Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] see figure 1 , figure 2 , image 3 , a kind of micro-nano-satellite for ionospheric detection of the present invention is made up of outer spherical shell 1, radome 2, antenna 3, modular parts namely CubeSat4; Their mutual relationship is: outer spherical shell 1 and antenna The cover 2 is connected to form the spherical shell of the whole star; the antenna 3 is fixed on the outer spherical shell 1 and is enveloped by the radome 2; the CubeSat4 is fixed at the center of the whole star by the support rod 1d on the outer spherical shell 1.

[0036] The outer spherical shell 1 is composed of four parts: an upper spherical shell 1a, a lower spherical shell 1b, a connecting plate 1c, and a support rod 1d. The supporting shell structure is connected by the connecting plate 1c; the supporting rod 1d is composed of four identical rod structures, two of whi...

Abstract

A micro / nano-satellite for ionospheric probing is composed of an external spherical shell, antenna housings, antennas and a modular component, namely the CubeSat, wherein the outer spherical shell and the antenna housings are connected to form a spherical case of the whole satellite; the antennas are fixed to the external spherical shell and covered with the antenna housings; and the CubeSat is fixed to the center of the interior of the whole satellite through supporting rods on the external spherical shell. The micro / nano-satellite for ionospheric probing is a combination of the modular component and the customized components, is convenient to produce and machine, and has the advantages of low cost, simple structure, high universality and short production cycle. The micro / nano-satellite for ionospheric probing can probe ionized layers and the air density of atmosphere, thereby having high practicability. By the adoption of symmetrical distribution of the two omnidirectional antennas, the effect that the satellite can receive and dispatch signals in any posture is ensured, and requirements for a posture control system are reduced.

Description

technical field [0001] The invention provides a micro-nano-satellite for ionospheric detection, which relates to the requirement of using the micro-nano-satellite to detect the ionosphere and its energy structure, and belongs to the field of satellite structure design. Background technique [0002] The ionosphere is an important component of the sun-earth system. It not only protects the living things on the earth from the direct action of solar ultraviolet radiation and cosmic high-energy particles, but also reflects and scatters the radio waves propagating through the ionosphere. Effects such as absorption and refraction. There are strong coupling interactions between the ionosphere and other regions of the Sun-Earth system, including the Sun, interplanetary medium, magnetosphere, thermosphere and mesosphere. Due to the disturbance of the earth's space environment and various plasma instability processes caused by solar activities, there are irregular structures of differ...
