Studying the Possibility of Ensuring the Stabilization Accuracy Characteristics of an Advanced Spacecraft for Remote Sensing of the Earth

Аннотация

The possibilities of using of single-gimbal control momentum gyros (gyrodynes) in the control system of an advanced remote sensing satellite of the Earth are studied. The main difficulty arising in the phase of designing a composition of the motion control system for this satellite is that the gyrodynes currently produced in the Russian Federation have an angular momentum magnitude, considerably exceeding the value required for this satellite. The second circumstance is the limited range of the selected angular rate sensor, which hampers performing attitude maneuvers at high rates. Ways of solving these problems are considered and the possibility to ensure the required accuracies of stabilization in surveying the Earth’s surface is shown. The capability of this satellite to conduct areal and corridor surveys is demonstrated by the results of mathematical simulation.
