Abstract

The invention discloses portable satellite navigation regional service quality comprehensive evaluation equipment, and belongs to the technical field of satellite navigation. The system comprises an integrated monitoring antenna, a satellite navigation monitoring receiving unit, an interference monitoring receiving unit, a monitoring and data processing unit, a time frequency unit, a power supply distribution module and a battery. According to the invention, a combined and miniaturized design is adopted, and a satellite navigation interference monitoring function and a navigation signal monitoring function are integrated, so that the equipment can realize real-time detection and direction-finding positioning of interference in a satellite navigation frequency band and availability monitoring of each frequency point signal of satellite navigation; and the service quality of the satellite navigation system in the region is comprehensively evaluated according to the results of interference monitoring and integrity monitoring. According to the invention, comprehensive evaluation of the availability of the satellite navigation system in a certain area can be realized.

Description

technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a portable satellite navigation area service quality comprehensive evaluation device. Background technique [0002] At present, there is no integrated design equipment for navigation signal availability monitoring and interference monitoring in China. Similar equipment only has separate interference monitoring equipment or satellite navigation integrity monitoring receivers, and does not have the ability to comprehensively evaluate the regional availability of satellite navigation systems. There is no integrated integration. According to the application characteristics of the satellite navigation field, the interference monitoring in the frequency band of the satellite navigation system and the integrity assessment of the satellite signal are combined to complete regional service quality monitoring, interference detection, interference orientation and positioning, and...
