Abstract

The task of conducting a space-based multicolor photometric all-sky survey of high and moderate brightness stars with an emphasis on high accuracy and uniformity of measurements was formulated a long time ago, but remains in demand to this day. It was assumed that such survey would be carried out on board the ISS (the Lyra-B experiment), but due to the end of the station’s operation in 2028–2030 his preparation was stopped. An application has been submitted to conduct a similar survey on board the Russian Orbital Station (ROS). However, ROS is noticeably different from the ISS; one of the main differences is the sun-synchronous orbit of the station. This article discusses in detail the changes that need to be made to the scientific equipment of the experiment and the methodology of a survey when transferring location of the experiment from the ISS to the ROS. The benefits and disadvantages of the new experimental location are considered.
