Embodiment Construction

[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] to combine figure 1 , the present invention provides a navigation satellite constellation compatibility and interoperability analysis method, comprising the following steps:

[0033] Step 1: Define constellation compatibility;

[0034] Constellation compatibility means that normal working navigation satellites, decommissioned navigation satellites and upper stages will not collide with other navigation system satellites. Constellation compatibility is mainly analyzed from two aspects of long-term evolution and collision probability. The invention provides the photographic infl...

Abstract

The invention provides an analysis method of constellation compatibility and interoperability of navigation satellites and relates to a definition and analysis method for the constellation compatibility and the interoperability of the navigation satellites. The compatibility is analyzed mainly from two aspects of long-term evolution and collision probability. Shot effects and long-term evolution rules of satellites on the medium orbit are given and a calculation method of the collision probability is provided. The interoperability is analyzed mainly from aspects of satellite visibility, position precision factors and positioning service availability, and calculation methods and effect factors of the satellite visibility, the position precision factors and the positioning service availability are provided respectively. According to the invention, the provided definitions of the constellation compatibility and the interoperability are different from definitions of common signal, time and coordinate compatibility and interoperability, and the provided analysis method is highly realizable in engineering.

Description

technical field [0001] The invention belongs to the technical field of global satellite navigation system compatibility and interoperability, and in particular relates to a navigation satellite constellation compatibility and interoperability analysis method. Background technique [0002] With the development of the Global Navigation Satellite System (GNSS), compatibility and interoperability have increasingly become a research hotspot in the field of navigation. The academic community has not yet given a clear definition of compatibility and interoperability. It is generally believed that: compatibility Sexuality refers to the separate or comprehensive use of multiple GNSS and augmentation systems, which will not cause unacceptable interference and will not harm the operation and services of other single satellite navigation systems; interoperability refers to the comprehensive use of multiple GNSS and augmentation systems, At the user level, better services can be obtained...
