Occultation atmosphere detection system based on tail sub-level cluster

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...
