Spacecraft

edit

The DS-A1 satellites were developed by Yuzhnoye to test the techniques and equipment for communication and navigation systems and performed radiation measurements. It had a mass of 315 kilograms (694 lb).[1]

Launch

edit

It was launched aboard the ninth flight of the Kosmos-2I 63S1 rocket.[4] The launch was conducted from Mayak-2 at Kapustin Yar on 20 October 1962 at 03:50:00 GMT.[5]

Mission

edit

Kosmos 11 was placed into a low Earth orbit with a perigee of 234 kilometres (145 mi), an apogee of 901 kilometres (560 mi), an inclination of 49.0°, and an orbital period of 96.1 minutes.[2] It decayed on 18 May 1964.[6] Kosmos 11 was the first of seven DS-A1 satellites to be launched.[3] The next DS-A1 launched will be Kosmos 17, on 22 May 1963.[7]
