Emergent occasion, ambient enviroment is complex, and application site is not fixed, and satellite resource is not fixed, therefore is proposed to searching star process
Higher technology requirement.It analyzes existing commercial communication in moving and searches star scheme, be basically divided into following two：
The first, carrier absolute geographical coordinate and orientation is obtained mainly by the GPS connected firmly with carrier, after booting, so
Afterwards according to target satellite parameter directly by near the pitch angle of antenna and azimuthal movement to target angle, then pass through acquisition beacon
It realizes to star.This method needs to use differential GPS, or waits for carrier movement that could be obtained later when place by single GPS
Parallactic angle, although higher to star accuracy, search the star time provides time of information depending on GPS, often up to a few minutes as long as,
This will largely effect on the use of contingency procedure.
It second, carries out searching star by Radio Beacon and to star thresholding, this is also the scheme of most of miniaturized systems.Pass through
For communication equipment according to the beacon level intensities of different satellites, manual setting is different to star thresholding.Make after booting antenna movement to pair
Then star pitch angle starts orientation blind sweep at a slow speed, after beacon level reaches setting value, stop azimuth axis movement, completion pair
Star.This method is simple, is easily achieved, but disadvantage also has very much, and first, it needs to debug manually in advance and set more of typing to defend
The beacon level of star, and beacon level can also slightly have difference with the difference of place to use, this gives prodigious using above bringing
Trouble；Second, fixed level threshold so that anti-interference is poor, once there are other reflectings surface or signal source (ratio around antenna
As there are multiple portable stations in emergency communication place), beacon level can be caused to obscure, so as to cause the generation accidentally to star phenomenon.

Description of the drawings
Fig. 1 is the work flow diagram of the present invention.
Specific implementation mode
Below in conjunction with the accompanying drawings, the present invention is described in detail.
As shown in Figure 1, the present invention provides a kind of adaptive anti-interferences for mobile satellite communication system to star method, tool
Body includes the following steps：
Step 1：After mobile satellite communication system is started to work, the pitch axis for controlling antenna does pitching movement until top limits
Antenna surface is realized towards sky in position, then controls the azimuth axis rotation of antenna, the automatic gain during acquisition azimuth axis rotation
The average voltage for controlling voltage is made an uproar voltage the bottom of as.Wherein, mobile satellite communication system is a three axis communication in moving, the fortune of antenna
It is dynamic that comprising three orientation, pitching, polarization axis, isolation carrier movement is realized in the movement by controlling these three axis, the moment keep with
The wave beam of track satellite connects firmly azimuth, pitch angle and polarizing angle that an AHRS module measures antenna in real time on antenna surface.When
When system starts, the pitch axis of antenna can do pitching movement, and a limit switch can be touched when pitch axis is to top, is made
Antenna surface is towards sky.Control antenna azimuth axis rotate generally within 10 seconds can, azimuth axis rotates on one side, one
Side acquires AGC voltages.
Step 2：According to the longitude of target satellite, polarization mode and current geographic information, calculates to star polarizing angle and bow
The elevation angle.Wherein current geographic information can be that system GPS or the Big Dipper provide.
Step 3：Start the polarization motor in mobile satellite communication system, makes antenna movement to the polarizing angle calculated；It opens
Dynamic pitching motor makes the pitch angle calculated in antenna movement to step 2, and refers to mould using the navigation attitude connected firmly with antenna surface
The tracking that the Eulerian angles of block output carry out pitch angle is kept.
Step 4：Start the azimuth-drive motor in mobile satellite communication system, according to the azimuth axis of inceptive direction rotary antenna,
One circle of scanning, acquires and records the maximum value MAX_AGC of the AGC voltage in a circle.
Step 5：The azimuth axis that mobile satellite communication system controls antenna rotates simultaneously according to the direction opposite with inceptive direction
One circle of scanning, acquires and records the AGC voltage in a circle, when collecting AGC voltage and step 4
In collected AGC voltage maximum value MAX_AGC be close and repeatedly confirm after, then record orientation at this time
Angle is azimuth A when first time maximum value occurs1。
Step 6：Mobile satellite communication system controls the azimuth axis of antenna according to opposite with the azimuth axis direction of motion in step 5
Direction rotate and scan a circle, the AGC voltage in a circle is acquired and records, when collecting automatic gain control
After voltage processed is close with the maximum value MAX_AGC of collected AGC voltage in step 4 and confirms repeatedly, then remember
The azimuth of record at this time is azimuth A when second of maximum value occurs2。
Wherein, since the maximum value MAX_AGC of AGC voltages can have gently with the power of satellite beacon, weather heat dispersal situations
Be slightly variable it is dynamic, so in step 5 and step 6 in collected AGC voltages and step 4 collected AGC voltages maximum value
MAX_AGC is confirmed repeatedly when difference is less than 1.5dB；When continuous acquisition to current AGC voltages>(MAX_AGC-1.5dB) surpass
It crosses after 5 times, then confirms success, then record azimuth at this time.
Step 7：Judge | A1-A2| value, if | A1-A2|<B, then it is assumed that star success, A is taken as to star angle1And A2In
Point, system opening searches star program, and to enter tracking servo-actuated；If B<|A1-A2|<2B then takes new A1=(A1+A2)/2, then proceed to
Step 6, and the number of turns of writing scan are carried out, if the reciprocal number of turns is more than maximum set value, re-starts the scanning of step 4；Such as
Fruit | A1-A2|>2B, then re-start the scanning of step 4, and wherein B indicates Eulerian angles error range, and Eulerian angles are missed in the present embodiment
Poor range B is 6~10 degree, and Eulerian angles error range B depends on antenna beamwidth, the drift velocity of AHRS modules, dynamic essence
Degree.Different antennas, different AHRS need that different numerical value is arranged.Antenna beam is wider, AHRS drift velocities are bigger, dynamic
State precision is lower, then the setting of B is bigger.The maximum set value of the reciprocal number of turns is 5.
Existing communication in moving existing on the market will be all arranged according to satellite to be fixed to star thresholding, this makes debugging process
It is relatively complicated.Since surrounding has multiple portable stations, the reflection of multiple big antenna surfaces, there are many reflected beam direction, and it is often right to cause
Star mistake, to the satellite-signal reflected back, AGC voltages are also very high, and can not normal communication, using side provided by the invention
Just without there is accidentally the phenomenon that star after method.The speed of star is also effectively raised.
