Yet Another CTB Verification Exercise
Using Commercial Satellite Imagery
In July 1996 Vipin Gupta and Frank Pabian published the landmark study "Investigating the Allegations of Indian Nuclear Test Preparations in the Rajasthan Desert - A CTB Verification Exercise Using Commercial Satellite Imagery." Using satellite imagery from a variety of sources available at that time, they drew a number of Conclusions and Implications for the future application of commercial high-resolution satellite imagery to the verification of the Comprehensive Test Ban Treaty. The verification aspects of the CTBT have long been the subject of controversy, and publicly available high-resolution satellite imagery is peripheral to the core arguments surrounding seismic monitoring of underground nuclear tests. While public imagery intelligence may provide a useful adjunct to seismic monitoring, the verifiability of the CTBT and the merits of the treaty more generally are not contingent on the performance of public satellite imagery exploitation.
More recent developments warrant a reconsideration of some of the conclusions reached in 1996 by Gupta and Pabian. In May 1998 India and Pakistan conducted a series of underground nuclear tests. And in September 1999 Space Imaging finally launched the first successful high-resolution commercial imagery satellite, which began operations in January 2000. The 1998 nuclear tests provide fresh subjects for imagery intelligence, and Space Imaging's IKONOS-1 satellite provides a new source for imagery intelligence. In addition, some Russian KVR-1000 product has become readily accessible through the TerraServer implementation.
