The Workflow-Based Modelling Method for Spacecraft Automatic Testing Process

Nowadays workflow technology becomes more and more popular, which simplifies the application development and maintenance work, therefore enhancing efficiency. The process of spacecraft testing is very complex, and still depends on manual work to a large extend, so this paper introduces workflow theory into spacecraft testing area which brings forward a new opening architecture and helps to reso...

GRANAT / SIGMA observation of the early afterglow fromGRB 920723

We present a GRANAT/SIGMA observation of the soft gamma-ray afterglow immediately after GRB 920723. The main burst is very bright. After 6 s, the burst light curve makes a smooth transition into an af-terglow where ux decays as t ?0:7. The power-law decay lasts for at least 1000 s; beyond this time, the afterglow emission is lost in the background uctuations. At least 20% of main burst energy i...

Automatic Reconstruction of Spacecraft 3D Shape from Imagery

We describe a system that computes the three-dimensional (3D) shape of a spacecraft from a sequence of uncalibrated, two-dimensional images. While the mathematics of multi-view geometry is well understood, building a system that accurately recovers 3D shape from real imagery remains an art. A novel aspect of our approach is the combination of algorithms from computer vision, photogrammetry, and...

Automatic Vision-Based Monitoring of the Spacecraft Docking Approach with the International Space Station

The software package which allows to automate the visual monitoring of the spacecraft docking approach with the international space station is being considered. The initial data for this complex is the video signal received from the TV-camera, mounted on the spacecraft board. The offered algorithms of this video signal processing in real time allow to restore the basic characteristics of the sp...

The Design and Implementation of Workflow Engine for Spacecraft Automatic Testing

Spacecraft software automatic testing plays an essential role in spacecraft testing field for a decade. However, less attention has been paid on it based on workflow methodology. In this paper we introduce workflow technology into testing for improving the automation of spacecraft software testing. Firstly we present a spacecraft testing process definition language STPDL. Then workflow patterns...
