  • Maqsat 3 - . Nation: France. Agency: ESA. Manufacturer: Kayser-Threde. Class: Technology. Type: Navigation technology satellite. Spacecraft: MAQSAT. USAF Sat Cat: 25503 . COSPAR: 1998-059A. Apogee: 35,491 km (22,053 mi). Perigee: 1,017 km (631 mi). Inclination: 7.5000 deg. Period: 641.20 min.

    Maqsat 3 was an instrumentation package used to monitor performance of the Ariane 5 booster. At T+12:43 the Speltra adapter cover separated revealing Maqsat-3. At T+15:14 the EPS stage Aestus engine ignited and burned until T+31:00. At this point on a normal mission the satellite would separate from the EPS, but to avoid creating space debris Maqsat remained attached to the EPS. The EPS/Maqsat-3 was placed in a 1027 km x 35863 km x 7.0 degree geostationary transfer orbit.
