Kosmos 19 was placed into a low Earth orbit with a perigee of 267 kilometres (166 mi), an apogee of 487 kilometres (303 mi), an inclination of 49.0°, and an orbital period of 92.2 minutes. It decayed from orbit on 30 March 1964.
  
  Kosmos 19 was a prototype DS-P1 satellite, the third of four to be launched. It was preceded by the successful launch of Kosmos 6 on 30 June 1962, and a launch failure on 6 April 1963, and will be succeeded by Kosmos 25, which will be launched on 27 February 1964.
