Background technique

Traditional portable satellite stations use manual star-finding devices or automatic star-finding methods. In order to achieve rapid star positioning of equipment, most of them use GPS/BD positioning and inclination sensors to assist star alignment. However, the traditional method adopts the method that GPS/BD positioning is separated from the tilt sensor, and the tilt sensor is fixedly installed. As described in CN109031370A, the manual antenna uses a hand-held terminal to assist in the star-seeking process. The hand-held terminal includes a positioning component, a processor, a compass, a level, an input and output component and a communication component, which are installed on the feed arm, and the satellite transceiver component. Fixed installation, which is a waste of space and low integration.

In addition, because the mechanism does not have the characteristics of control, the operation is more complicated. General communication equipment needs to start the power of the device, then click the expand/collect button to expand the device, then manually flip the transceiver assembly, install the antenna side lobe, and finally press the expand/collection button again to start automatic star alignment. This method increases the complexity of human operation and increases the time for satellite alignment. If the transceiver components are not turned over, they can be stored directly, resulting in damage to the equipment.

Application number CN201922434536.5 A smart satellite terminal transceiver assembly flipping mechanism, the mechanism includes a transceiver assembly module, a positioning and navigation sensor, a transceiver assembly bracket, a rotating shaft, a positioning pin and a transceiver assembly arm. The transceiver assembly module and positioning It is fixed on the transceiver assembly bracket together with the navigation sensor. The transceiver assembly bracket is rotatably connected to the transceiver assembly arm through the rotating shaft. The transceiver assembly arm is provided with a positioning hole, and the transceiver assembly arm passes through the positioning hole and the corresponding positioning pin. Locate and secure the transceiver module. The utility model can automatically align the stars and automatically collect, and can accurately perceive the target position state, realize one-key unfolding and collection while reducing the volume of the equipment, avoid the damage caused by the direct collection of the unturned components, and avoid the position error in the working process. It reduces the repair and maintenance costs brought by the split type, reduces the number of components, improves the degree of system integration, reduces the volume and weight of the equipment, and is convenient for customers to use, but it also has the following disadvantages:

In the process of adjusting the angle between the transceiver component bracket and the transceiver component arm, because there is no specific fixing device, it is difficult to adjust the more accurate position, the operation is difficult to control, and it may be rotated at a large angle, which is more troublesome, and there is no fixed structure before the pin is installed. , There is still the problem of angle change when the pin is installed, the installation is more inconvenient and the accuracy is poor.
