Military communication technology rapid development

In nineteenth Century, after 30 years, with the development of science and technology, technology of military communication and means to produce a series of fundamental revolution. In 1837 American Morse invented the electromagnetic telegraph and the first row combination of the Morse code, triggered the first technological revolution in the development history of military communication; 1895 Italian Marconi and Russian Popov successfully conducted the radio communication test, caused the second technology revolution in the history of the development of military communication; the two World War, radio communication technology to realize three breakthroughs: in 1923 to achieve a shortwave communication; in 1931 to achieve a microwave communication; in 1936 the establishment of the ultrashort wave relay communication; the former Soviet Union in 1957 took the lead in launching its first man-made earth satellite, military communication then entered the satellite space communication era. In particular, a series of revolution with the rise of the integrated circuit technology and later computers, communications satellite and network technology and the unprecedented development, realize the great leap of human information technology makes the century, become individual combat weapon platform combat multiplier.

The position of the modern battlefield GPS

In twentieth Century, American had started to build the GPS system in the "Star Wars". Now, any point on the earth, any moment can receive a signal from a satellite from orbit, and 3D positioning accuracy, speed and accuracy, time accuracy of an unprecedented increase. Until today, take the positioning system in a number of new U.S. military action and have played an important role. Through the GPS system, the headquarters can grasp the front troops mission location, individual can by virtue of its own information platform in the face of danger, can quickly report accurate range their recourse to force, the timely request emergency air support; air standby support fighter, can quickly and accurately provide high precision rescue. In 1995, Russia has completed the plan space positioning for their own projects, so that the individual combat capability has been significantly enhanced. It is reported, the European Union recently invested a huge sum of money to start a "Galileo" satellite navigation system, the plan will be completed in 2008 and put into use.

Information system of individual weapon combat platform mostly using a small computer and wireless electronic system structure, it uses the global positioning system satellite receiver miniature, provide the specific location of the computer, at the same time can provide the location of the other soldiers, to cooperate with each other between the status of battlefield combat soldier, panoramic view, "stick out a mile". Due to the comprehensive guidance technology breakthrough, the signal to overcome the global positioning system is vulnerable to the obstacle and radio interference caused by missing.

Signal communication

In 1983, the space shuttle, USA Columbia execute STS-09 task, the SAREX team (Shuttle/SpaceAmateurRadioExperimentteam) to the W5LFL/ Erwin Garrett (OwenGarriott) became the first amateur radio astronauts in space. Erwin was using a table Motorola2 meters FM interphone and a pair of mounting on the window antenna. "This is W5LFL in the shuttle Columbia number call..." Erwin, in the STS-09 shuttle mission of spare time, hundreds of QSO and amateur radio station on earth, created the amateur radio contact in human space in history. From then on, amateur radio group of countries, which USA SAREX, Germany's SAFEX, Russia's MIREX as the core of the team, developing in the America shuttle, the Russian space station Mir on amateur radio communication equipment.

Biology

USA scientists recently announced, they have developed a new technology capable of wireless remote control of insects.

California includes scientists University says, the beetles implanted electrodes and radio signal receiving device for the rhinoceros beetle in a kind the name, they have been able to carry out remote control movement of wings and other parts of the body of the insect. According to the introduction, in total the researchers in a unicorn beetle's brain and muscle tissue implanted six micro electrode. In addition, they also set up a beetle body to these electrodes radio data transmission module (consisting of micro controller and battery). Prior to this, the experts of the University was through stimulation of current direct control is realized by the action of insects, and through radio signals to control insect behaviors or for the first time. The scientists explained, the reason to choose the rhinoceros beetle as the transformation object, because the strength of this beetle is relatively in the same volume can carry large insects, up to 3 grams of heavy objects.

The total weight of all the equipment installed in the beetle's body only about 1.3 grams, and will not cause serious obstruction to the action. In the future, the scientists also plan to install special observation apparatus includes a camera, in its body. Because each beetle can afford a weight of 3 grams, so they are in addition to control equipment, also can be in carry 1.7 gram weight sensing equipment.

In the development of the control technology about the purpose, the scientists say, this is to let these beetles to replace some dangerous work the human might afford.

Scientists think, mass production of the control beetles will benefit from human. At the same time, because the electrode arranged on a unicorn beetle body does not need too high precision, so mass production "controlled beetle" fully able to achieve in the short term.
