Our Small Seismic Positioning Transponder 6 (SST 6) is a small rugged transponder for acoustic positioning of ocean bottom seismic cables and nodes, where high-performance, small-size, low-cost and ease of programming are all important operational factors.

Near Field Communications (NFC) allows fast programming of 16 group interrogation addresses and 95 reply channels providing more than 1520 unique acoustic identities. This allows the marking of seismic cables and other applications demanding dense transponder coverage.

The SST 6 is easily and quickly configured using NFC with a suitable NFC enabled handset (including an NFC enabled Android™ handset with the Sonardyne NFC App) or a dedicated HF Radio Frequency Identification (RFID) reader.

Operating in the Medium Frequency (MF) band makes it compatible with Sonardyne’s Ranger 2 Wideband Nodal USBL systems.

These USBL systems measure both range and bearing to SST 6 in the same operation so an accurate position of the node or cable can be determined very quickly and at a high update rate.

Combining the use of Ranger 2 USBL and SST 6 in this way results in considerable savings in vessel time and new standards of efficiency for seismic operations.

Sonardyne Wideband acoustic signal processing offers improved performance in challenging conditions such as at long range, high elevation and long layback tracking, with performance diagnostics provided for quality control.

Sonardyne Wideband signal encoding also reduces the interference both on and by adjacent Sonardyne and other acoustic positioning systems.

The NFC link provides the ability to enter SST 6 into a storage mode when not in use, thereby significantly increasing the overall battery endurance.
