Summary:
Ambient space plasma can induce electrostatic noise in a linear
antenna onboard a spacecraft. The noise intensity spectrum as a function of
frequency depends on the plasma parameters. The phenomenon can be utilised for
inferring the plasma parameters if one measures the induced noise by a
sensitive radio receiver. It has been demonstrated in several space missions
that the technique is able to uncover the correct plasma parameters. In PIANOS
project we assess to what extent the noise measurement technique could be used
to monitor key parameters of space weather in various relevant regions at low
cost. We review the properties of the target plasmas, consider different
antenna geometries and their deployment strategies as well as data analysis
methods and algorithms. To enable low-cost space weather monitoring by the
noise spectroscopy method, we recommend a roadmap of technology developments
activities including CubeSat demonstrations.
