Abstract: The SuperAGILE (SA) instrument is an X-ray detector for Astrophysics measurements, part of the Italian AGILE satellite for X-Ray and gamma-ray astronomy launched on 23 April 2007 from India. SuperAGILE is now studying the sky in the 18 - 60 KeV energy band. It is detecting sources with advanced imaging and timing detection capabilities and good spectral detection capabilities. Several astrophysical sources have been detected and localized, including Crab, Vela and GX 301-2. The instrument can correctly resolve sources in a field of view of [-40, +40] degree intervals with an angular resolution of 6 arcmin and a spectral resolution of 8 keV. Transient events are regularly detected by SA with the aid of its temporal resolution (2 μs), signal coincidence on different portions of the instrument, and confirmation from other observatories. The SA scientific data-processing software running at the AGILE Ground Segment is divided into modules, grouped in a processing pipeline named SASOA. The processing steps can be summarized as data reduction, photonlist building, source extraction and source analysis. The software services allow orbital data processing (near real-time), daily dataset integration, Temporal Data Set (TDS) processing and TDS processing with source target optimization (TDS_SRC). Automatic data-processing monitoring and interactive data analysis is possible from an Internet-connected workstation with the use of SA data-processing Web services. Many solutions were implemented in order to achieve fault tolerance. Archive management and data storage are performed with the help of relational database instruments.
