Class: Technology. Nation: Europe. Agency: European Space Agency. Manufacturer: Kayser-Threde, Munchen.

MAQSATs were mass model and technology satellites built by Kayser-Threde, Munich, and lofted during the test flights of the Ariane 5. MAQSAT-H was a dummy communications satellite instrumented to report the actual payload bay environment during launch. It also included the TEAMSAT technology experiment payload, developed by ESTEC. TEAMSAT ejected a subsatellite, the Young Engineers Satellite, also with several experiments. MAQSAT-B was a smaller dummy satellite in the lower bay of the SPELTRA dual launch adapter. On a later launch Maqsat-3 was a similar dynamic model of Eutelsat W2, instrumented and within the SPELTRA adapter.

MAQSAT Chronology


30 October 1997 MAQSAT-H/TEAMSAT Launch Site: Kourou . Launch Vehicle: Ariane 5. Perigee: 530 km. Apogee: 26,633 km. Inclination: 7.9 deg.

21 October 1998 Maqsat 3 Launch Site: Kourou . Launch Vehicle: Ariane 5. Perigee: 996 km. Apogee: 35,511 km. Inclination: 7.2 deg.

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.
