The space interferometer Radioastron is working jointly with the largest radio telescopes of the world. Ground tracking stations provide for retrieving the information and determining the orbital parameters for data processing centers. The project is aimed at systematic studies of images of radio emitting regions, their coordinates, and time-dependent variations near super-massive black holes in galactic nuclei, stellarmass black holes, neutron and quark stars, regions of star and planet formation in our and other galaxies, the structure of interplanetary and interstellar plasma, and the Earth's gravitational field. © 2012 Pleiades Publishing, Ltd.

The Russian Academy of Sciences and the Russian Federal Space Agency are planning to launch Radioastron in 2011, which is a unique space observatory with a 10-meter reflector antenna. In conjunction with the largest ground-based radio telescopes and tracking stations, it forms the first system that will be able to carry out studies with a resolution millions of times greater than that of eyesight. © 2012 Pleiades Publishing, Ltd.

The conditions for video transmission from the panoramic camera of the Mars-3 lander are analyzed. The latter is known to have made the first soft landing on Mars in 1973 during a severe dust storm resulting in damage to the lander. This damage is believed to have reduced the lander's operation time to 20 s and, apparently, prevented it from achieving the necessary orientation on the surface. If we assume that the lander is lying on its side, then the camera's panoramic axis would be not vertical, but nearly horizontal. In such a case, we can reproduce, by removing the noise and interferences from the video signal by modern methods, a panoramic fragment, which can help assess the structure of the surface near the landing site of Mars-3. © 2013 Pleiades Publishing, Ltd.

The techniques for estimating the powers of intermodulation interferences (the total power of interferences and the interference power within the signal band), which correspond to orthogonal frequency-division multiplexing (OFDM) signals at the output of a transmitter interpreted as an inertialess nonlinear device, are described. © 2014 Pleiades Publishing, Inc.
