The impedance properties required for an impedance controller that will ensure adequate probe-drogue contact time for docking are computed and are related with their mechanical counterparts. The docking of a robotic Chaser to a Target spacecraft is modeled using a multibody approach. In this work, the robotic impact docking between two space systems is considered. Successful docking is subject to a number of parameters and conditions. Impedance Control Design for On-Orbit Docking Using an Analytical and Experimental ApproachĪbstract: An important phase in On-Orbit servicing missions is robotic docking. This paper presents the approach that is actually being adopted in the development of the UoMBSat-1 picosatellite at the University of Malta. The hardware technology available is outlined and the applicable control laws and techniques are reviewed. This paper explores the implications of including a 3-axis attitude determination and control system with provisions for desaturation and detumbling within the confines of a PQ. However, the question remains on whether it is feasible to implement a fully-featured satellite within the far tighter constraints imposed by a PQ. The PocketQube (PQ) - one eighth the size of a CubeSat – aims to further reduce these costs. Keywords: Aerospace control, Control, Unmanned systemsĪbstract: The CubeSat form factor was very successful at reducing development and launch costs for spacecraft. Review and Feasibility of Active Attitude Control and Detumbling for the UoMBSat-1 PocketQube Pico-Satellite

This is applied to design a rest-to-rest two-impulse slew manoeuver and a slew motion using only two reaction wheels.

Following this, the virtual time is reparametrized. This is achieved using a three-step method in which the angular velocities are expressed as analytic functions in terms of free parameters (on the virtual time domain), and the boundary conditions on the rotation are matched using a shooting method based on a discretized form of Rodrigue’s formula. In this paper attitude guidance is considered which could be used, in addition to feedback control, to enhance the efficiency of slew motions by pre-planning time-dependent attitude motions. Keywords: Aerospace control, Algebraic and geometric methods, OptimisationĪbstract: Attitude slew motions for spacecraft are usually undertaken using feedback control where only the desired final attitude is stated.
