Difference positioning testing method and device for satellite-navigation ground-based augmentation system

Abstract

The invention provides a difference positioning testing method and device for a satellite-navigation ground-based augmentation system.The pseudo-range difference testing function and the phase difference testing function are integrated, and meanwhile the positioning resolving results of the pseudo-range difference and the phase difference are output; the provided device is quite convenient to carry, install and use.The device comprises a central processor module, a satellite-navigation difference positioning module, a mobile communication module and a multimedia broadcasting module.The central processor module is respectively connected with the satellite-navigation difference positioning module, the mobile communication module and the multimedia broadcasting module, and used for receiving mobile communication difference data obtained by the mobile communication module or multimedia broadcasting difference data obtained by the multimedia broadcasting module, receiving satellite navigation difference data output by the satellite-navigation difference positioning module, carrying out difference positioning resolving on the mobile communication difference data or the multimedia broadcasting difference data and the received satellite navigation difference data and meanwhile outputting the positioning resolving results of the pseudo-range difference and the phase difference.

Description

Technical field [0001] The invention belongs to the technical field of satellite navigation ground-based enhancement systems, and in particular relates to a satellite navigation ground-based enhancement system differential positioning test method and equipment. Background technique [0002] China's Beidou satellite navigation system is a satellite navigation system independently developed and established by my country. It is the third mature global satellite positioning and communication system after the US GPS and Russian GLONASS. The system is composed of the space terminal, the ground terminal and the user terminal. It can provide high-precision, high-reliability positioning, navigation, and timing services for all kinds of users around the world, all-weather and all-time. It also has short message communication capabilities and can be applied to Civil and industrial fields such as navigation, aviation, surveying and mapping, and precision positioning. [0003] For the applicat...

Problems solved by technology

However, in the existing technology, testing the differential product quality and positioning results of the Beidou ground-based augmentation system usually requires different test equipment due to the difference in the differential positioning mode, that is, receiving and processing the three types of differential data requires three types of equipment. , that is, receiving and processing single-frequency pseudo-range differential data requires single-frequency pseudo-range test equipment, receiving and processing single-frequency carrier differential data requires single-frequency carrier test equipment, receiving and processing dual-frequency carrier differential data requires dual-frequency carrier test equipment

Therefore, in practical applications, it is inconvenient for test operation, data processing, carrying, installation and fixing, etc.
