Magnetic attitude control options for earth pointing small satellite by Mohd Suhadis, Nurulasikin

“…The active magnetic attitude control technique is a promising attitude control option for small satellites operated in Low Earth Orbit (LEO). It is accomplished using sets of magnetic torquer that can generate a mechanical torque thus producing control actions when the torquers interact with the geomagnetic field. …”

Evaluation of Ionospheric Delay for Moon-Based Repeat-Pass InSAR Based on International Reference Ionosphere Model by Kai Wu, Huadong Guo, Guang Liu, Wenjin Wu, Yixing Ding, Guoqiang Chen

“…However, it faces a greater challenge when the signal passes through the ionosphere compared with the low Earth orbit (LEO) satellite. In this study, we constructed a total electron content (hereafter referred to as TEC) calculation model for the propagation path of a moon-based SAR signal based on International reference ionosphere model and moon-based SAR interferometry (InSAR) geometry. …”

Using MEPED observations to infer plasma density and chorus intensity in the radiation belts by William J. Longley, Anthony A. Chan, Allison N. Jaynes, Scot R. Elkington, Joshua M. Pettit, Johnathan P. J. Ross, Sarah A. Glauert, Richard B. Horne

“…These plasma parameters in the radiation belts are spatially localized and time-varying, so we construct event-specific diffusion coefficients using MEPED (onboard POES/MetOp) measurements of electron fluxes at low Earth orbit. This new method provides realistic diffusion coefficients for chorus waves that account for changes in the wave intensity, the plasma density, and the magnetic field strength in the outer radiation belt. …”
