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).^[1] 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.

Features

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:

Format: parallelepiped with 60 cm x 40 cm x 40 cm
Mass: 60 kg
Orbit: heliosynchronous
Stabilization: by rotation (6 rpm)
Precision: 1 degree

Energy supply

Solar Cells: Gallium Arsenide (AsGa)
Dimensions: 3 panels of 57 x 44 cm
Efficiency: 19%
Power output: 150W
Nickel Cadmium (NiCd) Battery Cells
Voltage: 1.4 V
Capacity: 4.5 Ah
Remote control rate: 19.2 kbit/s
Transmission rate: 500 kbit/s
Antennas of edge: 2 of transmission and 2 of reception, type Microstrip
Operating frequency telemetry / remote control: 2,250 GHz / 2,028 GHz
Receiving antenna in Soil: 3.4 m in diameter

Mission

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.
