of the properties of electromagnetic waves emitted, reflected or :diffracted by the sensed objects, for the purpose of improving natural resources management, land use and the protection of the environment; (b) The term "primary data" means those raw data that are acquired by remote sensors borne by a space object and that are transmitted or delivered to the ground :from space by telemetry in the form of electromagnetic signals, by photographic film, magnetic tape or any other means; (c) The term "processed data" means the products resulting from the processing of the primary data, needed to make such data usable; (d) The term "analysed information" means the information resulting from the interpretation of processed data, inputs of data and knowledge from other sources; (e) The term "remote sensing activities" means the operation of remote sensing space systems, primary data collection and storage stations, and activities in :processing, interpreting and disseminating the processed data. The Principles Relevant to the Use of Nuclear Power Sources in Outer Space (1992) "States launching space objects with nuclear power sources on board shall endeavour to protect individuals, populations and the biosphere against radiological hazards. The design and use of space objects with nuclear power sources on board shall ensure, with a high degree of confidence, that the hazards, in foreseeable operational or accidental circumstances, are kept below acceptable levels. ..." The Declaration on International Cooperation in the Exploration and Use of Outer Space for the Benefit and in the Interest of All States, Taking into Particular Account the Needs of Developing Countries (1996) "States are free to determine all aspects of their participation in international cooperation in the exploration and use of outer space on an equitable and mutually acceptable basis. All States, particularly those with relevant space capabilities and with programmes for the exploration and use of outer space, should contribute to promoting and fostering international cooperation on an equitable and mutually acceptable basis. In this context, particular attention should be given to the benefit for and the interests of developing countries and countries with incipient space programmes stemming from such international cooperation conducted with countries with more advanced space capabilities. International cooperation should be conducted in the modes that are considered most effective and appropriate by the countries concerned, including, inter alia, governmental and non-governmental; commercial and non-commercial; global, multilateral, regional or bilateral; and international cooperation among countries in all levels of development."
