When stored, the primary rod 2a, the servo assembly 3 and the Ku-band antenna assembly 1 are folded into one body, and the secondary rod 2b is stored separately. When in use, the primary rod 2a, the servo assembly 3 and the Ku-band antenna assembly 1 are first taken out, and then the secondary rod 2b is assembled with the primary rod 2a to achieve rapid assembly. When the portable station power is turned on, the portable station can perform automatic alignment. The alignment process controls the servo assembly 3 to adjust the polarization, azimuth and pitch directions through the built-in control system, and adjusts according to the actual situation of the alignment, and finally completes the automatic alignment of the portable station. In terms of the time used for alignment, depending on the terrain, the alignment process can generally be completed in about two to three minutes.

[0042] like Figure 3 and Figure 4 As shown, the servo assembly 3 includes a connecting plate 3a, a polarization servo 3b, a sector gear 3d, an inner liner 3e, a sleeve 3f, a first bevel gear 3g, a first servo 3h and a second servo 3i. In this embodiment, the polarization servo 3b provides a driving force for rotation in the polarization direction, and the first servo 3h and the second servo 3i can provide a driving force for rotation in the azimuth and pitch directions under different working conditions.

[0043] The fixed part of the connecting plate 3a is fixedly connected to the center position of the back side of the shell of the Ku-band antenna assembly 1.

[0044] like Fig.10 , Fig.11 and Fig.12As shown, the first bevel gear 3g is coaxially fixed on the top of the primary rod 2a, the inner liner 3e is fixedly connected to the inner wall of the first bevel gear 3g, the inner liner 3e is coaxial with the primary rod 2a, the sleeve 3f is sleeved on the outside of the inner liner 3e, the sleeve 3f can rotate relative to the inner liner 3e, the first steering gear 3h and the second steering gear 3i are symmetrically installed on the rotating part of the connecting plate 3a, the second bevel gear 3j is installed on the output shaft of the first steering gear 3h, and the third bevel gear 3k is installed on the output shaft of the second steering gear 3i, the second bevel gear 3j and the third bevel gear 3k are respectively rotatably connected to the two sides of the sleeve 3f, and are respectively meshed with the first bevel gear 3g; when performing azimuth rotation During movement, the first steering gear 3h and the second steering gear 3i rotate in the same direction.
