Parus ( Russian Парус for "sail", GRAY index 11F627) is the name of a series of formerly Soviet and now Russian data relay satellites for predominantly military use. They are also known under the name Zikada-M and the manufacturer's name Zyklon-B and handle data communication with ships and submarines as well as their location. Because of their military character of the satellites Parus series receive a cosmos -Tarnbezeichnung used by Kosmos-3M rockets from Plesetsk brought out into space.

history

The development of the satellites as the successor to the cyclone system began in the 1960s and in 1967 the first flight tests of components of the system were carried out. The first satellite was launched on December 26, 1974 under the name Kosmos 700. In 1976 the system was officially put into service, which consists of six satellites each in orbits offset by 30 °. A spare satellite is normally available in each of these orbits, so that the system consists of twelve operational satellites. The 99th and so far last satellite of this series was launched on April 27, 2010 under the designation Kosmos 2463.

The civil version of the Parus system was the Zikada series (GRAU index 11F643), the development of which began in 1974, first tests were carried out in 1976 and the satellites were launched from 1978. With a mass of 820 kg, the satellites were somewhat lighter than their military counterparts and allowed the signals to be handled more easily. Compared to the Parus system, only four satellites were used in 45 ° offset orbits. So far, 20 satellites of this type have been launched. The civilian Zikada series was shut down in November 2003. Some of the Zikada satellites (GRAU index 11F643N (Kosmos), 17F118 (Nadeschda)) have been equipped with a satellite-based search and rescue system for the COSPAS-SARSAT . Some of the satellites equipped with the Nadezhda (German hope) system were also launched under this name. A corresponding contract was signed on May 6, 1977 and on June 30, 1982 Kosmos 1383, the first satellite equipped with the system, was launched. In Kosmos 2315, the system was replaced by a more modern one of the course type. At Nadeschda-M, a new RK-SM type system, which is also installed on the Sterch satellites, was used.

technology

The drum-shaped satellites, which are twisted or gravitationally stabilized by a boom, weigh around 825 kilograms and have a diameter of around two meters. They are based on the KAUR-1 satellite bus and store (similar to the Strela satellites ) the received messages and send them out again over the target area. Data is transmitted in the VHF range at around 150 and 400 MHz, with continuously transmitted signals with position and orbit data allowing the ships to determine their position using Doppler shifts until the GLONASS system was introduced . The system achieved an accuracy of about 100 m, whereby only the repeated measurement of the signals during different orbits of the satellites brought a corresponding accuracy. The energy supply with around 200 watts of power is provided by solar cells on the outside of the satellites. The lifespan is about three to four years.
