... concept of spacecraft propulsion using Lorentz force is investigated for LEO formation flying. A triangular spacecraft formation configuration is used to simulate and validate the advantages and disadvantages of the proposed concept. It is illustrated that simple formation manoeuvres can be performed solely using ...

This paper presents an overview of Coulomb forces for propulsion of micro-spacecraft in swarms and ...

... Electrostatically charged spacecraft have been proposed for formation-flight applications in low-Earth orbit and geosynchronous Earth orbit. The inter-spacecraft Coulomb force acts internally on the formation and the induced geomagnetic Lorentz force provides an external ... where both forces have similar magnitudes. This combination of forces yields substantially different dynamical behavior than either force acting alone. Notional Coulomb-Lorentz spacecraft formations are introduced that use both forces in a complementary manner for formation control and ...

Today, those mechanical means are replaced ... formats vehicle data telemetry for transmission back down. Just as there many different kinds of sensors onboard the spacecraft, there are also many different kinds of actuators that can be used ...
