The Satélite Tecnológico ("Technologic Satellite" in English) or SATEC, was a microsatellite of scientific applications, designed, developed, built and tested by Brazilian technicians, engineers and scientists working at INPE (National Institute for Space Research).
The primary objective of SATEC was to test the technological equipment embedded in the VLS-1, providing more information for future applications.
The SATEC scientific satellite had the following characteristics:
- Format: parallelepiped with 61 cm x 66 cm x 66 cm
- Mass: 65 kilograms (143 lb)
- Orbit: Heliosynchronous
- Stabilization: By rotation at 120 rpm
- Precision: 1 degree
- Altitude: 750 kilometers
Payload
The instrumentation shipped in SATEC was as follows:
- Solar generator: Silicon cells generating 20 W
- Battery: Type NiCd – 5 Ah
- PCU: with linear series technology
- GPS receiver: adapted to the conditions of flight
- Transmitter: S-band with BPSK modulation
