However, existing high-throughput satellite communication terminal products cannot simultaneously meet the comprehensive needs of "flexible and lightweight, high-speed bandwidth and real-time communication" in single-person mobile scenarios, and there is a significant product gap in the market.

[0003] Current technologies all employ integrated designs for flat panel antennas, BUCs, LNBs, inertial navigation systems, and other components, using foldable, height-adjustable brackets and backpacks to store batteries. However, these products have several drawbacks: they lack a technologically advanced and brand-recognizable appearance, and the main body of the device is bulky; unfolding and folding require multiple steps, battery replacement is cumbersome, and the user experience is poor; the ergonomic design of the carrying system is inadequate, with a high and rearward center of gravity, unstable connections, and severe shaking during movement, making it difficult to carry for extended periods; and the functional integration is low, only meeting basic satellite communication needs, while video transmission, data security, and voice calls require additional equipment. Existing products have shortcomings in terms of ease of operation, carrying experience, and functional integration, and cannot meet the diverse needs of scenarios such as inspection and emergency rescue.

6. The backpack mobile communication terminal system according to claim 5, characterized in that, The radio frequency related components are used for: In the transmission link, the data to be transmitted is encoded by the Modem, and then the BUC converts and amplifies the low-frequency encoded signal into a transmission signal. The polarizer calibrates the polarization direction of the signal to match the satellite link, and finally the signal is directionally transmitted to the satellite through the low-profile small-diameter flat panel antenna. In the receiving link, the low-profile small-aperture flat panel antenna captures the satellite signal transmitted by the satellite. After the polarizer completes the signal polarization direction matching, the LNB converts the high-frequency satellite signal into a low-frequency signal and filters out interference noise.
