Antenn System to Receive the Space Information in 137 MGh Range

The paper deals with the technical requirements for the antenna system designed for a station acquiring data from the domestic and foreign Earth observing spacecraft to be transmitted via the 137 - 138 MHz radio links to consumers. The technical requirements are the basis for all system facilities design and development: a turnstile antenna with an optimal directional pattern, a low - noise environment effect - protected (including lightning protection) amplifier, trunk amplifier enabling data acquisition at a distance of up to 1km from the antenna location, and a set of cables. The low - noise and trunk amplifiers are fed from computer through the +5V universal serial bus (USB) via high - frequency cables through a receiver (with appropriate decoupling at each level). The station software allows for satellite images to be acquired and replayed in real time. The example of such an image is given in this paper.
