Priority Scientific and Technical Problems in the Field of Exploration and Efficient Use of Outer Space

The main directions of development of cosmonautics that influence the coherence of the Russian Federation are discussed. The key role of space navigation, space communications, and Earth remote sensing is shown. The importance of applied and basic research in space is emphasized. The trends in the field of applied cosmonautics are analyzed. Existing problems are described and ways to solve them that imply increasing the space constellation for scientific purposes and remote sensing of the Earth, improving the accuracy of positioning, availability, and noise immunity of space navigation.
