Background
At present, the Beidou satellite covers Asia-Pacific areas comprehensively, and the global coverage is about to be realized. The Beidou communication machine is mainly an omnidirectional antenna, so that data can be transmitted and received, the communication function of Beidou can be completed by only one satellite during data transmission, and the Beidou positioning function can be realized by two or more satellites. The communication means of the ocean buoy basically realizes a Beidou communication machine as a data sending and receiving platform. And sending the data acquired by the marine buoy to a ground receiving station through a Beidou communication machine.
However, in recent years, people find that the Beidou communication machine is easy to interfere to cause the loss of Beidou data receiving, and analysis can find that:
at first, the big dipper receiving frequency channel is 2492MHz, and this frequency channel is close WIFI2.4G network signal, and big dipper communication machine received signal is comparatively sensitive itself, and consequently, big dipper communication machine receives the WIFI signal interference of mounted position easily, and then influences big dipper data acceptance rate, causes the disappearance of data.
Secondly, extreme weather (when typhoon crosses over the border) can also cause very big influence to the data reception of big dipper communicator.
And thirdly, the Beidou satellite belongs to a high orbit satellite, the signal intensity is relatively weak, and if the enhancement of the received signal of the Beidou communication machine can be realized, the Beidou data receiving rate can be greatly improved, so that the instantaneity and integrity of Beidou data receiving are guaranteed.
However, no relevant mature technology can be used for reference at present.
