1. Place the ROV in the water, start tracking and invoke the noise test feature. (see chapter4 for details on how to operate the noise test).2. Maneuver the ROV next to one of the surface station transducers (or even clip surfacestation transducer #1 to the ROV for this initial test)3. Monitor noise levels as ROV thrusters and other loads are activated.4. Make sure the noise never exceeds the maximum permissible amount of 120 dB. If itdoes, selectively switch all the ROV loads off until the noise level drops. Try moving themountingposition of the mobile station away from the noise generating device. If thatdoes not work, contact Desert Star or the ROV manufacturer for advice.4. Setting Up the SystemOverview: This section explains how to mount the surface station transducers in their correctplaces, tell the DiveBase software where they are (relative to the ship or dock). Followingdeployment of the surface station transducers, activate and deploy the mobile station and check forany interfering background noise.Deployment Tasks1. Deploy the surface station sonar transducers over the side of the ship, dock or dam2. Enter surface station sonar transducer positions relative to each other in the DiveBasesoftware3. Check and enter underwater visibility to define the width of the position ‘painting trace’4. Activate and deploy the mobile station5. Conduct a noise testGood Transducer Mounting Is Key To Optimizing PerformanceThe sonar transducers are the antennas of your surface station. It is important that the transducersare mounted stable, clear of noise sources, and with sufficient distance from each other. The qualityof transducer mounting will directly affect the accuracy and range of PILOT. We strongly urge you toread, and understand, the information in this section.The PILOT surface station connects to three sonar transducers. The transducer connectors arelabeled Sonar #1, Sonar #2 and Sonar #3 on the surface station. The transducers serve as thereference for navigation. While there are many ways to mount the sonar transducers, werecommend that you standardize on the general configuration shown below. Using always the samerelative layout minimizes the chance of confusion. Figure 7.1 gives a birds eye view of thedistribution of three sonar transducers on a vessel. |
