Satélite Tecnológico
The Satélite Tecnológico or SATEC, was a microsatellite of scientific applications, designed, developed, built and tested by Brazilian technicians, engineers and scientists working at INPE.Features
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:
- 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
Mission
SATEC, which had an estimated life of 6 months, was lost with UNOSAT in the explosion of the VLS-1 launch vehicle on 23 August 2003 in an explosion three days before the launch date. This event came to be known as Accident of Alcantara.
