Tritech Gemini 1200ik
The Gemini 1200ik multibeam sonar operates at two acoustic frequencies, 720 kHz for long range target detection, and 1200 kHz for enhanced high-resolution imaging. The sonar maintains a 120° horizontal field of view when operating at both acoustic frequencies. This allows targets of interest to remain within view at all times.
Description
The 1200ik is designed to operate in harsh and noisy environments. The sonar actively attenuates waterborne electrical noise generated by other subsea equipment, including thrusters, to avoid the detrimental impact of such noise on the sonar image. An integrated velocity-of-sound sensor ensures that targets are displayed to a high degree of positional accuracy. CHIRP processing provides improved target separation over longer ranges.
The 1200ik is fully compatible with Tritech’s software package, Genesis, which improves user interaction and allows for control of multiple Tritech products from within one software package. A software development kit (SDK) is also available for Windows and Linux operating systems.
To allow the 1200ik to share bandwidth with other sensors on a shared network connection, the data bandwidth required by the sonar can be limited by capping the ping rate, reducing resolution, or enabling data compression.
With the same physical size and connection interface as the 720ik, the 1200ik (350 m) offers an easy upgrade path to higher resolution imaging. As with all Gemini products, SeaTec software can be utilised to undertake more advanced decision-based activities. The higher resolution capability of the 1200ik provides an opportunity to perform target classification to a higher degree of accuracy than previously
