Ionospheric occultation involves a radio beacon transmitter on a satellite propagating a near line-of-sight signal to a receiver on another satellite with a ray path passing trough the ionosphere. Satellites in low-earth-orbit perform GPS occultation

In this paper we investigate an approach that appears to scale to the small size needed for femtosatellite (commonly called “ChipSats”) drag make-up and even orbit raising with the added benefit of being propellantless. The approach uses a short,

Orbital energy of a spacecraft can be transferred into electrical energy using an electrodynamic tether. The energy can be stored or used immediately for onboard power. We developed an energy storage module for our simulation software, TeMPEST, that

Electrodynamic tethers can be used to generate power onboard spacecraft orbiting the Earth (or any other planetary body with a magnetic field), essentially "harvesting" energy from the orbital energy of the spacecraft. A key benefit of an electrodyna

The rapid growth of the orbital debris population poses an increasing threat to military, commercial, and civilian science spacecraft in Earth orbit. NASA, the DoD, ESA, and other organizations have begun to respond to this problem by imposing requir
