Demonstration of 100 Gbps coherent free-space optical communications at LEO tracking rates
Free-space optical communications are poised to alleviate the data-flow bottleneck experienced by spacecraft as traditional radio frequencies reach their practical limit. While enabling orders-of-magnitude gains in data rates, optical signals impose much

After the SKA - Radio Astronomy in 2049 [PDF]
The concept of a Square Kilometre Array was developed to ensure that progress in Radio Astronomy in the early 21st Century continued at the same impressive pace as was achieved during the first 50 years. The SKA telescope is designed to pave that road to

Polygon “Simeiz-Katsively” - the cycles in the climatic and the geophysical characteristics of the Crimea [PDF]
Coherent variations are established with periods of about 10–12 years and 60–70 years, which are found in processes of different physical nature and can be attributed to global cycles in the solar system, the manifestation of which in climatic and ...
