Description

Technical Field

[0001] The utility model relates to the technical field of signal monitoring, in particular to a civil aviation interference signal monitoring and receiving device. Background Art

[0002] Since civil aviation navigation satellites are 20,000-30,000 kilometers above the ground, their satellite signals are very weak, usually 20dB lower than the noise. Therefore, they are extremely susceptible to various malicious and unintentional interference, including jammers, spoofers, GNSS repeaters, pseudo-satellites, etc. These interferences often lead to emergency go-arounds, aborted approaches, alternate landings, and downgraded use of key air traffic control equipment. These not only bring serious aviation safety risks, but also interfere with the normal operation of air transportation, resulting in flight delays and reduced operating efficiency. Therefore, it is necessary to use civil aviation interference signal monitoring and receiving equipment to find the source of the interference signal and remove it to ensure aviation safety.

[0003] However, existing civil aviation interference signal monitoring and receiving equipment is generally directly exposed to the air. Long-term exposure to wind and rain will cause some components to rust and corrode, reducing their service life and may also cause equipment damage, resulting in serious economic losses.

[0004] To this end, we provide a civil aviation interference signal monitoring and receiving device to solve the above problems. Utility Model Content
