity to Multipart System Sync Resolution Acoustic Range Resolution Number of Receive Channels Number of Tone Acoustic Signals Number of Digital Acoustic Signals Weight in Air Weight in Water Type 7888 Sonardyne EHF (60-110kHz) 73dB ref 1µPa @1m Maximum 193dB ref 1µPascal @1m System can resolve bottom bounce/surface bounce greater than 0.3m 75mm @ 1500ms Vp 5mm @ 1500 ms Vp 4 6 60 13.5kg (HGPS Right Angle Transceiver 7888) 9kg (HGPS Remote Transducer Transceiver 7887) 10kg (HGPS Right Angle Transceiver 7888) 6kg (HGPS Remote Transducer Transceiver 7887) Note: Transceivers can transmit and receive in same event allowing for multiple observations to be collected faster.
