A satellite signal simulation system for ionospheric scintillation and its application method

Abstract

The invention relates to a satellite signal simulation system for ionospheric scintillation and its use method, which is suitable for BDS / GPD satellite signals and solves the technology that cannot reproduce the ionospheric scintillation experienced in the propagation process of BDS / GPS satellite signals The problem is that the satellite signal simulation system is suitable for BDS / GPD satellite signals, including a hardware device connected through a serial port and a host computer. The host computer is configured with host computer software, and the host computer software is used to generate scene files required by the hardware device, Configure analog parameters and control and display hardware devices; the hardware devices include a baseband signal module, a high-stable crystal oscillator connected to the baseband signal module, a single-chip microcomputer module, a DA module and a power supply module, and the DA module is also connected with a radio frequency module and an antenna in turn, and the antenna works The technical scheme of frequency band covering BDS / GPS satellite signal frequency solves this problem better and can be used in satellite navigation and positioning.

Description

technical field [0001] The invention relates to the field of navigation and positioning, in particular to an ionospheric scintillation satellite signal simulation system and a using method. Background technique [0002] With the continuous development and maturity of satellite navigation technology, the wide application of satellite navigation system has played a huge role in promoting national economic and social development, and in recent years, in precision agriculture, scientific research (field biology, meteorology, earth Science), environmental monitoring, emergency and disaster assessment, safety assurance, celestial and architectural engineering, and natural resource analysis have been increasingly used. At present, the mainstream satellite navigation systems in the world include GPS of the United States, GLONASS of Russia, Beidou of China and Galileo of Europe. GPS is the world's first mature satellite navigation system, which has omnipotent, global, all-weather co...
