Satélite de Coleta de Dados
series of Brazilian data collection and relay satellites
SCD Satélite de Coleta de Dados (SCD, Portuguese for "Data-Collecting Satellite") is a series of satellites developed in Brazil.
SCD-1
The first one, SCD-1, was launched on February 9, 1993. It was the first satellite designed, developed, and assembled entirely in Brazil. It remains in operation to this date, and as such it is the only autonomous spacecraft in continuous operation in Earth orbit for more than thirty years. SCD-1 was designed, developed, built, and tested by Brazilian scientists, engineers, and technicians working at National Institute of Space Research and in Brazilian industries. It was made to be launched with a Brazilian rocket in 1989. Once it was officially recognized that the rocket could not be completed until many years later, SCD-1, after undergoing minor adaptations, was finally launched with a Pegasus rocket made by Orbital Sciences. The rocket was launched from a B-52 airplane while flying over the Atlantic Ocean.
SCD-1 is an experimental communication satellite with an environmental mission. It receives data collected on the ground or at sea by hundreds of automatic data-collecting platforms (DCPs) and retransmits all the information in a combined real-time signal back to tracking stations on Earth.
The public source identifies “Satélite de Coleta de Dados” as series of Brazilian data collection and relay satellites. This brief keeps that definition visible, then builds a research path around Satélite, Coleta and Dados.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Satélite de Coleta de Dados”, the useful work is to connect “series of Brazilian data collection and relay satellites” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 4, 2026. The linked authority identifier is Q1444957. The first chronological checks are 1993 and 1989.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
