Спутник связи. Molniya 3-53. [Редактировать]

Молния-3 — советский, а позднее и российский спутник связи двойного назначения, разработанный НПО ПМ. Как и его предшественник КА «Молния-2», построен на базе спутниковой платформы КАУР-2 в и являлся частью Единой системы спутниковой связи (ЕССС) вместе с КА Радуга («Грань») и КА Радуга-1 («Глобус»). Кроме того, КА «Молния-3» служил для ретрансляции программ Центрального телевидения на сеть станций «Орбита».
Спутники выводились на высокоэллиптические орбиты с помощью ракеты-носителя Молния-М с космодрома Плесецк. Масса космического аппарата составляла 1740 кг, расчётный срок службы — 3 года. Спутники предоставляли фиксированную связь, осуществляли функции телевещания, обеспечивали правительственную связь.
Начиная с 2006 года постепенно заменяется на КА нового поколения «Меридиан».

КА «Молния-3» строился на базе космической платформы КАУР-2. Она состояла из цилиндрического гермоотсека со служебной и ретрансляционной аппаратурой, на котором крепились шесть откидывающихся панелей солнечных батарей, двигательная установка коррекции, имеющая форму усеченного конуса, антенны, внешние радиаторы системы терморегулирования, исполнительные органы и шар-баллоны с запасами азота системы ориентации. После выведения на рабочую орбиту, корпус спутника ориентировался продольной осью на Солнце, а антенны, установленные на выносной штанге, независимо наводились на Землю.

FLIGHT International, 16 January 1975 79 A PATTERN OF MOLNIYAS HELIOS A N D S Y M P H O N I E BULLETIN Europe's two most recent experimental spacecraft continue to function nearly perfectly. The German-US Helios flight has experienced only one minor difficulty, the antenna for experiment No 5, the plasma and radio wave investigation being conducted by the Universities of Iowa and Minneapolis, having failed to extend fully. As a result, although data arc being received it is proving difficult to assess their reliability. The Franco-German Symphonie, Europe's first communications satellite, is described by officials of main contractor MBB as working "110 per cent" perfectly. The first transmission of pictures relayed by the satellite between the two terminals at Raisting in West Germany and PleumeurBodou in France took place on December 30. They were found to have suffered no loss of quality whatever when compared with the originals. In the meantime, the second Symphonie flight model will have completed integration in eight weeks' time but a launch date has yet to be fixed. MBB is confident that the satellite will in fact be launched. The company says that the French and German Governments are "not averse" to the launch, although they assert that there are "other European interests" to be considered. The present system of Russian communication satellites, according to P. J. Perkins and G. E. Perry of Kettering Grammar School, consists of four pairs of active Molniya 1 and Molniya 2 satellites circling the Earth in orbital planes spaced at 90° intervals. The close proximity of each member of a pair can be seen from the table below which, based on data from the Goddard Space Flight Centre, gives the predicted times and longitudes of passage through the ascending node (the longitude at which a satellite, travelling north in its orbit, intersects the plane of the equator) for October 4 last year. The table also shows that the ascending nodes are situated close to 63°E, which gives the best pass over the Soviet Union. Since each Molniya has a 12hr orbit, the next pass takes place over North America. Only a part of this orbit, near apogee, is visible over the pole from the USSR. Satellite 7th 27th 26th 8th 10th 24th 25th 9th Time, GMT Molniya2 Molniya 1 Molniya 1 Molniya 2 Molniya 2 Molniya 1 Molniya 1 Molniya 2 0014 0051 0608 0610 1203 1208 1815 1830 L o n g i t u d e of ascending nod 63-6°E 59-6°E 64-1°E 63-5°E 63-9°E 63-9°E 61-8'E 61-0°E A simple method of monitoring the status of the system is to plot the right ascensions of the ascending nodes (that is, the position of these nodes relative to the "lines of longitude" on the unchanging celestial sphere rather than the moving system of Earth longitudes) against time. 25ih'Mplriya1 -27thMolniya1 10th IMoIniya 2-*-: 9ihtutolmya 2 — : teuill Operational Molniya 1 Previous Molniya 1 Operational Molniya 2 Recent repla 90 180 270 Right ascension, degrees This graph shows how pairs of Molniya I and 2 satellites circle the Earth together in orbital planes separated by 90°. Right ascension is the astronomer's way of expressing the longitude of stars and other celestial bodies relative to the fixed background of the sky. The orbital planes rotate at the rate of about \° a day so as to maintain stationary ground tracks over the Earth throughout the year, thus providing predictable communication coverage over Russia These show that on October 4 the operational Molniya 1 satellites were the 27th, 26th, 24th and 25th in the series, these having superseded the 22nd, 23rd, 19th and 21st respectively. In recent weeks the 26th Molniya 1 has been replaced by the 28th Molniya 1 which, together with the 8th Molniya 2, has been joined by the first Molniya 3. On December 21 the 11th Molniya 2 replaced the 7th Molniya 2.
