As Ariane 2/3 with stretched first (61%) and third stages, strengthened structure, new propulsion bay layout, new avionics, Spelda dual-payload carrier. The basic 40 version uses no strap-on motors (see Ariane 42L, 44L, 42P, 44P, 44LP for figures on varous combinations of solid and liquid propellant strap-on motors). A fully fueled Ariane core cannot lift off the ground without strap-on liquid or solid motors. When Ariane 4 is launched in this configuration, the propellant tanks of the first and second stages are not completely filled. Development was authorised in January 1982, with the objective of increasing payload by 90%. Total development cost 476 million 1986 ECU's.

Customer: SateLife. Store and forward communications satellite operating in the SatelLife 'HealthNet' LEO satellite communications network for remote regions. Still operational as of 2000.
Healthsat - II joined UoSAT-3/HealthSat-I as the second microsatellite in the HealthNet global communications system of SatelLife, a U.S. not-for-profit organisation. HealthNet, which was licensed in eighteen countries in Africa and Latin America, was providing desperately needed low cost 'last mile' communication links between medical institutions and health programmes in the developing world.
The HealthSat-II mission was completed, from concept to launch, within one year. SSTL were responsible for all the programmatic aspects of the mission including procuring the launch slot on the Ariane ASAP and arranging suitable insurance for the launch and early commissioning phase - all within a total contract price of £1M. Additional Details: Healthsat 2.
ITAMsat was built by AMSAT-ITALY. Its mission was to store and forward amateur radio messages.
KITSAT-OSCAR 25 was a South Korean experimental microsatellite based on the SSTL UoSAT bus built by the Korean Advanced Institute of Science and Technology (KAIST). KO-25 was operated from The Satellite Technology Research Center (SaTReC) in South Korea. KO-25's mission was to take CCD pictures, process numerical information, measure radiation, and receive and forward messages. The Infrared Sensor Experiment (IREX) was designed to acquire I/V characteristics of IR sensors. A passive cooling structure was devised for this experiment. KO-25 was eventually operated purely as a packet store-and-forward satellite.
Portugal's first satellite achieved through a technology transfer programme with Surrey Satellite Technology Ltd. Carried store and forward, DSP communications, GPS and Earth observation payloads. Still operational in 2000. Additional Details: Posat 1.
deg E.uropean Remote Sensing; carried SAR; ocean, land, ice, and atmospheric observations.
Caracterisation de l'Environnement Radioelectrique par un Instrument Spatiale Embarque; examined Earth RF environment. Customer: Alcatel Espace/DME. French government research payload incorporated into an advance microsatellite platform. Still operational as of 2000.
Universidad Politecnia de Madrid Satellite; experimental communications, microgravity experiments.
Developed by Matra Marconi Space/Toulouse for CNES, the satellite provided 10-m resolution images with a wide field of view. SPOT 4 also carried a wide field 'vegetation' imager and a laser communications experiment. Launch was by an Arianespace Ariane 40 rocket, the base Ariane 4 model with no strap-on boosters. The liquid hydrogen fuelled third stage of the Ariane 40 entered an 800 km sun-synchronous orbit together with SPOT 4.
Customer: Alcatel Espace(France). French government military electronic intelligence research payload incorporated into an advance microsatellite platform. Based on CERISE with enhanced EMC subsystem. Still operational as of 2000.
