Meteosat 1

 1977-108A


ESA's first geostationary meteorological satellite, Meteosat 1, was launched in Nov 1977. There has been some confusion about Meteosat's apogee motor. ESA bulletin 85 implies an Aerojet motor while other sources suggest a BPD motor, but the NASA pre-launch MOR confirms Meteosat 1 carried an Aerojet SVM-6A and that it was to be jettisoned after firing at first apogee. ESA Meteo Programs Office (MPO) operated the satellite via ESTEC and ESOC.
