Example Embodiment

[0018] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0019] figure 1 It is a structural diagram showing the overall structure of a satellite communication terminal based on an SDR platform according to an embodiment of the present invention.

[0020] Such as figure 1 As shown in the figure, the satellite communication terminal of the present invention is mainly composed of an antenna 101, an SDR platform 102 and a PC 106 program. Among them, the main parameter requirement of the antenna 101 is a multi-band, multi-mode, and adjustable-gain satellite communication antenna, which is connected to the hardware equipment of the SDR platform 102 through an SMA interface. The hardware equipment of the SDR platform includes the radio frequency module 103, the bandwidth and frequency should match the antenna, the high-speed analog / digital ("A / D") and digital / analog ("D / A") module 104, and the high-performance on-site The program...

Description

technical field [0001] The present invention relates generally to the field of satellite communications. More specifically, the present invention relates to the design of satellite terminals based on a Software Defined Radio ("SDR") platform. Background technique [0002] For a long time, the complexity of satellite systems and the use of different frequency bands have made it difficult to achieve interconnection. With the wide application of wireless communication services in civil fields such as personal mobile communication and weather monitoring, the rapid development of wireless communication technology brings about continuous replacement of communication equipment, resulting in serious waste of resources. Satellite terminals are designed for a single satellite, function and purpose, and different satellite communication systems use different hardware platforms and architectures. Such repetitive hardware design leads to long development cycle and high cost of satellit...
