Impact of Miniaturized Fixed-Bias Multineedle Langmuir Probes on CubeSats

Kinetic simulation results are presented to study the response of multineedle Langmuir probes of the type used on many satellites. Simulations of isolated probes are used to parameterize the current collected as a function of voltage for a set of densities and temperatures relevant to the Earth's ionosphere. These simulations also serve to assess the validity of analytic results obtained from the ...
