Pion
The Pion satellites were small satellites to calibrate ground tracking systems and to measure the atmospheric density.
These satellites were 70 cm spheres with a weight of about 50 kg. They carried a battery powered transmitter. The orbital lifetime was about two months. Six satellites were launched in pairs as piggy-back payloads on three Resurs-F missions.
