Abstract
YODA is a semi-automated data handling and analysis system for the PAMELA space experiment. The core of the routines have been developed to process a stream of raw data downlinked from the Resurs DK1 satellite (housing PAMELA) to the ground station in Moscow. Raw data consist of scientific data and engineering information. Housekeeping information are analyzed in a short time from download ( ≃ hours ) in order to monitor the status of the experiment and for the mission planning. A prototype for the data visualization runs on an APACHE TOMCAT web application server, providing an off-line analysis tool using a browser and part of code for the system maintenance. A quicklook system with GUI interface is used for operator monitoring and fast macrocommand issuing. On a longer timescale scientific data are analyzed, calibrations performed and the database adjourned. The data storage core is composed of CERN's ROOT files structure and MySQL as a relational database. YODA++ is currently being used in the integration and testing of ground PAMELA data.
