A SPACECRAFT ATTITUDE DETERMINATION AND CONTROL ALGORITHM FOR SOLAR ARRAYS POINTING LEVERAGING SUN ANGLE AND ANGULAR RATES MEASUREMENTS

A Spacecraft Attitude Determination and Control Algorithm for Solar Arrays Pointing Leveraging Sun Angle and Angular Rates Measurements

The capability to orient the solar arrays of a spacecraft toward the Sun is an ultimate asset for any attitude determination and control subsystem (ADCS).This ability should be maintained in any operative circumstance, either nominal or off-nominal, to avoid the loss of the entire space-borne system.The safe mode implementation should guarantee a p

Impact of the extremely warm Gulf Stream on heavy precipitation induced by Hurricane Sandy (2012) during its extratropical transition

This study investigated the role of the extremely warm sea surface temperature (EWSST) over the Gulf Stream (GS) in heavy precipitation induced by Hurricane Sandy in October 2012 during its extratropical transition (ET).A control (CTL) run with observed SST and a climate (CLM) run with climatological SST over the GS were performed using a high-reso
