In this paper, the preferred region of design parameters for quasi-normalized equations of single-axis attitude control of rigid spacecraft using pulse-width pulse-frequency modulator (PWPFM) is presented for rest-to-rest maneuvers. Using the quasi-normalized equations for attitude control reduces the system parameters, that is, the moment of inertia, the filter gain, and the maximum torque of ...

Did you know that many birds use the San Francisco Estuary like a hotel, to rest during their long migrations? The is major stopover on Pacific Flyway—a huge path for migrating runs from South America Arctic Circle! Tons of waterfowl (ducks, geese, and shorebirds) make this journey every year.
