Designation 23439 / 94085A
Launch date 26 Dec 1994
Country of origin CIS
Mission Telecommunications
Perigee/Apogee 1881/2163 km
Inclination 64.8°
Period 128 min
Launch vehicle Rokot #1

All the electronics onboard the satellite was designed and built by a group of Radio Amateurs from the town of Kaluga (180 km SW of Moscow) under the leaderships of Aleksander Papkov. The work was coordinated and supervised by NILAKT POSTO (aero-cosmic laboratory), Moscow, under the direction of Valentin Yamnikov. Full control of RS 15 as well as RS 10/11 and RS 12/13 is implemented by the RS3A control station at Moscow (headed by Leonid Maksakov).

RS-15 suffered from power supply problems, as it goes off almost immediately upon entering earth eclipse, not to return until is 'sees' sunlight again.
