Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in the technology of this area
Personnel are further appreciated by the present invention, but limit the present invention the most in any form.It should be pointed out that, the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, it is also possible to make some changes and improvements.These broadly fall into the present invention
Protection domain.
Satellite-borne data transmission antenna according to present invention offer is to ground force transfer system, including two be arranged on satellite
Independent number passes antenna, i.e. forward antenna and rearmounted antenna；Described forward antenna and rearmounted antenna are all able to receive that satellite sends
Instruction, it is achieved in halted state, switching between presetting angle state and tracking mode.
Adjacent earth station alternately followed the tracks of by described forward antenna and rearmounted antenna according to satellite command, to corresponding earth station
Transmitted data signal.
Specifically, as it is shown in figure 1, the satellite-borne data transmission antenna control method to ground force transfer system that provides of the present invention
Comprise the steps:
Aerial angle initialization step: the prepositioned instruction sent according to satellite, adjusts forward antenna and rearmounted antenna respectively
Angle；Wherein, described prepositioned instruction includes: preset target position angle, corresponding starting working the moment；Specifically, in regulation
Time in complete the angle of forward antenna and rearmounted antenna preset.
Forward antenna tracking step: when satellite is consistent with the angle of the angle of a certain earth station Yu forward antenna, satellite
Forward antenna is sent trace command, it is achieved the real-time tracking to this earth station, i.e. by forward antenna, this earth station is launched number
The number of it is believed that；
Rearmounted antenna tracking step: when satellite is consistent with the angle of the angle of next earth station Yu rearmounted antenna, satellite
Forward antenna sending halt instruction and sends trace command to rearmounted antenna, forward antenna stops following the tracks of, and rearmounted antenna realizes
Real-time tracking to this next earth station, i.e. by rearmounted antenna to this next earth station's transmitted data signal；
Instruction waiting step: when the angle of satellite Yu next earth station exceedes setting threshold value, send to rearmounted antenna and stop
Only instruction, then forward antenna, rearmounted antenna are in halted state, wait the prepositioned instruction of satellite.
Specifically, as in figure 2 it is shown, define two-dimentional machinery scanning element beam antenna A (aft antenna), two-dimentional machinery scanning element ripple
Beam antenna B (front antenna), grounded receiving station 1 (next stop), grounded receiving station 2 (station afterwards).Work process includes: step 1, and antenna is quiet
Only；Step 2, preset；Step 3, A antenna tracking transmits；Step 4, A antenna switches to B antenna；Step 5, B antenna tracking transmits；
Step 6, stops.
Step 1: antenna A, antenna B remain static, for the halted state of front one action process, now satellite is the most right
Antenna A, antenna B send instruction, and the most described state is that satellite-borne data transmission antenna is awaited orders duty.
Step 2: arrange antenna A, the preset condition of antenna B, number passes antenna and opens, then antenna A, antenna B receive pre-simultaneously
Putting instruction, described prepositioned instruction includes: preset target position angle, corresponding starting working the moment, according to preset target angle
Position, antenna current angle position be poor and the constraint such as preset angular velocity, and antenna A, antenna B complete angle the most at the appointed time
Preset.Specifically, reference satellite heading, aft antenna (A antenna) points to pre-finger, front antenna (B to first passing through earth station
Antenna) to after carry out angle through earth station and refer in advance.
Step 3: make A antenna be in tracking transmission state, in satellite this task process in orbit, when satellite and ground
When station, face 1 angle is consistent with A antenna presetting angle, A antenna receives the trace command that satellite sends, it is achieved (front to earth station 1
Stand) real-time tracking, carry out the transmitting of data signal simultaneously.
Step 4: in satellite this task process in orbit, when satellite and earth station 2 angle and B antenna presetting angle one
During cause, A antenna receives the halt instruction that satellite sends, and i.e. stops the real-time tracking to earth station 1 (next stop), stops data simultaneously
The transmitting of signal；B antenna receives the trace command that satellite sends, it is achieved the real-time tracking to earth station 2 (station afterwards)；Meanwhile, defend
Data signal path switching is delivered to B antenna by star, and B antenna proceeds by the transmitting of data signal.
Step 5: make B antenna tracking transmission state, satellite possesses and carries out data transmission segmental arc bar with earth station 2 (station afterwards)
Part, B antenna transfers to from the sensing resting state of presetting angle and dynamically points to tracking mode, carries out the transmitting of data signal simultaneously；
Now, earth station 2 (next stop) receives data signal；
Step 6: when satellite flies away from earth station 2 (station afterwards), B antenna stop to earth station 2 (station afterwards) dynamically point to
Track, stops the transmitting of data signal simultaneously；A, B antenna all quits work, and number passes antenna and is in off-position, waits next number of times
The beginning of the number of it is believed that transformation task.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make a variety of changes within the scope of the claims or revise, this not shadow
Ring the flesh and blood of the present invention.In the case of not conflicting, the feature in embodiments herein and embodiment can any phase
Combination mutually.
