Antennas of satellite navigators are located on the laboratory building roof, with the result that dynamic navigation training items are unable to be carried out. By mounting WiFiRS232 transparent transfer modules to satellite navigators, the master computer wirelessly broadcasts dynamic navigating data comprise of position, course, speed, and satellites information instead of these from OEM boards to the display control panel, stimulating the navigators to work in predefined sailing scenes, so that experiment courses lean close to combat cardinal lines. The method promoted efficacies of now available laboratory equips for low cost without damages, and it’s extremely practical for enhancing working ability of navigation specialty trainees.
