Abstract

The GPS signal covering equipment includes GPS signal source, antenna, filter, amplifier and indoors covering system. In order to introduce GPS signal source, the installed outdoor receiving antenna is connected to filter, amplifier and the indoors covering system in sequence. Introducing GPS signal from wide place, where there is no shielding object for viewing sky directly, the invention magnifies GPS signal and covers place, where GPS signal is needed. Advantages are: (1) capable of amplifying GPS signal, increasing efficiency of GPS receiving device; (2) GPS signal covers place, where there is no GPS signal before such as in doors, or in place of having strong electromagnetic interference; (3) large covering area of signal and good effect.

Description

technical field [0001] The invention relates to a technical device that introduces a GPS (Global Position System) signal from an open place that can directly look at the sky without shielding, and amplifies and covers the GPS signal to a designated area that needs to use the GPS signal. Background technique [0002] In recent years, with the promotion of GPS global positioning technology, the scope of application of GPS has become wider and wider, and it has many applications in positioning and navigation, geographic surveying and mapping, and self-help tourism. And various applications gradually increase the requirements for GPS signals. Because the strength of the GPS signal itself is relatively weak, in some areas with a small visible sky area, there are few or no GPS satellites in the visible sky, so the GPS signal is basically not received. In addition, due to the weak GPS signal reaching the ground and the weak ability to penetrate obstacles, i...
