It used the bus of the Yantar film-return satellites and a traditional camera not capable of matching the resolution of KENNEN’s mirror telescope. In addition to that, it carried an infrared camera for nighttime observations. The first-generation satellites (Yantar-4KS1 or Terilen), having an estimated resolution of 1 meter from an altitude of 200 kilometers, were launched nine times between 1982 and 1989. An improved second-generation satellite (Yantar-4KS1M or Neman) with sub-meter resolution saw 15 launches between 1986 and 2000. Flight duration was gradually increased from six months to over a year, but even that was much shorter than the multiple-year missions flown by America’s digital reconnaissance satellites. The satellites were capable of sending images to Earth via military data relay satellites called Geyzer.It was not until 1983 that the Soviet government gave the go-ahead for the development of a satellite that came closer in performance to KENNEN. For that purpose, the LOMO optical institute in Leningrad was ordered to build an optical system called 17V317 featuring a telescope with a mirror 1.5 meters in diameter. This was supposed to fly on two different types of satellites. One, called Sapfir, was to be built by TsSKB-Progress and placed into low orbits for close-look missions while the other, dubbed Araks (also known as Arkon), would be manufactured by NPO Lavochkin and fly in much higher orbits for area survey missions. Ultimately, Sapfir never made it off the ground and the two Araks satellites that NPO Lavochkin managed to launch in 1997 and 2002 both failed well before the end of their design lifetimes.&quot;&quot;[URL unfurl=&quot;true&quot;]https://www.thespacereview.com/article/4006/1[/URL]</blockquote>
