This paper describes the integrated marine acoustic
controller system (IMACS), a system that provides automated concurrent
operation of multiple sonar integrated onto a single survey platform. The
system avoids issues of sensor crosstalk by scheduling the transmit-receive
cycles through an environmentally adaptive approach in a noninterfering
fashion. By dynamically adapting the triggering of the payload sensors, the
system optimises the execution of the seabed mapping survey and improves the
quality of resulting data, thereby significantly increasing survey
productivity. The system's features, design and implementation are presented,
as well as a discussion and initial analysis of the first at-sea trials.
