RS-15 Launch Report from Leo Maksakov dated 27 December 1994:

Moscow. Official report.

December 26, 1994 at 03:00 utc was launched Radio Amateurs satellite RS-15 from Baykonur space center. RS-15 launched by vehicle "Rokot". "Rokot" is made on base of rocketry boosters (1st and 2nd stages) of missile well known as SS-19 and new booster "Briz" (3th stage).

Satellite is spherical like unit about 1 meter diameter and his weight is approximately 70 kg. (used the same trunk as on RS-3 - RS-8). On the board exist transponder, two radiobeacons, CW - broadcast bulletin board (2kb), remote control system and telemetry system. The satellite have not orientation and stabilization systems.

All electronics onboard equipment was designed and realized by group of radio amateurs from Kaluga town (180 km s-w from Moscow) under leaderships of Aleksander Papkov. Common coordinations and supervisions to carry out by public organization NILAKT POSTO (aero-cosmic laboratory), Moscow, director Valentin Yamnikov. Full controls of RS-15 as RS-10/11 and RS-12/13 implemented by RS3A controls station at Moscow (head Leonid Maksakov). Sponsor of ground control station is "Unicom", Russia and "UTC", RI, USA.
