Abstract

The invention relates to the technical fields of the application and the parallel computation of a navigational satellite, in particular to a quick computation method of an occultation event of a parallel asterism. The method comprises the following steps of: navigating constellations, reading occultation asterism information, distributing satellite pairs according to an obtainable computation core, computing occultation event information accurately and finally, storing as an information file for subsequent occultation data processing. The method provided by the invention is applied to an occultation data processing system, is especially applied to the preprocessing process of a near-real-time (3 to 6h) occultation data processing system for computing the important part of the occultation event information, can enhance the computation efficiency of the process greatly and reduces the computation time greatly, thereby providing quicker data guarantee to the near-real-time application of occultation data applied to weather forecast and space weather forecast.

Description

technical field

[0001] The invention relates to the technical field of navigation satellite applications and parallel computing, in particular to a fast data processing method for parallel planet group occultation events. Background technique

[0002] Radio occultation technology was first used in astronomy to detect the atmospheric state of planets. The development history of planetary atmosphere detection was described in detail in Reference 1 (see Document 1). In 1965, Fischbach proposed to apply this technology to the earth Atmospheric detection thought (see document 2); Since then, Hardy et al. have carried out a large amount of theoretical research and simulation calculation work (see document 3), the successful construction of the US Global Positioning System (GPS, Global Positioning System) constellation in the early 1990s and Running facilitates the application of this idea in practice.

[0003] The use of GPS radio occultation technology to detect the state of the...
