Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0033] The static positioning method of the Mars lander based on the orbiter disclosed in the present invention, when the Mars lander lands on the surface of Mars, the orbiter is introduced as a relay station on the basis of the tracking and measurement of the lander by the ground measurement and control station, and the two-way measurement method is adopted. , to obtain the relative position relationship between the orbiter and the lander, and send the inter-satellite measurement data back to the earth ...

Abstract

The invention provides a static locating method for a mars lander based on a surrounder, based on tracking and measuring a detector, the wireless distance and speed measurement between the surrounder and the lander is measured; the surrounder emits a wireless signal in a manner of double-trip measurement; and after being in transparent transmission of the lander, the wireless signal is sent to the earth to be treated by the mars measuring data. The landing locating precision obtained by multi-circle measurement of the lander can reach dozens km magnitude. The static locating method for a mars lander based on a surrounder provided in the invention can help the ground tracking and measuring and make up the defects of long underground flame distance and hard tracking and measuring difficulty of the lander; and the use ratio of the equipment on the mars can be improved without increasing extract cost by the equipment on the surrounder.

Description

technical field [0001] The invention relates to a static positioning method for a Mars lander based on an orbiter, relates to a relay station mode, and belongs to the technical field of deep space exploration. Background technique [0002] Mars is a terrestrial planet in the solar system. The environmental conditions of Mars are the closest to those of the Earth. Studying Mars is conducive to further understanding the formation and evolution of the Earth and the solar system. Mars has an atmosphere and water ice exists on the surface. Searching for life is the current deep space Probe one of the most interesting targets. my country has embarked on plans to launch the first autonomous Mars probe to realize Mars exploration. The lander in the exploration mission will enter the atmosphere of Mars and land on the surface of Mars. Due to the lack of understanding of the Martian environment, the expected landing accuracy is limited. How to quickly and accurately determine the lan...
