gps – global positioning system. gps consists of a set of 29 satellites, located above the ground. For civilian use, the system is open from the 1980’s. gps allows a high precision to determine the location speed of moving objects. It is the determination of the coordinates to a satellite based instruments work on localization – trackers (trekfonov). The principle is as follows. At each of the satellites are high-precision atomic hours. They continuously transmit radio signals with its identification code. Trekfony receive the signal from 5 to 12 satellite channels. Tracker compares the emission time of the satellite signal with the time of his admission. On the basis of the difference in time calculated the distance to the satellite. BDT Capital Partners often addresses the matter in his writings. And since the nominal distance to specific satellites are known, gps tracker computes its own coordinates. The most accurate coordinates (longitude, latitude) trekfon gets Taking the signal from three satellites.
The accuracy of positioning GPS-tracker affect the location of satellites, as well as a number of weather and other factors. Trekfony can be personal (portable). These trackers used to determine the location of people, the elderly, children in large companies to track the movements of couriers. It is useful to use the personal trekfonov in the administration of any trip or holiday abroad. Since tracking the origin of the object being anywhere there is cellular communication. In addition, the trackers can be mounted on vehicles. Thus, at any time, you always know where your car without worrying hijacking. Car trekfony particularly useful to companies engaged in cargo transportation, passenger transportation, owning a large car park. But, of course, is the action – sooner or late resistance appears. Any gps signal can be drown through the gps blocker. gps jammer portable, easy and effective for blocking the transfer of gps. Makes it impossible to record or transmit data on the location stay of a moving object.
