A Glazko’s scientific contributions

Distributed satellite systems are used to achieve improved temporal and spatial resolution of observations, as well as higher response speed and reliability. Satellite networks with global coverage, which are not limited by geographical restrictions, have attracted the interest of the scientific community and industry. Next-generation satellite networks differ from previous satellite networks in that they have built-in processing, low-cost tracking antennas, and inter-satellite communications. This article describes a mission concept, featuring intersatellite communication link based on software-defined radio employing W-band frequencies. The increase in the frequency band to the W-band, E-band is due to the fact that frequency allocations in S, X, Ka, Ku bands get increasingly crowded and difficult to obtain. This study presents an approach to miniaturization of the electronics and antenna technology to ensure W-band communication. The theoretical limits of network throughput with limited size and available energy were explored and described. Several methods have been proposed to increase the payload and expand the network for inter-satellite and subscriber communications, digital signal processing and protocol stack, as well as the satellite subsystem. The current state of and prospects for the development of this technology are described. The purpose of the designed constellation is to provide higher data return, autonomous airborne navigation with less dependence on ground tracking data and significantly reduce the total operating costs of future research missions.
