Stationed at 0 deg. Meteosat P2 is a geostationary meteorological satellite operating within the world wide network of the World Weather Watch of the World Meteorological Organization. Its main missions are: Imaging in the visible, IR and water vapour region of the spectrum; data reception from so-called Data Collection Platforms (DCPs); data distribution to meteorological services and other interested parties (research institutes, etc). Geostationary position 0 deg E. ESA designator ESA/88/02. Launch time 1119:33 UT.
AMSAT-OSCAR 13 was launched by the first test flight of the Ariane 4 launcher. Size 600 x 40 x 200 mm. AO-13 was the third in a series of Phase-3 type high-altitude, elliptical orbit amateur communications satellites. It was built by an international team of radio amateurs led by Dr. Karl Meinzer of AMSAT-Germany. It carried four beacon transmitters and four linear transponders. AO-13 also contained a digital communications transponder called RUDAK-1. However attempts to get the experiment operating failed. Operational life span was 8 years. Careful analysis of AO-13's orbit in early 1990 by Victor Kudelka, OE2VKW revealed that resonant perturbations exist which lead the satellite into a negative perigee altitude. The perigee was down to 150 km by August 1996 which drastically increased atmospheric drag on the satellite until it reentered the Earth's atmosphere December 5, 1996.

Stationed at 19.2 deg E; European coverage. Astra 1B provides TV coverage to Western Europe. The satellite is owned and operated by Société Europíenne des Satellites (SES), a private company formed in 1985. Astra 1B is the second in a network of four satellites. SES acquired Astra 1B from DBS Crimson Satellite Associates while still under construction by GE Astro Space (as Satcom K3). Astra 1B is colocated with Astra 1A, and doubled the number of channels provided by the Astra network. Spacecraft: GE 5000 platform.3-axis stabilisation with momentum wheels, magnetic torquers, Earth sensors and 20 blowdown monopropellant hydrazine thrusters. Solar arrays provide 4850 W BOL, 4 50 Ahr NiH batteries. GEO insertion provided by 2 500N bipropellant motors. Payload: 16 Ku-band transponders (with six spares)
