Abstract

Abstract:

The deployment strategies for "hub-and-spoke" configured tethered satellite formation are investigated in circular orbit. Firstly, the deployment dynamics model is established based on Lagrangian method under some reasonable assumptions. The dynamical coupling between the attitude of central body and the tether length is analyzed, and then the deployment strategies for the cases with and without gravity gradient compensation are developed. By planning the deployment rate and angular velocity of central body, the successful deployments are achieved. Finally, some mathematical simulations for the proposed strategies are implemented. The simulation results indicate that using the proposed deployment strategies, the configuration can be maintained effectively and steadily.

Key words: tethered satellite formation, attitude of central body, gravity gradient force, spinning deployment, configuration stability
