Research of Stratospheric Satellite Orbit Control Modeling and Simulating
Computer Simulation, 2010Co-Authors: Fu Wen-xingAbstract:Static buoyancy provided by super-pressurized balloon,Orbit Control force provided by Strato-Sail,each force transferred by tether. Stratospheric satellite moves slowly toward east and west in given latitude. It is an excellent platform of communications and surveillance. The characteristic of stratosphere wind field is analyzed. The constitution and principle of stratospheric satellite is discussed. Using a model of lump-mass-and-spring,considering the super-pressurized balloon and Strato-Sail as the tether nodes,each component is modeled based on dynamic characteristic. Simulated by Matlab/Simulink,the Control method is studied to exploit the difference of wind velocity at different altitudes to generate lateral forces to Control latitude Orbit. Simulation results show that the Strato-Sail Orbit Control system can achieve the steady Control and adjust the latitude position of stratospheric satellite.

deploy work package 3 software requirements document for a distributed system for attitude and Orbit Control for a single spacecraft dep rp ssf r 006 issue 1 3
2011Co-Authors: Kimmo VarpaaniemiAbstract:This Software Requirements Document (SRD) expresses the functional requirements of the Software (SW) of the DEPLOY Work Package 3 (WP3) Distributed System for Attitude and Orbit Control for a Single Spacecraft (DSAOCSS). This system is in many ways similar to the centralized Attitude and Orbit Control System (AOCS) considered by http://deploy-eprints.ecs.soton.ac.uk/266/. However, there are differences up to the extent that the systems should not be assumed to have the same baseline for requirements. The actual Attitude and Orbit Control (AOC) in DSAOCSS is centralized in conventional Control-theoretical sense, so the term “distributed AOCS” is too ambiguous to be used in this context.

Application of Wi-Fi Wireless Network on Attitude and Orbit Control System of Satellite
Signal and Information Processing Networking and Computers, 2018Co-Authors: Jinpeng Wang, Yi Zhan, Mingyu Xie, Yue Wang, Jianzhao DingAbstract:This article analyzes the feasibility of applying Wi-Fi wireless network into Attitude and Orbit Control System (AOCS) based on the previous research of commercial wireless network. Moreover, this article analyzes the wireless transmission delay of WI-FI. And analyzed results are verified by running a specified experiment. In addition, this article proposes a new scheme of wireless AOCS and develops an AOCS with Wi-Fi network by employing modified spacecraft products with six newly developed modules. Furthermore, the simulation results are illustrated and critically analyzed.

Global optimum spacecraft Orbit Control subject to bounded thrust in presence of nonlinear and random disturbances in a low earth Orbit
The Egyptian Journal of Remote Sensing and Space Science, 2012Co-Authors: Tamer Mekky Ahmed HabibAbstract:Abstract The primary objective of this work is to develop an effective spacecraft Orbit Control algorithm suitable for spacecraft Orbital maneuver and/or rendezvous. The actual governing equation of a spacecraft Orbiting the earth is merely nonlinear. Disturbance forces resulting from aerodynamic drag, oblateness of the earth till the fourth order (i.e. J 4 ), and random disturbances are modeled for the initial and target Orbits. These disturbances increase the complexity of nonlinear governing equations. Global optimum solutions of the Control algorithm parameters are determined throughout real coded genetic algorithms such that the steady state difference between the actual and desired trajectories is minimized. The resulting solutions are constrained to avoid spacecraft collision with the surface of the earth taking into account limited thrust budget.
