The efficient monitoring region of super short baseline (USBL) systems strongly pertains to the safety of autonomous underwater vehicles (AUVs). This problem has not been analyzed previously. A technique for determining the efficient monitoring place using acoustic theory is suggested. Ray acoustic equations are used to draw rays, which determine the efficient place. The sonar equation is established to find out the available variety of the USBL system and the background noise level using sonar features. The available variety describes a hemisphere-like housing. The overlap of the efficient place with the hemisphere is the efficient position for USBL systems monitoring AUVs. Lake and sea trials show the suggested method's credibility.
A short baseline (SBL) acoustic positioning system is one of three wide sessions of marine acoustic positioning systems that are used to track marine automobiles and divers. The other two is Ultra Short Baseline (USBL) and long baseline systems (LBL). Like USBL systems, SBL systems do not require any seafloor installed transponders or equipment and are thus appropriate for monitoring marine objectives from boats or delivers that are either attached or underway. However, compared with USBL systems, which offer a fixed perfection, SBL positioning perfection improves with transducer place. Thus, where place permits, such as when working from larger veins or a docking station, the SBL system can achieve a perfection and position sturdiness that is similar to that of seafloor installed LBL systems, making the system appropriate for high-accuracy survey work. When working from a smaller boat where transducer place is limited (i.e. when the baseline is short), the SBL system will display reduced perfection.
Modern ROV Lights & Cameras have the capability of carrying 10 TV cameras and working 5 or more at the same time. With the appearance of components such as Central Technologies' fibers optic movie and information multiplexer, up to 8 uncompressed video systems and 15 bi-directional information systems may be transmitted on one single-mode visual fibers. ROV umbilicals may carry up to 12 fibers, of which several are specific as spare parts in case of damage.
Closed circuit television/video systems, unlike with film type photography equipment, provide real-time reviews and certification to the operator—an absolute necessity for direct operator control of the system. Although pictures obtained do not have the very great quality available with printed photography pictures, the owner has the warm feeling that he does have good certification of the object being examined without the concern of returning to the site because of an issue with the photography camera. And, the new frame gets technology can give the operator a hard copy of the video image, at the same time at a lower quality than other systems.
