Description
GunLink is the world’s leading real-time seismic acquisition and source control system. Ranging from the GunLink 2000 which resides as an onboard analogue system, to the GunLink 4000 fully distributed in-water digital system. The GunLink 2500 system sits comfortably in the middle of the existing product range. With an onboard source controller and in-water hydrophone data acquisition, this is the perfect solution for those customers who require digital inputs but are using shorter umbilical lengths (less than 600m).
The system provides onboard firing control and sensor timing monitoring of up to 256 standard guns (128 GI guns) and is capable of receiving in-water hydrophone data from up to 192 near field phones using the Seamap GPM XT.
GunLink 2500 offers true quality control of the array with 24 bit A/D converter sampling at 0.1mS, hydrophone signal acquisition, and recording available as a SEG-D file for post analysis.
New Gun Plate Modules (GPM’s) and telemetry units enable this semi-distributed system to transmit digitised GPM component inputs - hydrophone, depth transducer (DT) and pressure transducer (PT) - locally to the seismic source. The GunLink 2500 therefore offers customers better signal integrity and improved reliability.
The GunLink 2500 system comprises of a Host Computer, Timing Control Unit (TCU) and a number of Gun Control Units (GCU), each capable of controlling up to 16 guns. The TCU generates the system timing signals. Timing is derived from an internal GPS receiver and distributed to the GCUs
