The Spektr RG observatory operates in a halo orbit around the Sun Earth L2 Lagrange point, 1.5 million km from Earth, a vantage point it has occupied since 2019. It relies on solar arrays manufactured by RESHETNEV as the backbone of its power system.
Over 6.5 years, the observatory has completed eight full sky surveys, observed dozens of deep space objects, and conducted a detailed scan of our Galaxy. The spacecraft has enabled the creation of the most comprehensive X ray map of the Universe to date.
Demonstrating consistent performance across missions, RESHETNEV built solar arrays now power multiple Lavochkin Association platforms — from the Spektr R astrophysics observatory to the operational Elektro L and Arktika M meteorological satellites.
Engineered for performance, RESHETNEV’s solar arrays integrate carbon fiber frames with string based substrates — a combination that delivers both durability and minimal mass. Modern photovoltaic cells further enhance the system, maximizing the conversion of sunlight into usable electrical power.
