The History of the Development of British Satellite Broadcasting Policy, 1977-1992
THE HISTORY OF THE DEVELOPMENT OF BRITISH SATELLITE BROADCASTING POLICY, 1977-1992 Windsor John Holden —......., Submitted in accordance with the requirements for the degree of PhD University of Leeds, Institute of Communications Studies July, 1998 The candidate confirms that the work submitted is his own and that appropriate credit has been given where reference has been made to the work of others ABSTRACT This thesis traces the development of British satellite broadcasting policy, from the early proposals drawn up by the Home Office following the UK's allocation of five direct broadcast by satellite (DBS) frequencies at the 1977 World Administrative Radio Conference (WARC), through the successive, abortive DBS initiatives of the BBC and the "Club of 21", to the short-lived service provided by British Satellite Broadcasting (BSB). It also details at length the history of Sky Television, an organisation that operated beyond the parameters of existing legislation, which successfully competed (and merged) with BSB, and which shaped the way in which policy was developed. It contends that throughout the 1980s satellite broadcasting policy ceased to drive and became driven, and that the failure of policy-making in this time can be ascribed to conflict on ideological, governmental and organisational levels. Finally, it considers the impact that satellite broadcasting has had upon the British broadcasting structure as a whole. 1 TABLE OF CONTENTS Abstract i Contents ii Acknowledgements 1 INTRODUCTION 3 British broadcasting policy - a brief history -

Altogether, NASA conducted 20 launches in 1978, mainly for other organizations or agencies. It was the third year in NASA history with a 100 per cent launch . success record. Most of the orbited payloads were for the application and benefit of users on Earth. The year also was one with major milestones in preparations for the crew-carrying Space Shuttle mis.- sions scheduled to start late in 1979. - more - Space Science With the Pioneer Venus mission, the United State con- tinued its systematic program of exploration of the solar system and beyond. Launched on May 20 and August 8, respectively, Pioneer Venus 1 and 2 arrived in the vicinity of Venus in early December to begin the most detailed scientific examination ever conducted of that cloud-shrouded planet. Pioneer Venus 1 was inserted into orbit on .Dec. 4 to make'measure.-- - ments and take pictures for at least eight months. The array of instrumented probes which comprised Pioneer Venus 2 arrived on December 9 and began their hour-long descent through the murky Venusian atmosphere at widely separated points. -

Attitude and Orbit Control for Satellite Broadcasting Missions
Proc. Indian Acad. Sci. (Engg. Sci.), Vol. 3, Part I, March 1980, pp. 47-65. Printed in India. Attitude and orbit control for satellite broadcasting missions C A MARKLAND Attitude and Orbit Control Division, European Space Research and Technology Centre, Noordwijk, The Netherlands M S received 3 July 1978; revised 5 February 1979 Abstract. This paper gives a broad introduction to the problems of attitude and orbit control of geostationary communications satellites. It specifically discusses the relationships between the satellite user's requirements for a broadcasting mission and the design of the attitude and orbit control system. To put the subject in perspective, a brief review of past and present satellites is presented first. Then orbit control is described in terms of the forces that act on a satellite in geostation.~ orbit _and the necessary station-keeping strategies. The design of attitude control systems for tlaree-ax~sstabilised satellites is presented by considering the disturbance torques, attitude sensors and actuators and by identifying the various system problems and their solutions.. Sources of error in pointing the satellite towards the earth are discussed together with the formulation of error budgets. Finally, the design approach for missions that require extremely accurate pointing is considered, and some remarks are given regarding the achievable accuracy for this class of satellite missions. Keywords. Communication satellites; twenty-four hour orbits; orbit perturbations; station-keeping; attitude control; angular momentum; attitude indicators; accuracy; satellite broadcasting missions; broadcast satellite. 1. Introduction The purpose of this paper is to give a broad introduction to attitude and orbit control of geostationary satellites and, in particular, to discuss the connections between the mission requirements imposed upon a broadcast satellite and the design of the corresponding attitude and orbit control system (AOCS). -
