- Abstract
This paper reviews a conceptual design of the space-based radio astronomy telescope serviced on orbit by specific spacecraft. The central problem of this project is the periodical resupply of helium for cooling a telescope’s low-noise amplifier. The results of assessment studies for the different schemes of refuelling along with technical feasibility are presented in the paper. A conceptual design of the servicing spacecraft and its specifications are evaluated. The proposed scheme of on-orbit servicing makes possible expanding radiotelescope’s operational life to 25-30 years.
