abstract = "This paper presents results of the research investigation
regarding the causes for temperature variation of the SCD-1
(data-collection satellite) by analyzing its thermal behavior
evolution throughout 13 years in orbit. SCD-1, the first satellite
designed and built in Brazil, was launched in 1993 and is still in
operation. A mathematical model has been developed to simulate
thermal behavior of SCD-1 in orbit, which was used as a working
tool during project design phase, and is presented here.
Temperatures of SCD-1 in orbit have been monitored and recorded in
the Control and Tracking Center (Sao Jos ~ e dos Campos, SP,
Brazil) since its launch. An analysis carried out at the missions
beginning showed that all the temperatures were within the ranges
predicted in model. Over the years, the battery, which is the most
temperature-sensitive equipment in the satellite, had an increase
in temperature approaching upper limit. A method has been
developed to investigate the causes of this upswing in which an
optimization routine linked to the mathematical model corrects a
selected set of parameters in order to adjust the theoretical
temperature values to the experimental values. By means of this
methodology, data from SCD-1 were analyzed from 1995 to 2005
period and it was concluded that the rise in temperature was
caused by an increase in internal battery heat dissipation and
absorptivity in solar spectrum of some of the external satellite
shielding, both consequences of a long-term degradation.",
