[0002] Satellite communication is the communication between radio communication stations on the earth using satellites as relays. Satellite communication has the characteristics of large coverage area, long communication distance, flexibility, stable and reliable lines, and no geographical restrictions. It has been increasingly valued in the process of communication development. Its application in exploration, mining, fishing, agriculture, animal husbandry, logistics and other industries has gradually increased.

[0003] In recent years, with the rapid development of small satellite technology, the continuous reduction of commercial space costs, and the increasing demand for satellite Internet access anytime and anywhere, low-orbit satellites have gradually become the mainstream choice for satellite Internet construction with their advantages of low latency, low cost, large system communication capacity, and redundant networking. As a result, the corresponding satellite communication equipment has also begun to develop rapidly, and the market development prospects are broad.

[0004] The satellite communication terminals currently on the market usually only have single-orbit satellite communication functions, and their functions are relatively simple, and they are not compatible with satellite communication systems in other orbits. For example, conventional low-orbit satellite communication terminals such as the United States' Swarm, Iridium, and China's Apocalypse constellation can only support low-orbit satellite communication systems; conventional high-orbit satellite communication terminals such as China's Beidou and Tiantong can only support high-orbit satellite communication systems. Satellite communication terminals that support multiple orbits at the same time can only be made individually according to customization, with a long R&D cycle and high costs. Utility Model Content

The cover 12 is sleeved outside the retaining edge 114 and the cover 12 and the retaining edge 114 are detachably fixedly connected. The fixed connection can be a threaded fastening connection, a snap connection, a riveting connection, etc. A cavity 13 is formed between the base 11 and the cover 12, and the satellite communication antenna and the hardware mainboard 16 are arranged in the cavity 13. A bracket 116 can also be arranged at the center of the lower end of the base 11. The bracket 116 can be used to install the satellite communication terminal 10 or support it. In this embodiment, the base 11 is a circular structure, and the cover body 12 is a hemispherical structure, but the present invention is not limited thereto.

[0030] The antenna module 14 includes a satellite communication antenna 141 and a navigation positioning antenna 146. The satellite communication antenna 141 and the navigation positioning antenna 146 are disposed in the cavity 13 and connected to the base 11.

[0031] The satellite communication antenna 141 includes a low-orbit satellite communication antenna 142, a medium-low-orbit satellite communication antenna (not shown), and a high-orbit satellite communication antenna 144. The satellite communication antenna 141 and the satellite communication module 164 are specifically low-orbit, medium-low-orbit, and high-orbit satellite communication modules. In this embodiment, the high-orbit satellite communication antenna 144 is a Beidou high-orbit satellite communication antenna, and the navigation positioning antenna 146 is a high-precision positioning navigation antenna. The low-orbit satellite communication antenna 142, the high-orbit satellite communication antenna 144, and the navigation positioning antenna 146 are connected to the fixed column 112 of the base 11 through the mounting bracket 148. Specifically, the mounting bracket 148 is at least a double-layer bracket and the upper and lower layers are arranged at intervals. The lower end of the mounting bracket 148 abuts against the fixed column 112 and is detachably fixedly connected to the fixed column 112.

The high-orbit satellite communication antenna 144 and the navigation and positioning antenna 146 are respectively fixed to the upper layer of the mounting bracket 148. The high-orbit satellite communication antenna 144 (navigation and positioning antenna 146) and the low-orbit satellite communication antenna 142 are separated by a certain distance and do not interfere with each other.

[0032] The antenna module 14 is combined into an antenna module 14 according to different satellite communications and different positioning functions, and is simultaneously arranged in the cavity 13.
