Described data storage circuitry 29-3 be mainly used in storing the emergency satellite communication sky watch system to the parameter of satellite, comprise the beacon frequency of satellite, polarization of the e mode, satellite positioning longitude etc.A general cover mobile satellite communication earth station is only for a communication satellite job, so this data storage circuitry 3 can for a long time with the station use, if star work need to be changed in this station, can be restored to the parameter modification in the data memory circuit 3.
Operation principle of the present invention and the course of work are: after carrying case transports the scene to, open case lid 4, launch button 29-11 output antenna by operation PC monitoring equipment 27, PDA human-computer interaction device 28 or antenna and launch control signal, the main lobe 19-1 that controls six distinguish carbon fiber antenna main reflectors 19 launches each secondary lobe of assembly unit; By operation PC monitoring equipment 27, PDA human-computer interaction device 28 or automatic star-seeking button 29-12 output automatic star-seeking control signal, main controller module 26-1 is according to beacon receiver 26-4, the data that GPS module 26-7 and electronic compass 26-8 collect, under the horizontal system of coordinates during computing to the orientation of star, pitching, the polar theory angle, and according to orientation angles transducer 26-5, the data that luffing angle transducer 26-10 and polarization angular transducer 26-6 collect, computing is to the driving desired value of star and by the azimuth-drive motor in the drive amplification circuit module 26-9 driving direction drive 24, polarization motor rotation among pitching motor in the pitch drive 25 and the polarization power drive mechanism 23-4, so that antenna runs to star point of theory position, after antenna arrives theoretical position, main controller module 26-1 is according to satellite-signal characteristic and antenna beam characteristic, driven antenna automatic search satellite, and automatic tracking satellite keeps communications status; During communication, satellite-signal at first enters six distinguish carbon fiber antenna main reflectors 19, reflex to antenna subreflector 21 from six distinguish carbon fiber antenna main reflectors 19 again, antenna subreflector 21 reflexes to satellite-signal the feed assembly again and enters satellite signal receiving system, the ground transmitter signal, mails to satellite and carries out the bidirectional information communication again to six distinguish carbon fiber antenna main reflectors 19 from the feed assembly to antenna subreflector 21.Owing to adopted secondary reflection (rear feed type), so that feed assembly bracing frame 20 shortens, reduced the length of collection with carrying case.Behind the end-of-job, pull down each secondary lobe from main lobe 19-1, by operation PC monitoring equipment 27, PDA human-computer interaction device 28 or antenna collection button 29-13, main controller module 26-1 control antenna is finished automatic collection, folding storage is under casing 1, then be contained in each secondary lobe in the sack and be placed on the main lobe 19-1, cover case lid 4, form carrier state as shown in Figure 6, overall weight is 27Kg, volume 600 * 540 * 390mm3, the single carrying, movable pulley 9 has been installed in the bottom of under casing 1, is convenient to pulling.
In sum, the present invention has increased communication bandwidth, has realized that a kind of emergency satellite communication sky portable, automation mechanized operation watches system, be used for accident emergency disposal process, the single scene that transports to, satellite communication link between the Rapid Establishment two places is for emergency disposal provides communication support.
The above; it only is preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection range of technical solution of the present invention.
