Time Fixed Rendezvous By Impulse Factoring With An Intermediate Timing Constraint written by Richard N. Green and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1974 with Orbital rendezvous (Space flight) categories.
A method is presented for factoring a two-impulse orbital transfer into a three- or four- impulse transfer which solves the rendezvous problem and satisfies an intermediate timing constraint. Both the time of rendezvous and the intermediate time of alinement are formulated as any element of a finite sequence of times. These times are integer multiples of a constant plus an additive constant. The rendezvous condition is an equally constraint, whereas the intermediate alinement is an inequality constraint. The two timing constraints are satisfied by factoring the impulses into collinear parts that vectorially sum to the original impulses and by varying the resultant period differences and the number of revolutions in each orbit. Five different types of solutions arise by considering factoring either or both of the two impulses into two or three parts with a limit of four total impulses. The impulse-factoring technique may be applied to any two-impulse transfer which has distinct orbital periods.

An error analysis is formulated to be used to determine the accuracy with which an orbit can be achieved with a single corrective impulse. This analysis can be used to determine the effects of uncertainties in navigation and maneuver implementation on various parameters of the final orbit. The equations which are derived in the analysis are programmed for the CDC 6000 series digital computers so that numerical results may be obtained more easily. This program is called Program OPERA.

This book studies several problems related to the analysis of planned or possible spacecraft missions. It is divided into four chapters. The first chapter is devoted to the computation of quasiperiodic solutions for the motion of a spacecraft near the equilateral points of the EarthOCoMoon system. The second chapter gives a complete description of the orbits near the collinear point, L 1, between the Earth and the Sun in the restricted three-body problem (RTBP) model. In the third chapter, methods are developed to compute the nominal orbit and to design and test the control strategy for the quasiperiodic halo orbits. In the last chapter, the transfer from the Earth to a halo orbit is studied. Contents: Quasi-periodic Solutions Near the Equilateral Points of the Earth-Moon System; Global Description of the Orbits Near the L 1 Point of the EarthOCoSun System in the RTBP; Quasi-periodic Halo Orbits; Transfer from the Earth to a Halo Orbit; Appendices: The JPL Model; Reference Systems and Equations of Motion; The Model Equations Near the Equilateral Points in the EarthOCoMoon System; Transfer Between Halo Orbits of the RTBP. Readership: Applied mathematicians, computational physicists and aerospace engineers.

"A computer program has been designed which determines the minimum-burn-time, thrusting, transfer trajectory between two Keplerian orbits. The minimization equations are formulated with constant Lagrange multipliers and solved numerically with the Newton-Raphson method. The solution obtained in this paper is not truly optimum because the control vector has been restricted to constant values (i.e., to be optimum the control vector should be a function of time)."--Page i

A multiple-impulse function is represented as a sequence of single-impulse functions. The single-impulse transfer which yields the velocity change required to transfer from a specified initial orbit to a partially specified final orbit is developed. Analytic derivatives of the function are obtained for use in optimization techniques. A four-impulse transfer is outlined. The analytic derivatives may allow more efficient optimization than numerical derivatives do.
