The Russian Space Agency Roscosmos plans to build in the United States six ground stations, correct the error of navigation satellites. U.S. intelligence agencies are opposed to a permit, allegedly because of the threat of espionage.
U.S. intelligence agencies and the U.S. Department of Defense brace themselves against the fact that Russia's space agency may build six correction systems for the navigation system Glonass on U.S. soil. The U.S. government must now decide on a request by Russia from May 2012. According to " New York Times ", the CIA and other U.S. intelligence agencies put across, other ministries apparently planned to comply with the desire of Russia. Because of the dispute in the U.S. government's decision has now been pushed out again.
The U.S. intelligence justify the resistance as:
The ground stations would improve the precision of the Russian navigation satellite system, and thus the accuracy of Russian arms.
The ground stations could be used for espionage.
The espionage accusation seems far-fetched. Ground equipment for the correction of navigation satellite systems can operate either in the province, far from cities and interesting radio links. The U.S. intelligence agencies around the world use their centrally located Embassy building in capitals for spying of communication. Installations on flat land should be very difficult to harness for something. Apart from that expected ground stations for the correction of navigation satellite systems hardly fall under diplomatic protection as the espionage systems of Americans worldwide.
Ground stations to correct turbulence
It is undisputed, however, that more ground stations would improve the precision of the Russian Glonass system - what they're there eventually. Navigation satellite systems without correction mechanisms are not particularly accurate. This is mainly due to the interference of the signals in the atmosphere. A GPS or GLONASS receiver determines its position by receiving signals from at least three satellites and together account. But these signals are deflected by turbulence in the outer atmosphere, from hour to hour varies.
The delayed signals change as calculated by the receiver on the ground position. Reference stations on the ground, as they want to build Roskosmos in North America, received at one location are rooted precisely the satellite signals. Because the position is known, can the deviation of the received data to determine accurately. The measurement data of all ground stations is being centralized, one from Calculated correction signal can be transmitted via satellite or online at receiver.
Private providers operate a worldwide reference stations
Reference stations, such as Russia, they now want to build in the U.S., are not uncommon. The United States for their government GPS correction system WAAS (is that used in aviation), for example, in Canada and Mexico ground stations in operation. Russia operates in his own country and in Brazil have long GLONASS reference stations. And private providers have for years worldwide reference stations for the U.S. system GPS and Glonass in operation.
The tractor-Bauer, John Deere has for its correction signal Starfire 40 ground stations, for example, in use worldwide. Companies can determine exactly how OmniSTAR correction signals, Range Point and subscribe Starfire and so to a few centimeters deviation position - that is, for example, for robots in agriculture necessary to retrieve rows of plants.
For the U.S. blockade against GLONASS base stations there could be a third reason. The Russian system is, despite some setbacks for years of reliable and better, many professional systems use Glonass data long to specify the GPS positioning. And in many modern smartphones (eg, iPhone 5, Samsung Galaxy S4) are built Glonass receivers. Should the system be more specific without charge now by additional base stations, it could make the U.S. system GPS serious competition.
Perhaps the blockade of U.S. intelligence also serves economic interests. The Republican U.S. Rep. Mike Rogers, chairman of the Safety Committee, puts it this way: "It is in many ways an advantage for the United States of America, that the world is dependent on GPS."
