Embodiment Construction

[0031] An occultation atmospheric detection system based on the last sub-level cluster proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims.

[0032] The last stage left in orbit is the largest space debris produced by the launch vehicle, occupying precious orbital resources for a long time. At present, each launch mission rocket has a certain carrying margin. In this embodiment, the GNSS occultation atmospheric detection load is carried on the last sub-stage of different launch missions, and the GNSS occultation atmospheric detection with high temporal and spatial resolution is naturally formed after the main star enters orbit. The network can effectively solve the problems of long construction period and high cost of GNSS occultation detection constellations, and realize "mak...

Abstract

The invention discloses an occultation atmospheric detection system based on a tail sub-level cluster, and the system is characterized in that a GNSS occultation detection load is loaded on an orbit-remaining tail sub-level cluster provided with an orbit-remaining platform, and the orbit-remaining tail sub-level cluster comprises a plurality of orbit-remaining tail sub-levels on a sun-synchronous orbit task and an inclined orbit task; the orbit remaining tail sub-levels adjust the attitude through an orbit remaining platform, receive a direct signal of a GNSS navigational star and an ascending occultation signal and a descending occultation signal of GNSS occultation through a GNSS occultation detection load, and analyze parameter data including ionosphere electron density, atmospheric refractive index and temperature and humidity profile to realize atmospheric detection. The orbit remaining tail sub-level under high-density launch of a carrier rocket is fully utilized to carry out adaptive modification, the orbit remaining tail sub-level and an existing GNSS occultation detection satellite constellation form a giant hybrid detection network, and the temporal-spatial resolution and the detection precision of GNSS occultation atmosphere detection can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of atmospheric detection, in particular to an occultation atmospheric detection system based on the last sub-level cluster. Background technique [0002] The earth's atmosphere provides a natural barrier for the reproduction of life on earth and the development of human beings, and is one of the basic conditions for the survival of human beings and life on earth. With the continuous exploration of the unknown world, the scope of human activities has gradually extended to the middle and upper atmosphere and space, and the space atmospheric environment has become a new territory for human beings to compete for. Especially the development of manned spaceflight technology, there is an urgent need for human Carry out in-depth research and analysis on the basic properties and movement changes of the space environment, and accurately predict the space environment. Therefore, establishing a long-term stable, global...
