Telezvezda (misja Gamma)

GAMMA mission launched on July 12, 1990, was a research in the field of high-energy (gamma/x-ray) astrophysics prepared jointly by Russia, France and Poland. The satellite was based on the Soyuz manned spacecraft. Poland provided the Telezvezda star tracker working together with the Gamma-1 telescope. It had a 6deg x 6deg field of view and a 5th stellar magnitude sensitivity. It had an angular resolution of 2arcmin making it possible to determine the Gamma-1 pointing direction with the same accuracy.
