Problems solved by technology

[0003] Due to the influence of environmental factors, GNSS signals generate multipath interference signals such as diffraction or reflection in the process of propagation and transmission, forming multipath effects, which cause the delay and polarization direction of the received signal to change, resulting in positioning deviation Even the signal is out of lock

Abstract

The invention discloses a satellite signal directional forwarding device. The satellite signal directional forwarding device comprises a receiving module, a control module and at least a directional transmitting antenna; the receiving module and the control module are arranged on the top of a building; the control module is connected between the receiving module and the directional transmitting antenna and is used for receiving satellite signals processed by the receiving module, adjusting the amplitude of the satellite signals, and transmitting the adjusted satellite signals to the directional transmitting antenna; and the directional transmitting antenna is disposed on the side surface of the building so as to directionally transmit the adjusted satellite signals. According to the satellite signal directional forwarding device of the invention, the receiving module is adopted to receive and process the satellite signals and transmits the processed satellite signals to the control module for amplitude adjustment; the directional transmitting antenna is adopted to transmit the adjusted satellite signals; and therefore, the building will not block and interfere the signals, and thedistortion-free directional forwarding of navigation signals can be realized.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite signal directional forwarding device. Background technique [0002] Global Navigation Satellite System (GNSS for short) is widely used because of its global coverage, all-weather, high precision, automation, and high efficiency, and has become one of the fastest growing information industries in the world. However, GNSS receivers work It is inevitable that the measurement error will be caused by the surrounding environment and its own interference. When the interference error is serious, the receiver will not work normally. The main error sources in measurement and positioning are satellite clock error, satellite ephemeris error, ionospheric delay error, tropospheric delay error, receiver noise error, thermal noise and multipath interference error, etc. With the improvement of GNSS system modernization and the development of receiving technology, many...
