The underwater vehicle (AUV) - without the main battery can be easily replaced in need of a cable connection - provided the field to extend the deployment time that the required navigation sensors are (additional battery modules are optional). integrated. Sensor interfaces Technical characteristics Standard sensor equipment The »C-Watch« vehicle can easily be „„ „„ „„ „„ „„ „„ „„ tailored for individual monitoring or intervention tasks. It is equipped with open sensor interfaces allowing the integration of different sensor or actuator modules. Customers can select from a range of field-tested sensors or order the installation of own sensors.
