Abstract
Satellites in low-Earth orbit have complex missions involving various time-dependent attitude requirements. For instance, a satellite must point an antenna toward a ground station to communicate with Earth and point its solar panels toward the Sun to collect power. At the same time, the mission of a satellite may make certain attitudes desirable or unacceptable. These complex constraints on a satellite’s control design can be dealt with succinctly by Signal Temporal Logic (STL) specifications. In this work, we leverage the robustness degree metric on STL expressions—quantifying the degree to which an STL specification is satisfied by a signal— and formulate an optimization problem that maximizes the robustness degree to generate control trajectories for the small satellite IMPRESS. We utilize the smooth approximation of robustness degree and use a gradient-based optimization framework to generate these control trajectories. The proposed approach is validated on simulated data for a mission scenario involving communication with ground stations and maintaining onboard power.
