3D PLUS has developped in the framework of R&D activities an advanced CMOS camera for Space applications. The Centre National d'Etudes Spatiales (CNES), also called French space agency, is leading the developement of this camera, see Figure 1. This instrument has been integrated using the 3D PLUS technology [1] in order to be as compact as possible. Particular attention has been paid to ensure a good radiation tolerance to cover a wide range of scientific applications such as planetology, but also platform or launcher monitoring and star trackers
3D PLUS has developed in the framework of R&D activities a new high-performance and high-resolution CMOS camera head for space applications. With the collaboration of the Centre National d'Etudes Spatiales (CNES), also called French Space Agency, which is leading this development, the 12 Mpixels 3DCM800 Space Camera Head is integrated using 3D PLUS technology and expertise in designing high performances and high reliability electronics modules. This development intends to offer the best compromise for a highly miniaturized, highly reliable, all-in-one optoelectronic module solution for space applications. Particular attention has been paid to ensure radiation tolerance to cover a wide range of application such as planetology, equipment monitoring, in-flight spacecraft navigation and rendez-vous application, and earth observation applications. Technological developments were necessary to overcome challenges such as heat dissipation, and mechanical assembly of complex components, as will be presented in this paper.
Integrators ofCORBA-based dependable systems require information on the robustness of candidate middleware implementations, in order to select the implementation that is best suited to their requirements. We illustrate an approach for characterizing the dependability of middleware service implementations, with respect to corrupt method invocations arriving over the network. Preliminary results from experiments targeting the CORBA Event Service are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
