Mars atmospheric ionosphere puncture detection trajectory optimization method, device and equipment

Abstract

The invention relates to a Mars atmospheric ionosphere puncture detection trajectory optimization method, device and equipment. The method comprises the following steps: constructing a lifting body aircraft motion equation for changing perigee argument for multiple times; establishing a conversion relation between ballistic parameters and orbit parameters; constructing a perigee argument equation, and obtaining a relationship between a perigee argument omega and a trajectory parameter; carrying out local sensitivity analysis on the perigee argument omega, taking a parameter which enables the sensitivity of the perigee argument omega to be maximum as an optimization variable, enabling the speed of the lifting body aircraft to be maximum when the lifting body aircraft flies out of the atmosphere every time, and determining the position of the lifting body aircraft when the lifting body aircraft flies out of the atmosphere by selecting different flying-out point latitudes phi; and optimizing the puncture detection flight trajectory based on a Gauss pseudo-spectrum method to obtain a required reentry trajectory. The problems that in an existing Mars atmospheric ionosphere detection mode, a detection area is one-sided, and the detectable range is limited are solved. The Mars atmosphere ionosphere detection device has the effect of more comprehensively detecting the Mars atmosphere ionosphere.

Description

technical field [0001] The present application relates to the technical field of deep space exploration, in particular to a method, device and equipment for optimizing trajectory of Mars atmosphere ionosphere puncture detection. Background technique [0002] Mars is the closest terrestrial planet to Earth in the solar system, so it has always been the first choice for human planetary exploration. Mars exploration is of great reference value for humans to understand and understand the evolution process of terrestrial planets, the causes of climate change, and explore the origin of life. [0003] Among them, the Martian atmospheric ionosphere is directly related to important activities such as communication between the Earth and Mars, and local communication on Mars, and is extremely important for using radar to find water sources on Mars. Therefore, it is important to detect and study the Martian atmospheric ionosphere. Theoretical significance and engineering value. [000...

AI Technical Summary

Problems solved by technology

[0005] However, direct detection has problems such as short observation time and one-sided detection area; indirect detection has low spatial resolution and cannot detect the fine structure in the Martian ionosphere, and the range of detectable solar zenith angles in the ionosphere is limited by the orbits of the Earth and Mars. limit

[0006] In view of the above-mentioned related technologies, the inventor believes that there are defects in the existing Mars atmospheric ionosphere detection methods, which have a one-sided detection area and a limited detectable range.
