Abstract : The ISIS (International Satellites for Ionospheric Studies) programme is a joint US-Canada effort in which Canada is responsible for the design and construction of a series of four spacecraft that are launched by the United States. It was preceded by another joint programme, Alouette I. In order to provide background the paper describes the experimental make-up of Alouette I together with some of the system design considerations. Attention is then given to the general objectives of the ISIS programme and how these are being met by succeeding satellites in the series. The satellites described, both from the point of view of experiments and on-board facilities, are Alouette II (launched together with Explorer XXXI in a joint mission known as ISIS-X in November 1965), ISIS-I (launched January 1969), and ISIS-B (estimated launch date late 1970). The achievements of these satellites are then compared with the general objectives of the programme in order to discuss the conceptual design of the last satellite in the series, ISIS-C. (Author)
