About : 

  • The successful launching of APPLE (Ariane Passenger Payload Experiment) India’s first three-axis stabilised experimental communication satellite, using ARIANE launcher, on June 19, 1981, marks an important milestone in India‘s space programme. By positioning the APPLE Spacecraft in the three-axis stabilised mode in the geostationary orbit at 102ºE longitude on July 16, 1981 after carrying out complicated mission manoeuvres, India joined the ranks of nations who have developed their own three-axis stabilised geostationary communication satellites.
  • APPLE, with a launch weight of 673 Kgs. has a cylindrical structure of 1200 mm diameter with an overall height of 1985 mm. The spacecraft was designed and developed at the ISRO Satellite Centre (ISAC) of ISRO at Bangalore. This centre was also responsible for the overall management, the development of spacecraft structure, thermal, TTC, power, control and sensor systems, spacecraft integration, testing mission planning and launch and operationalisation.
  • The satellite, after integration and tests at the ISRO Satellite Centre, Bangalore, was transported to Toulouse, France, for compatibility tests with the METEOSAT and CAT satellites forming part of the composite ARIANE payload. The satellite was subsequently transported to Kourou, French Guyana, and after conducting final checks was integrated with the ARIANE launcher.
