With the development of satellite navigation systems, satellite navigation is inseparable from many places in life. For example, our common in-vehicle navigation, and some more industrial fields mainly include geographic data collection, high-precision measurement, vehicle monitoring and dispatching and navigation services, as well as applications in aviation and navigation applications, navigation and positioning systems and our lives. Constantly deepening the connection, is also constantly affecting our lives.
The generation of Beidou GPS signal transponder
When using products related to satellite navigation systems, a problem often encountered is the quality of satellite signals. Because in some places, in terms of receiving signals, there will be weak signals, which will have a certain impact on the progress of related work. For example, in some places with more obstacles, it will affect the reception of satellite signals. As a result, satellite signal transponders appear and effectively solve the problem of signal weakening. The editor simply takes the Wright Technology Beidou GPS signal transponder as an example to understand the principle and application of the satellite signal transponder.
The principle of satellite signal transponder
The satellite signal transponder is mainly composed of four parts: outdoor GNSS receiving antenna, low-loss cable, indoor GNSS transmitting antenna, and GNSS satellite navigation signal controller. The main working principle is: the received outdoor satellite navigation signals are processed by amplification, filtering, etc., and then wirelessly forwarded to the laboratory in real time. This is the main working principle of Beidou GPS signal transponder.

Summarize
Satellite signal transponders play an indispensable role in Beidou and GPS navigation equipment. In people’s lives, navigation and positioning products have been increasingly used in shopping, dining, travel and other aspects. For example, with satellite signal transponders, car navigation will obtain better satellite signals, making positioning and navigation more convenient.
