While installing the aerial of Goldinfo wide ground
satellite station, need to adjust the azimuth, angle of elevation, polarize
the angle.
Azimuth: A orthographic projection line on the horizontal plane of the acceptance point of sight from acceptance point to satellite, to begin, the azimuth from clockwise direction to the angle, projection of line from straight the North of acceptance point. (This calculation with azimuthally database, has not considered magnetic declination, so should join local magnetic declination number value while using actually.) Angle of elevation: Contained angles that sight and level of looking up at the satellite from the acceptance point form are angles of elevation. Polarize the angle: The down signal of the satellite
transponder has two kinds of basic polarized directions: The level is
polarized and polarizes vertically. As to the earth different place,
polarize horn different, need polarization indicator polarization horn value
to get form to adjust RFU. |
