Safety-Aware Optimal Attitude Pointing for Low-Thrust Satellites
نویسندگان
چکیده
In geostationary orbit, long eclipses and the seasonal variations in direction intensity of solar input can cause damage to sensitive equipment during attitude maneuvers, which may inadvertently point towards Sun. The requirement that transmitting receiving antennae remain pointed Earth creates further restrictions pointing directions. aim study is construct a novel geometric reinforcement-learning-based method determine guidance maneuvers maintain safe operational orientations throughout an maneuver. trajectory computed numerically using framing Pontryagin’s maximum principle applied vehicle kinematics global matrix Lie group representation on SO(3), angular velocities are shaped free parameters. values these parameters determined by reinforcement learning algorithm avoid forbidden areas while maintaining (modeled as subsets two-sphere all possible directions particular axis). model geosynchronous satellite demonstrated simulation.

Attitude Determination for Small Satellites with Modest Pointing Constraints
This monograph reports on the development of the attitude determination backbone of the Ionospheric Observation Nanosatellite Formation (ION-F). Three spacecraft with similarly modest pointing constraints comprise the ION-F constellation. Pointing requirements for the constellation are dictated by the formation flying mission objective and communication demands. To satisfy pointing requirements...
متن کاملDynamic Modeling for Earth – Pointing Satellites to Control the Three – axis Attitude without the Attitude Information of One Axis
Various methods are presented to control the attitude of satellite due to lack of information of yaw axis attitude so far. In this paper, a new method is used which is more general and is applicable to all types of satellites, with at least one controller. This method is not limited to YAW axis and can control the two other axes as well. One feature of this approach is the ability to be modi...

متن کاملLow-Thrust Optimal Orbit Raising with Plane Change
A new guidance scheme for the problem of Low-thrust transfer between inclined orbits is developed within the framework of optimal control theory. The objective of the guidance scheme is to provide the appropriate thrust steering program that will transfer the vehicle from an inclined low earth orbits to the high earth orbits. The presented guidance scheme is determined using Pontryagin’s princi...
