(10m space radio telescope)

Spektr-R is a 10m space Radio Telescope launched in 2011. Among its uses is to provide one end of Very-long-baseline Interferometry. Its elliptical orbit extends to 384,000km. It operates at 1.35, 6.0, 18.0, and 92.0 cm Radio Wavelengths.

Spektr-R is one telescope of the RadioAstron program which coordinates its use with Earth-based radio telescopes. It has the potential for extreme Angular Resolution (0.01 milliarcseconds), but requires a bright Radio Source because of Spektr-R's 10m dish, smaller than typical ground dishes.
