The SACI-1 was a microsatellite of scientific applications, designed, developed, constructed and tested by Brazilian technicians, engineers and scientists working in INPE (National Institute of Space Research). SACI-1 was launched on October 14, 1999, from the Taiyuan Satellite Launch Center, China, by means of a Long March 4B rocket, as a secondary payload at the CBERS-1 launch.
The "SACI" satellites are composed of a multi-mission platform and a set of experiments that constitute the payload. These satellites had the cooperation of several Brazilian and foreign institutions.
The SACI-1 scientific satellite has the following characteristics:
Although the launch went smoothly, and the intended orbit reached, SACI-1 did not come into operation, probably due to a failure in the solar panel control system.
