Abstract

The invention discloses a multi-mode multi-aperture multi-band backpack satellite station, which comprises a satellite antenna, an integrated radio frequency assembly and a platform, and is characterized in that the integrated radio frequency assembly comprises an up-conversion power amplifier BUC and a low-noise down-conversion amplifier LNB; the platform comprises a modem, a multimode detection module, a clinometer, a GPS, an antenna controller, an antenna servo and a polarization sensor, wherein the multimode detection module comprises a power divider, a DC blocking module, a power supply module, a control module, an intermediate frequency receiving and processing module and a clock; switching is simple, switching time is short, and frequency band switching can be supported without tools; the universality is high, and a unified platform supports feed sources with different calibers and different frequency bands; the localization rate is 100%, the cost performance is high, the platform sharing rate of two frequency band devices can reach 92%, and the device cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of satellite antennas, in particular to a multi-mode, multi-aperture and multi-band piggyback satellite station. Background technique [0002] With the development of satellite communication technology, satellite communication has begun to enter the civilian market, which has higher requirements for satellite antennas. Since satellite communication is greatly affected by environmental changes, the differences in satellite communication in different frequency bands are more obvious, such as: ka bandwidth is wide, but It is greatly affected by rain attenuation; C-band antennas are less affected by rain attenuation, but have higher requirements on the antenna aperture; in addition, the new medium and low orbit satellites belong to different frequency bands, and the satellite stations are required to meet overhead tracking. At present, the traditional single-frequency, single-caliber piggyback satellite station will be di...
