Yenisey A1 is an exprimental Russian geostationary satellite to evaluate new technologies, among them large diameter unfurlable antenna reflectors.

The pogram started under the name Luch 4, which was to be a russian follow-on relay satellite in the Luch series to supplement the Luch 5A and Luch 5B satellites.
