This paper describes the satellite aided search and rescue system that provides services to save the lives at the distress or emergency regions. COSPAS - SARSAT is a satellite-based system designed to provide distress alert and location data to facilitate SAR operations. The ground receiver named as Local User Terminals (LUTs) is in charge of processing the incoming signal and determining the beacon position via Frequency Difference of Arrival (FDOA) and Time Difference of Arrival (TDOA) technique. A common method of calculating TDOA and FDOA is the Cross Ambiguity Function (CAF). This paper proposes the implementation of CAF map method, which is a simple method that reduces the processing complexity over CAF method and also as the ability to locate several beacons that eliminates the false location of beacons.

This paper, which is, to a large extent, a review, presents results of an analysis of the current status and future prospects for the development of our country’s manned spaceflight from the standpoint of RSC Energia as the prime organization in Russia in this field of science and engineering. It addresses the issues involved in the ISS Russian Segment deployment completion, which is to be achieved by the addition of three new modules currently being developed at RSC Energia: the Multipurpose Laboratory Module in 2020; the Node Module in 2021; Science and Power Module in 2022, and the development of an improved version of cargo spacecraft Progress-MS. It describes quick ISS rendezvous profiles for crew and cargo transportation spacecraft. It discusses the issues involved in improving the efficiency of the ISS Russian Segment utilization, commercialization problems and plans to expand scientific applied research. The paper explores the desirability of establishing a Russian orbital station after the ISS program completion. As a strategic outlook for the development of our country’s manned space flight the paper formulates proposals on the national program of lunar research and exploration. It summarizes RSC Energia’s proposals on the development of a multifunctional system for crew search and rescue during launches of manned spacecraft from Vostochny launch site. It discusses the results and problems involved in laying the scientific, engineering and manufacturing groundwork for the development of advanced manned space systems, including introduction of digital technologies, development of new instrumentation, use of composite materials, additive and robotic technologies. Key words: Manned spaceflight, ISS Russian Segment, commercialization of scientific research, Russian orbital station, lunar research and exploration program, crew search and rescue system, problems of laying the scientific and engineering groundwork.
