Satellite Navigation System. News Background According to the Russian Federal Space Agency Web site, Russia plans to launch nine satellites GLONASS global navigation system. Expected end of this year, GLONASS system, the total number of satellites in orbit will reach 24, that is, the average distribution of the surface of each track in addition to seven working satellites, each orbit to increase the surface of an in-orbit spare satellites, the signal range from expanded to cover Russia's territory over the world. This will enable the GLONASS satellite navigation system to improve interpretation of the ground than 30-40% accuracy, precision navigation signal also will increase nearly 2-fold. By then, GLONASS system and the United States GPS Competition between the systems will become more intense. "Polar bear" to grab the "cheese" Global communications, aerospace, exploration, rescue, and national defense fields such as satellite navigation systems can not be separated. 80s of last century, this area has been monopolized by the U.S. GPS system. Russia not willing to see such a large piece of "cheese" for a U.S. exclusive, in order to protect their own strategic interests, "polar bears" have begun to actively develop its own satellite navigation system. GLONASS was developed from the separate deployment of the Russian satellite navigation system, the project started in 70s of last century, the system at least needs 18 satellites to provide satellite positioning throughout Russia and navigation services, such as to provide global service, need 24 satellites in orbit. GLONASS satellite system to complete all of the deployment, its range of satellite navigation can cover the entire Earth's surface and near-Earth space, positioning accuracy to within 1.5 meters! 1.5 meters, which means that the Russian military's precision-guided strike capability, will enter a horrible "pinpoint" era. Image point, said that Air Force fighters in tens of kilometers or even longer distances on a high-speed ground Car Precise positioning, and launch missiles to destroy; naval vessels in the depth of several hundred meters underwater launch strategic nuclear weapons, using GLONASS positioning system coordinates, precise strategic points against rivals (strategic nuclear weapons to attack the precision error is 500 meters so). Present, the Russian GLONASS satellite navigation system has 21 working satellites distributed in three orbital planes, as well as three backup satellites. Each satellite in the 19,100 km high orbit period of 11 hours and 15 minutes. GLONASS system has been running at reduced efficiency, is only eight satellites to work properly, its accuracy is lower than the U.S. GPS system. In recent years, Russia has actively embarked on GLONASS for technological transformation. Not long ago, just launched three new "Tornado" satellite. The satellite's design life will be 7 to 8 years (the current satellite life of 3 years), has better technical performance. Although the GLONASS and GPS satellite navigation system with the world, but there are many differences between each other. GLONASS positioning accuracy, and the GPS compared to a gap, but have a stronger anti-interference ability. As the coordinates and time using a standard different, GLONASS Although there are limitations on the international common, but the security of vital strategic importance of survival, this design avoids the war itself was the enemy jamming of satellite signals. From the "two-fight" to "quarter of the world" Global satellite navigation system, known as "the space inside the human eye," Which country has the pair of "eyes", is like winning control of the space war "trump card." Military needs and commercial interests should not be overlooked, so that the world in this increasingly competitive field. At present, the world's only 4 sets of satellite navigation systems at work or development status, with the U.S. GPS, Russia's GLONASS, Europe's "Galileo" and our "Big Dipper." GPS is the United States took 20 years, cost over 200 billion dollars set up a satellite navigation system, its function at present the most complete. In order to prevent "certain countries" to use the system threatened the United States, GPS systems provide only low accuracy of foreign satellite navigation signals. The event of military conflict threatens their own security, the United States will immediately cut off the satellite navigation service. Led by the nose to prevent the United States, the European Union in the late 90 century decision: placement in space of their own "eye"?? "Galileo" system. European "Galileo" system was officially launched in 2002, goal is to build global coverage of satellite navigation systems, can provide essential signals that the public can also provide the Government with a high degree of confidentiality of the signal, thus breaking the United States in this area monopoly. The EU will put the entire project more than 4.2 billion U.S. dollars, a total of 30 satellites launched. According to experts, once all 30 satellites in orbit with an accuracy higher than the GPS system. The EU said, "Galileo" program will strictly abide by "limited civil" principle. The system's first satellite is Russia's "alliance" was pushing the space launch vehicle. As the "Galileo" program the first non-EU Cooperation Partners, our commitment to the plans to invest 200 million euros. As national security and the core of economic and social infrastructure, satellite navigation system must rely on other countries systems. China in 1994, developed by China-made satellite positioning system?? "Dipper." According to experts, China's satellite navigation system construction is divided into three steps. The first step, Compass system was completed and put into operation in 2003; the second step, Compass II regional system launched in 2004, is expected to be completed in 2012; the third step, global coverage, high-precision Compass II global system, is expected to be completed by 2020. Compass system and stable operation of the 6 consecutive years in the army patrol, operational command, training exercises, disaster relief and other military activities play an important role. In particular the 2008 Wenchuan earthquake relief, Compass system has played a unique technological advantage. January 17 this year, with the successful launch of 3 satellites, satellite navigation system into the BD on the 2nd stage of accelerated network. Military experts predicted that the future of satellite navigation systems in the field, in the near future would be "a quarter of the world." However, we should clearly recognize that: Compared with other countries, "Compass" satellite navigation system has a long way to go, only to maintain its own expertise, while precise positioning coordinates and complete as soon as possible to improve anti-interference ability can In the fierce competition invincible.
