Operations

Operational Requirements

Progress TCV nominal propulsion system; Ground facilities of radio observation - incoherent dissipation radar of Solar-Terrestrial Physics Institute, Siberian Center of the Russian Academy of Sciences (Irkuts).

Operational Protocols

Determination of parameters (reflecting characteristics, sizes, density etc.) of large-scale plasma formations arising during operation of Progress TCV vernier thrusters and positioning and attitude control thrusters with different directivity of thruster plumes w.r.t. SC motion direction. Adaptation of the physical model of plasma sheath forming in the SC vicinity as applied to the Progress TCV. Study of interaction of plasma formations around low-orbit SC with ionospheric drag and solar radiation. Analysis of the impact of PS plume exhaust on the radio configuration of a low-orbit SC by comparing the Progress TCV reflecting characteristics when thrusters are operating and not operating.
