Chu, Q.P. (author), Zwartbol, T. (author), van Woerkom, P.T.L.M. (author)The objective of the present paper is to give an overview of spacecraft attitude determination with GPS. GPS receivers with single or multiple antennas nowadays are low-cost sensors that constitute a valuable complement to existing sensor suites. GPS has been widely used for positioning and vehicle navigation. However, using GPS as an attitude...report 1995

Pronk, Z. (author), van Woerkom, P.T.L.M. (author)Computer simulation and testing of zero-gravity operations in support of development of space structures becomes more and more standard. Yet, the need for hardware simulation and test facilities representing zero-gravity conditions remains necessary, because of the strong requirements for verification and validation of system responses and model...report 1995

Misra, A.K. (author), van Woerkom, P.T.L.M. (author)Large robotic manipulators are to play a key role in assembly, maintenance, and servicing of future complex inorbit infrastructures. The first generation space manipulator is the Canadian Remote Manipulator System (RMS), in orbit since 1981. A second generation of large space manipulators is presently under development, for use on the...report 1995

van Woerkom, P.T.L.M. (author), Guelman, M. (author), Ehrenwald, L. (author)The paper focuses on Indirect adaptive control of space robot manipulators when maneuvering payloads with Imperfectly known mechanical parameters. The objective Is to estimate system mechanical parameters during the maneuver Itself. The system bodies are rigid, and are concatenated by ideal, rotational Joints. Existing adaptive control laws are...report 1993

van Woerkom, P.Th.L.M. (author)Earlier work on the formulation of an efficient algorithm for the description of the dynamics of a generic, structurally flexible space manipulator, has resulted in a linear recursive, "Order-N" algorithm. It forms the basis for the multi-body simulation program REALDYN at NLR. Various theoretical results obtained since then, have been collected...report 1992

van Woerkom, P.T.L.M. (author)The paper considers the dynamics of flexible space manipulators carrying out relatively fast maneuvers. In the past, computer simulations of the dynamics of flexible space manipulators executing large movements sometimes lacked in accuracy, especially during fast maneuvers. This deficiency can be attributed to the neglect of second-order terms...report 1991

van Woerkom, P.T.L.M. (author)The report contains the development of the dynamics equations of a spacecraftmanipulator system with chain topology. The spacecraft may be flexible. The attached manipulator consists of an arbitrary number of links, connected by single degree-of-freedom rotational joints. None, any, or all of the links may be flexible. A rigid or flexible...report 1990

van Woerkom, P.T.L.M. (author)For the simulation of rigid spacecraft manipulator dynamics there exists efficient recursive software. Extension of this software for the simulation of flexible spacecraft-manipulator dynamics would have important advantages. In this paper the method of Equivalent Flexibility Modelling (EFM) is outlined. Each flexible body is re-modelled as a...report 1989
