Application Of Aeroassisted Orbital Maintenance To Ultra-Low-Orbit Satellite

Currently,more and more attention have been put on low altitude orbiting satellite,.As its low altitude. When observed during high-resolution remote sensing. Can significantly reduce the payload weight and power consumption. Even the ordinary resolution of observation equipment will be able to achieve high-resolution observation. And can reduce the cost of satellite.To achieve mass production. Therefore the research on the low orbit satellites. Will have greater economic benefits and potential applications. However, due to its low altitude. Ultra-low-Orbit satellite faced gas aerodynamic forces that moments of magnitude higher compared to traditional satellites. Lead to the design life of ultra-low-orbit satellites is short. How to make full use of air power is a very worthy subject of study. In this paper,calculation of the precision gas aerodynamic forces and the use of the auxiliary air force to keep Ultra-low-Orbit.First, in this paper over the area of gas dynamics were studied, using DS3V software on a typical Ultra-low-Orbit satellites Analysis of aerodynamic field in the lean and dynamic pressure and characteristic area of the relationship.Second, calculated to fit the linear aerodynamic. Design a controller to keep Orbit.based on the Hill equation. the previous calculation of the aerodynamic force for the auxiliary track maintenance.The calculation of aerodynamic front for the auxiliary track maintenance.Finally.simulation to the orbit keep controller,.analysis of the use of Aerodynamic to track the maintenance of the feasibility and scope of application.
