With 2 signal output ports；The multi-mode modulator includes 1 digital sum of fundamental frequencies module, and 1 switchs, 2 tunnel modulation channels, often
Road modulation channels contain 2 signal input ports and 1 signal output port；The spaceborne ip router includes 4 input terminals
Mouth and 4 output ports；The switch of the multi-mode demodulator has 2 kinds of operating modes, independent beam operating mode and multiplex
Beam operating mode, independent beam operating mode are the input terminals of the input port and multi-mode demodulator in switching gate demodulation channel
Mouthful, multiplex beam operating mode is the output port of the input port and digital frequency division module in switching gate demodulation channel, described more
The switch of mode modulator has 2 kinds of operating modes, independent beam operating mode and multiplex beam operating mode, independent beam work
Pattern is the output port of switching gate modulation channels and the output port of multi-mode modulator, and multiplex beam operating mode is switch
Gate the input port of the output port and digital sum of fundamental frequencies module of modulation channels；The uplink frequency-variable module or No. 2 satellites of No. 1 satellite
Uplink mixing bridge output signal respectively enter multi-mode demodulator 12 input ports and 2 of multi-mode demodulator 2
Input port, into 2 road signals of multi-mode demodulator 1, the i.e. roads a1 and the roads b1, the wherein roads a1 directly can enter solution by switching
Adjust channel 1；The roads b1 can by being divided into 2 tunnels, the i.e. roads a11 and the roads b11 after digital frequency division module, wherein the roads a11 can by switch into
Entering to demodulate channel 1, the roads b11 are directly entered demodulation channel 2, into 2 road signals of multi-mode demodulator 2, the i.e. roads a2 and the roads b2,
The middle roads a2 directly enter demodulation channel 3 by switching；B2 by being divided into 2 tunnels, the i.e. roads a21 and the roads b21 after digital frequency division module,
The middle roads a21 enter demodulation channel 3 by switching, and the roads b21 are directly entered demodulation channel 4, after signal is demodulated and respective handling,
The 1st tunnel output signal for demodulating channel 1 enters the 1st input port of spaceborne ip router A, the 2nd tunnel output in demodulation channel 1
Signal enters the 1st input port of spaceborne ip router B, and the 1st tunnel output signal in demodulation channel 2 enters spaceborne ip router
2nd tunnel output signal of the 2nd input port of A, demodulation channel 2 enters the 2nd input port of spaceborne ip router B, solution
The 1st tunnel output signal in channel 3 is adjusted to enter the 3rd input port of spaceborne ip router A, the 2nd tunnel output letter in demodulation channel 3
1st tunnel output signal of the 3rd input port of number spaceborne ip router B of entrance, demodulation channel 4 enters spaceborne ip router A
The 4th input port, demodulation channel 4 the 2nd tunnel output signal enter spaceborne ip router B the 4th input port, signal
After the signal processing of spaceborne ip router and route switching, the 1st road of spaceborne ip router A and spaceborne ip router B are defeated
Go out the modulation channels 1 that signal enters multi-mode modulator 1, the 2nd tunnel output letter of spaceborne ip router A and spaceborne ip router B
Number enter the modulation channels 2 of multi-mode modulator 1, the 3rd tunnel output signal of spaceborne ip router A and spaceborne ip router B into
Enter the modulation channels 3 of multi-mode modulator 2, the 4th tunnel output signal entrance of spaceborne ip router A and spaceborne ip router B are more
The modulation channels 4 of mode modulator 2, signal after ovennodulation and respective handling, believe by the output of modulation channels 1 and modulation channels 3
It number can be directly by switching output to the downlink frequency conversion amplification module of No. 1 satellite or the down mixing bridge of No. 2 satellites, or pass through
Output is to the downlink frequency conversion amplification module of No. 1 satellite or the down mixing bridge of No. 2 satellites after digital sum of fundamental frequencies module；Modulation channels 2
It is defended with the output signals of modulation channels 4 by being exported after digital sum of fundamental frequencies module to the downlink frequency conversion amplification module of No. 1 satellite or No. 2
The down mixing bridge of star.
