Security implications of remote sensing

Major technical advances in remote sensing have developed sophisticated systems with both extensive military and civilian applications. Not only the USA and USSR, but a growing number of other countries such as China, France, India and Japan are actively engaged in remote-sensing R&D. This article reviews the capabilities of civilian satellite technologies and programmes of various nations, and examines the implications for national and international security. Many states are concerned about the commercial availability of data on their economic resources and national security-related activities. A particular problem is the possible misinterpretation of remotely-sensed data.     

Orbiting spies—opportunities and challenges

The great improvement in civil observation satellite capabilities over the past two decades—such that the image quality of civil and military satellites is now converging—is demonstrated with the aid of illustrations. The advantages of such progress, eg. new tools for treaty verification, are discussed. Potential problems, including censorship and denial of access to images of one's own country, which may conflict with the UN Remote Sensing Principles, are also highlighted. It is suggested that work on an ASAT treaty should be made a priority for the future.     

Arms control and conflict observation satellites

Dr Jasani argues the urgent case for establishing an international satellite monitoring agency, with an arms control and conflict observation satellite (ACCOS). He gives examples of recent technology advances and cites the imminent major development of space weapons by the USA and the USSR as a pressing reason for setting up a verification and crisis control mechanism. Both Europe and the non-aligned nations are in a position to participate in orbiting an ACCOS.     

US national missile defence and international security: blessing or blight?

With the revival of the US national missile defence, there is a danger of jeopardising not only the existing arms control and disarmament process, but also some of the measures that are on the table in the United Nations for negotiations. Examples of these are the prevention of an arms race in outer space and the nuclear fissile materials cut-off agreement. In this paper, the missile defence issues are examined. It is suggested that, if the US builds a missile defence system that is allowed by the 1972 Anti-Ballistic Missile Treaty between the USA and Russia, it could achieve its goal of defending itself against a limited missile attack. With this kind of approach, it may be possible to save many of the long-standing bilateral and multilateral treaties and prevent the beginning of a new and much wider nuclear arms race.     

Could civil satellites monitor nuclear tests?

As the momentum for further cuts in nuclear weapons grows and fears of nuclear proliferation increase, the need to monitor nuclear testing is becoming more pressing. While military observation satellites are already used for this purpose, this article argues that greater independence and impartiality could be achieved through the use of civilian remote sensing satellites, whose images could be made available to the International Atomic Energy Agency (IAEA). How images from space are processed and interpreted is described, as is how civil satellites might be used to verify a comprehensive test ban treaty. Four options open to the IAEA for utilizing remotely sensed images are discussed.
