Problems solved by technology

And it is not difficult for those skilled in the art to foresee that the application of the Beidou system will inevitably overlap with the application of the GPS system because they are both navigation systems
However, because the operating frequency of the Beidou system is different from that of the GPS system, the dedicated satellite signal repeater cannot be used in both systems, and the general-purpose satellite signal repeater will introduce interference noise

Abstract

A satellite signal repeater is used for amplifying satellite signals from a satellite navigation system and outputting the satellite signals to a satellite signal receiver. The satellite signal repeater comprises a filter module and an amplifying module, wherein the filter module is used for filtering signals received through a satellite signal input port so as to filter other wireless signals except the satellite signals; the amplifying module is used for carrying out power amplification on the satellite signals of the filter module and outputting the satellite signals undergoing power amplification to the satellite signal receiver through a satellite signal output port. The filter module can be detachably connected between the satellite signal input port and the input end of the amplifying module. Due to the fact that the filter module is designed to be replaceable, the application range of the satellite signal repeater is wide and detection cost and maintenance cost are low.

Description

technical field [0001] The invention relates to a satellite signal repeater, more precisely to a general-purpose satellite signal repeater with enhanced and expanded functions. Background technique [0002] The use of satellite navigation systems is becoming more and more common. In many technological developments, satellite navigation systems are often required to determine position and time. However, if the satellite signal received by the receiver is too weak due to the long feeder line of the receiving antenna, the position and time cannot be correctly resolved, and a satellite signal repeater is needed to enhance the signal. For example, existing GPS signal repeaters have a signal amplification function, but usually do not have a signal power detection function. [0003] On the other hand, as my country's self-developed Beidou satellite navigation system enters a period of rapid development, its application will become more and more extensive. And it is not difficult ...
