The purpose of this article is to popularize the idea of introducing a low-orbit supplement to the GLONASS system and to highlight the prerequisites for the creation and use of small spacecraft that have emerged recently. The analysis of the current state was carried out in contact with leading experts on this topic and on the basis of foreign public statements, including from the materials of international conferences. The text of the article highlights the urgent problems of the system and offers one of the new solutions. It can be assumed that in the coming years, small spacecraft and low-orbit groups consisting of a large number of such vehicles will create and occupy a completely new niche in the market of satellite services with the possible gradual displacement of their larger counterparts. The conditions for this will arise naturally: economic feasibility, operational convenience, etc. At the same time, the feasibility of introducing a low-orbit supplement based on small spacecraft to the GLONASS system requires additional research.
