The difference between the design and the satellite communication antenna is that the way of adjusting the course angle and the pitch angle through the transmission mechanism 102 is changed, so that the precision is higher and the capability of resisting external force is stronger. However, the same points of two different structures of satellite antennas are: there is a part of the components that are stationary and a part of the antenna structure is adjusted to the star, the stationary component being the lower support 100 for the first configuration and the bottom rail base 200 for the new configuration.

Example 1
In order to better understand the structure of a self-propelled portable satellite communication antenna according to the present invention, the following specific description is made with reference to fig. 3 to 5:
the invention relates to a self-propelled portable satellite communication antenna, which comprises a driving component 2, a supporting component 3 and an antenna communication component 4. The supporting component 3 has the function of adjusting the pitching angle, and the driving wheel 22 in the driving component 2 is directly in rotary contact with the ground and is used for providing power for horizontally rotating the satellite communication antenna to adjust the course angle. Meanwhile, the support assembly 3 is located at the bottom of the antenna communication assembly 4, and the driving assembly 2 is located at the bottom of the support assembly 3.
It should be noted that: the ground is a carrier for carrying the satellite communication antenna, and can also be a carrier such as a packing box, a board and the like, and is not limited to the above.
In this embodiment, in order to improve the stability and balance of the structure, the driving assemblies 2 are arranged in three groups, specifically, the number of driving assemblies can be increased according to the actual requirement, specifically, four groups, five groups or more driving assemblies are also included in the scope of the present invention, but three groups are enough to complete the stable support and driving relative to the present embodiment, and the structure is also the simplest, and the cost is the lowest correspondingly. After three groups of driving assemblies 2 are arranged, namely each group of driving assemblies 2 is independently driven, so that the overall stability is improved.
Meanwhile, the side part of the antenna communication component 4 is provided with a measuring component 1 which can collect the course angle of the antenna communication component in real time when rotating, thereby providing basis for adjusting the course angle. The invention also comprises an inclination angle sensor (not shown in the figure) and a calculator (not shown in the figure), wherein the inclination angle sensor can acquire the pitching angle of the antenna communication assembly in real time when rotating, so that basis is provided for adjusting the pitching angle, the measuring assembly 1 and the inclination angle sensor send corresponding angle information to the calculator, and the calculator calculates the course angle to be adjusted and the pitching angle to be adjusted.

Specifically, the measuring assembly 1 comprises a supporting rod 11, a positioning rod 12, a first measuring antenna 13 and a second measuring antenna 14, wherein the supporting rod 11 is positioned at the bottom of the antenna communication assembly and is used for supporting the positioning rod 12; the positioning rod 12 is clamped with the supporting rod 11, the first measuring antenna 13 and the second measuring antenna 14 are respectively located at two sides of the positioning rod 12, and the calculator is in wireless connection with the first measuring antenna and the second measuring antenna and is used for calculating an angle to be adjusted according to the course angle measured by the first measuring antenna 13 and the second measuring antenna 14. The first measuring antenna 13 and the second measuring antenna 14 are distributed on two sides of the positioning rod 12 with the middle point of the positioning rod 12 as a symmetrical center, and are not limited to be distributed on other positions. The positioning rod 12 is parallel to the horizontal plane, so that the subsequent calculation is simpler and quicker.

The first measurement antenna 13 and the second measurement antenna 14 are GNSS measurement antennas, and include various satellite navigation systems, such as a GPS navigation positioning system, a BDS beidou satellite navigation system, a GLONASS satellite navigation system, and the like. For the above course angles obtained by the first measurement antenna 13 and the second measurement antenna 14 to calculate the angle to be adjusted, the conventional algorithm is utilized, and will not be described herein.
In the positioning process, firstly, signals in the horizontal direction are searched, and then signals in the pitching direction are searched, namely, the course angle is firstly adjusted, and then the pitch angle is adjusted. The purpose of this arrangement is that: the problem that the pitch direction is searched again because the wheel encounters the uneven ground when rotating in the horizontal direction is avoided by searching the pitch direction signal.

In order to enhance the stability of the turnover support rod 33, a bar 35 is disposed on a side wall thereof, and the other end of the bar 35 is fixed to the upper surface of the driving hub 32.
The number of the horizontal support rods 31 is determined according to the number of the specific driving components 2, in this embodiment, three groups of driving components 2 are adopted, and then three horizontal support rods 31 are correspondingly arranged and fixed on the driving center 32. The driving center 32 is used as a control center of the whole equipment, and is used for controlling the motor 23 in the driving assembly 2 to rotate by a corresponding angle according to the course angle to be adjusted and the pitch angle to be adjusted calculated by the calculator, controlling the pitch push rod 34 to slide by a corresponding distance, and completing adjustment of the course angle and the pitch angle.
During the process of enabling the antenna communication assembly 4 to complete rotation as a whole to achieve heading angle adjustment, all the driving wheels 22 can rotate together at the same time; it is also possible to complete the rotation of the other driving wheels 22 around one of the driving wheels 22. Thus, the power provided by the motor 23 may also be different.
The overturning supporting rod 33 is used for matching with the pitching pushing rod 34 to complete adjustment of the pitching angle of the antenna communication assembly, wherein when the pitching pushing rod 34 is driven by the driving hub 32 to move upwards or downwards, the pitching angle of the antenna communication assembly 1 is correspondingly adjusted, and accordingly satellite-based operation is completed.
In order to further enhance the fixability of the flip support rod 33, a latch 35 is provided at the driving hub 32, one end of which is fixed to the flip support rod 33 and the other end of which is fixed to the driving hub 32.

step S2, detecting a real-time pitch angle of the satellite communication antenna by using a pitch angle sensor, and calculating a pitch angle difference between the real-time pitch angle and a theoretical pitch angle by using a calculator; according to the pitching angle difference, the supporting component drives the antenna communication component to rotate in the vertical direction to adjust the pitching angle, so that the satellite communication antenna points to the theoretical pitching angle;
step S3: and fine-tuning the course angle and the pitch angle to enable the satellite communication antenna to point to the azimuth with the strongest signal.
