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.
