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.
