General Consulting and Engineering, undated

General Consulting and Engineering, an Italian engineering consulting firm, hired Disher to assist them on a contract with the Italian CNR/PSN. This contract involved technical and management assistance to CNR/PSN for the Lageos 2 satellite project. The Lageos 2 satellite was launched into orbit by the Italian Research Interim Stage, or IRIS, an Italian CNR/PSN space program developed to oversee satellite missions. The first Lageos satellite was launched by United States in 1976. Its purpose was to measure the movements of the earth's crust and rotation. In 1982, NASA and CNR/PSN established a joint study group to consider the potential benefits of a second Lageos satellite. The group highly recommended such a satellite, feeling that much additional information on the earth and its rotation could be obtained. Materials in the sub-series date from 1981-1983 and include reports of the NASA/PSN study group, Disher's reports to and correspondence with General Consulting and Engineering and a CNR/PSN document explaining IRIS.
