The micrometheroid influence estimate on the microaccelerations level onboard small spacecraft

The problem of estimating the impact of a particle of a space debris or a micrometeoroid in the solar cell panel of a small spacecraft is considered. Numerical modeling of the impact of particle penetration into the solar cell panel on the dynamics of a small spacecraft and the level of microacceleration of its internal environment have been simulated. As a prototype for numerical modeling, a small spacecraft "Aist-2D" was chosen. The obtained results testify to the significant influence of particle penetration into the solar cell panel on the level of microacceleration of the internal environment of a small spacecraft and the need to take this influence into account when carrying out gravitationally sensitive processes on its board.
