Answer it is specified go out channel.Network operation control centre according to it is current be that source ICBM SHF satellite terminal and the MEO of purpose ICBM SHF satellite terminal service are defended
Star information, completes the planning of star upper signal channel switching path, and feeds back star upper signal channelization to exchange configuration information to related MEO satellite.
Idiographic flow refers to as follows：Assuming that MEO satellite constellation is made up of 5 MEO satellites, adjacent MEO satellite has inter-satellite link, is source
The satellite of ICBM SHF satellite terminal service is the MEO5 in constellation, and the satellite for being the service of purpose ICBM SHF satellite terminal is the MEO2 in constellation.Such as Fig. 2
It is shown.
When source ICBM SHF satellite terminal has service needed to send to purpose ICBM SHF satellite terminal, network operation control centre according to MEO5 with
The annexation of MEO2, completes the planning of star upper signal channel switching path, i.e., enter channel 1 through MEO5 and exchange to MEO5 to go out channel 18,
Enter channel 18 through MEO1 and exchange to MEO1 to go out channel 18, enter channel 18 through MEO2 and exchange to MEO2 to go out channel 1.Such as Fig. 2 middle polylines
It is shown.
The above-mentioned star upper signal channelization of tri- satellites of MEO5, MEO1, MEO2 is exchanged configuration information by network operation control centre
It is respectively sent to respective satellite.Spaceborne channelizing exchanges payload reception to from after the signal for entering channel, can be configured according to exchanging
Information, being exchanged to going out channel, i.e. MEO5 accordingly will can receive from the signal for entering channel 1, exchange to going out channel
18, MEO1 will can be received from the signal for entering channel 18, exchange to channel 18 is gone out, and MEO2 can be come from what is received into letter
The signal in road 18, exchanges to going out channel 1.After the signal that source ICBM SHF satellite terminal sends is exchanged through above-mentioned star upper signal channelization, finally by mesh
ICBM SHF satellite terminal receive.
Another satellite communication method is provided in the present embodiment, MEO satellite is applied to, and Fig. 3 is according to of the invention real
Another flow chart of the satellite communication method of example is applied, as shown in figure 3, the flow comprises the following steps：
Step S301, star upper signal channel switching path is received from network operation control centre；
Step S302, the data is activation that will be received from source ICBM SHF satellite terminal according to the star upper signal channel switching path to this
The corresponding purpose ICBM SHF satellite terminal of source ICBM SHF satellite terminal.
By above-mentioned steps, network operation control centre is used to distribute star upper signal channel switching path for each MEO satellite,
Each MEO satellite is controlled to be transmitted to sending business datum by source ICBM SHF satellite terminal, until most business datum is transmitted to mesh at last
ICBM SHF satellite terminal, with moderate number of satellite, technical sophistication degree and communication performance.The side exchanged using digital channelizing on star
Formula, the satellite independence networking in same orbital plane is made using inter-satellite link, be only completed on star analog-to-digital conversion, digital channelizing and
Subchannel is exchanged, and on-board processing is relatively easy, reliability is high, to communication system strong adaptability, reduces satellite complexity, is reduced
The expense of earth station construction and maintenance and the resource occupied.
