The current antenna patterns illustrated angle of aerial array is still not necessary to adjustment, can now stop adjustment primary antenna and be adjusted with field pattern
Coupled relation between antenna, and after one section of preset time, then ab iitio satellite satellite-signal
Mean intensity, calculating threshold intensity, to continue to determine whether the angle adjustment that need to carry out antenna patterns illustrated, preset
Time may be, for example, 300 seconds, so be not limited.In addition, control unit 106 also can determine whether adjustment after it is each
Plant whether the corresponding mean intensity of antenna patterns illustrated is all less than the first preset strength, if the various antenna fields after adjustment
The corresponding mean intensity of type is all less than the first preset strength, can stop between adjustment primary antenna and field pattern adjustment antenna
Coupled relation, and after one section of preset time, be further continued for calculating the average strong of the satellite-signal of satellite
Degree, recalculates threshold intensity, and selects alternate satellite and target satellite again, to carry out antenna patterns illustrated
Angle adjustment.It can so avoid that in control unit 106 antenna patterns illustrated of correspondence target satellite can not be being adjusted out

Then choose the big satellites of alternate satellite Satellite signal intensity N, the intensity on the basis of its satellite signal strength
(step S612).Then whether judgment standard intensity is higher than threshold intensity (step S614), if reference intensity is high
In threshold intensity, selection alternate satellite Satellite signal intensity maximum is to satellite big N as target satellite
(step S616), namely the larger satellite of selection top n satellite signal strength, as target satellite, wherein N can
For example, 4, so it is not limited.After target satellite is selected, it just can enter step S502, calculate multiple
