With the increasing number of joint projects for spacecraft development, it is a necessity that an environmental test can be followed from remote locations. New technologies that have been created for the Internet environment, like Java and fast networking, may provide the appropriate framework to support the development of remote visualization software. However, there are fundamental issues that must be considered, like data acquisition systems interconnection, efficiency, security, and tools support the software analysis, project, and implementation. In this work we present the experience of the Brazilian Institute of Space Research/Test and Integration Laboratory (INPE/LIT) in issues that were considered for the development of a visualization software to allow the following of thermal-vacuum tests through the Internet.
