Accuracy assessment of microaccelerations simulation on the spacecraft 'Foton-M' no. 2 according to magnetic measuring instruments data

摘要

The accuracy of modeling the field of microaccelerations of the internal environment of the middle class spacecraft of the Foton type is evaluated. It is assumed that the data of onboard magnetic measuring instruments were used as initial data for modeling micro-accelerations. The analyzed spacecraft do not have large elastic elements. The assessment was performed taking into account the influence of the work of the target and supporting equipment on the accuracy of measuring the components of the Earth's magnetic field induction vector by airborne means. The presented assessment allows us to draw conclusions about the significance of the influence of the target and supporting equipment on a specific measuring instrument. It can be used in the design of promising technological spacecraft. With its help it is possible to analyze the accuracy of modeling the field of microaccelerations in the operating spacecraft provided that this simulation was based on data from onboard magnetic measuring instruments.
