will be able to identify the aircraft black box belongs.Black Box battery can theoretically support a month,boutique louboutin pas cher, and now Australia detected signals are intermittent,air max femme, does that mean that the battery is already depletion? Development Research Center of China National Offshore Yu Zhirong told the “Global Times” reporter,nike tn soldes, due to a water depth of 4000-4500 m search and undersea ridges,tn nike pas cher, volcanoes,louboutin homme pas cher, ocean waves and other complex marine environment will affect the reflection and transmission signals, this is when the signal is weak and off renew reason.
Foreign detection equipment does gapsAfter the “Coast Guard 01” boat on the 5th announced in China received the frequency emitted by the black box suspected of 37.5 kHz pulse signal,parajumpers homme, the Western media is filled with a lot of respect, “China, placed on a small black box rescue boats will be able to search logger challenged to find a signal? “the. Chinese experts explained,hollister, “Coast Guard 01” carry several sets of sea measuring equipment, including black box search the best instrument of underwater depths of 2,nike tn,000 meters, the maximum depth 5000 meters, so it is indeed possible to monitor the seabed signal. However,woolrich parka 2014, considering the depth of 4000-4500 m searching the waters, has been close to the detection limit of the device, so the limited accuracy of the detector.By contrast, the participation of the British Navy search “echo” spacecraft itself is designed specifically for the hydrographic survey ship.
equipped with multiple-beam echo sonar, marine towed sonar,hollister milano, acoustic Doppler current profilers and other specialized equipment. 7 morning, four Chinese ships and the British “echo” in the waters of a suspected black box signals received are reviewed sweeping survey, due to “echo” No. 6-10 knots can be dynamically sweeping survey, so its detection range more large,boutique louboutin paris, more efficient.Australia “Sea Shield” No survey ship before performing the search mission, but also the emergency placement of the United States “Bluefin -21” Autonomous underwater vehicle and TPL-25 towed sonar. TPL-25 which has been involved in 2009 Air France A330 crashed plane searching the maximum depths of up to 6100 meters. Chinese naval expert Li Jie 7th “Global Times” interview,parka woolrich uomo, said that compared with the Chinese vessel equipment.
US TPL-25 can accurately adjust the working depth as required, in order to avoid the impact of waves, currents,nike air max, floating debris,Giuseppe Zanotti Sneakers, such as the transmission of signals Therefore a more accurate detection result. According to the CNN report on the 7th, “Sea Shield” was originally on the 6th 300 meters underwater to detect suspected signal,cheap toms sale, the detector dive to 1400 meters and found the signal becomes stronger, lasts 2 hours and 20 minutes.Australia received signal is unlikely to be the same sourceChina and Australia, where it was found as a result of signal 600 kilometers away, Li Jie said that even taking into account the influence of ocean currents and other factors,toms, the black box signal transmission distance in the sea is not more than 100 km,moncler outlet milano, and therefore unlikely to be found in Australia is the same source . But in the end which the signal from the MH370 need verification. According to reports, every passenger aircraft black box waveform signal is specific,doudoune parajumpers, it would be with the American Boeing company’s data for comparison.
