Embodiment Construction
[0027] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.
[0028] Such as figure 1 As shown, an anti-interference satellite signal receiver has a fifth antenna 5 that can receive Beidou B1 and / or GPS-L1 signals, and has a fourth antenna 4 that can receive Beidou B3 signals. The output end of the antenna 4 is connected to the input end of the first amplifier, the output end of the first amplifier is connected to the input end of the first SAW filter, and the output end of the first SAW filter is connected to the first power divider The input terminal, the output terminal of the first branch of the first power divider is connected to the input terminal of the second amplifier, and the output terminal of the second amplifier is connected ...

The invention relates to an anti-interference satellite signal receiver, comprising a fifth antenna and a fourth antenna. An output end of the fourth antenna is connected with an input end of a firstamplifier; the output end of the first amplifier is connected with an input end of a first surface acoustic wave filter; the output end of the surface acoustic wave filter is connected with the inputend of a first power divider; a first branch output end of the first power divider is connected with the input end of a second amplifier; and the output end of the second amplifier is connected with afourth signal output port; the output end of the fifth antenna is connected with the input end of a third amplifier; the output end of the third amplifier is connected with the input end of a third surface acoustic wave filter; the output end of the third surface acoustic wave filter is connected with a second branch input end of a second combiner; the output end of the second combiner is connected with the input end of a fourth amplifier; and the output end of the fourth amplifier is connected with a fifth signal output port. According to the anti-interference satellite signal receiver, theanti-interference performance is realized under the interference condition.
Description
technical field [0001] The invention relates to a satellite signal receiver, in particular to an anti-jamming satellite signal receiver. Background technique [0002] The Beidou Satellite Navigation System (BeiDou (COMPASS) Navigation Satellite System) is a global satellite navigation system independently developed and operated by China, and compatible with other satellite navigation systems in the world. The Beidou satellite navigation system can not only provide high-precision and high-reliability positioning, navigation and timing services, but also has the characteristics of short message communication, differential service and integrity service. It is an indispensable major space for China's national security, economic and social development information infrastructure. The Beidou satellite navigation system broadcasts navigation signals in the L and S frequency bands, and launches open and authorized service signals on the three frequency points of the L frequency band...
