The satellite is a spherical-like unit about 1 meter in diameter and 70 kg in weight. On board the satellite, there is a Mode A transponder and two CW beacons, one of which consists of a broadcast bulletin board with 2 kilobytes of storage space. A remote control system and telemetry system also exist on the satellite. RS-15 does not have not orientation or attitude stabilization systems. 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 transponder bandplan and data: Uplink: 145.858 - 145.898 MHz - approx. 100 Watts EIRP Downlink: 29.354 - 29.394 MHz - up to 5 Watts Beacon 1: 29.3525 MHz - 0.4/1.2 Watts Beacon 2: 29.3987 MHz - 0.4/1.2 Watts RS-15 Orbital data: Orbit number: 3 Apogee: 2165 km. Perigee: 1885 km. Period: 127.45 min. Inclination: 64.59 deg. Time of ascent node: 8:56:17 utc Longitude of ascent node: 54.243 deg. West. More information about RS-15 will be given after a complete testing of all systems. Please send your reports and comments to the control station: RS3A P.O.

Jim notes that the time between passes is just over 2 hours and comments that it can be confusing with RS-10/11 going over at the same time, working the West Coast on RS-15 when the Midwest and East Coast are in the window on RS-10/11. Oscar, DJ0MY, reports monitoring RS-15 over eastern Europe between 13:41 UTC (AOS) until 14:10 UTC (LOS) on the same day of RS-15's launch. The signal strength comparable to that of RS10/11 and RS12/13. Oscar reported hearing on the main beacon CW 29.352 MHz uding this pass. During this pass, Oscar could not monitor any Amateur Radio activity on the transponder passband. Only Andy, RS3A, at the Russian command station was calling CQ around 29.358 MHz in CW. DJ0MY reports making the first European SSB QSO via RS-15 on 26-Dec-94 at 16:07 UTC on 29.375 MHz with EB8CHG, Werner on the Canary Islands from his QTH near Hannover in Northern Germany. Both stations where the only ones using SSB at that time. There where other two stations operating in CW in the lower portion of the transponder passband. [Info via ANS and DJ0MY] * RS-15 OBSERVATIONS * ====================== Richard, G3RWL points out that the orbit of RS-15 is not sun-synchronous. As such, passes will not occur around the same time everyday, but will precess a small amount each day. The result is that in about three weeks time, the passes will come up about four hours earlier than they do at present. G3RWL also reports that RS-15's telemetry seems to be composed of sixteen groups with the callsign RS15 as a separator. The groups consist of three letters and two figures. He has also heard high-speed telemetry which *might* be the 1100 baud speed that fits the casette port on some Russian computers. Hi-speed data appears to be sent by ground command - it doesn't come down regularly. KA1LMX provided the following 2-line element set for tracking the RS-15 satellite: RS-15 1 23439U 94085A 94361.17042135 -.00000043 00000-0 00000 0 0 81 2 23439 64.8325 173.1633 0187416 292.2585 65.8559 11.27110522 128 * THANKS! * =========== Thanks to all those who sent messages of appreciation to SpaceNews, especially: N1MDZ N2GGQ G3IOR IW4CQI EI6EH F9XG All the best wishes for a great 1995 from KD2BD! :-) * FEEDBACK/INPUT WELCOMED * =========================== Mail to SpaceNews should be directed to the editor (John, KD2BD) via any of the following paths: FAX : 1-908-747-7107 PACKET : KD2BD @ KS4HR.NJ.USA.NA INTERNET : kd2bd@amsat.org -or- magliaco@pilot.njin.net SATELLITE : AMSAT-OSCAR-16, LUSAT-OSCAR-19 MAIL : John A.
