Tuneable and Non Tunable Sound Sources – RAFOS
The develogic sound sources are available with several frequency ranges suitable for RAFOS navigation and acoustic tomography.
Whereas the non tunable sources are factory tuned to customer specification, the tunable TAS type is able to shift its resonance frequency. The frequency shift can be manually preset or automatically optimized to the configured transmission pattern.
RAFOS electronic unit and battery compartments are installed in our standard double-length MCH modular composite pressure housing.
Max. deployment duration of the standard configuration with one standard RAFOS sweep per day is 3 years.
The standard system time base is calibratable to better than 0.1 ppm. Also available is a precision version with Symmetricom SA.45s Rubidium clock offering better than 3×10-10ppm/month ageing performance.
As with all develogic instrumentation, the sound sources also integrate seamlessly with our communication solutions, allowing full remote control and monitoring e.g. via our acoustic modems.
