Ionosphere scintillation satellite signal simulation system and usage method thereof

Abstract

The invention relates to an ionosphere scintillation satellite signal simulation system and a usage method thereof, is suitable for BDS / GPS satellite signals, and aims to solve the ionosphere scintillation environment technical problems in the BDS / GPS satellite signal propagation process; the satellite signal simulation system is suitable for the BDS / GPS satellite signals, and comprises a hardwaredevice and a host computer connected through a series port; the host computer is configured with host computer software; the host computer software is used for forming a hardware device needed scenefile and configuration simulation parameters, and controlling and displaying the hardware device; the hardware device comprises a baseband signal module, a high stability crystal oscillator connectedwith the baseband signal module, a single-chip microcomputer module, a DA module and a power supply module; the DA module is also connected in order with a radio frequency module and an antenna; the antenna work frequency range covers the BDS / GPS satellite signal frequencies. The ionosphere scintillation satellite signal simulation system can well solve said problems, and can be applied to the satellite navigation positioning field.

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...
