The Spectr-RG space observatory was launched from Baikonur on July 13, 2019, and today is orbiting in the vicinity of the Sun-Earth libration point L2. The planned lifetime of the mission is 6.5 years and includes all-sky survey and pointed observations in the 0.3–15 keV band with the goal to create an X-ray map of the universe. This paper describes technical constraints of the mission, covering launch scenario, spacecraft design, ground data relay network, orbital and attitude control systems. First, the orbit correction scheme, applied for communication requirements, is presented. Then, the analysis focuses on a trade-off solution between attitude and orbit control operations. The proposed strategy allows mission to minimize the total propellant consumption by coordinated reaction wheels offloading and reducing the number and cost of the station-keeping manoeuvres to maintain the nominal orbit.
