WHAT IS SISNeTlab?
SISNeTlab is a new software tool that allows users to quickly and easily assess the performance of various SBAS systems. It gives the user awide variety of functionalities and the graphs produced can help in comparing and better understanding the various SBAS systems. The SISNeTlab project has been developed by ESA during the second half ofyear 2004. In February 2005, the beta version of the tool was launched, and the Tool was successfully tested. Since April 2005, the first version of the tool is available worldwide free of charge.Figure 1 puts the SISNeTlab tool in context. This tool is based on the ESA EGNOS Message Server (EMS), a 24h/24h archive of SBAS broadcast publicly available via FTP. SISNeTlab downloads the datacorresponding to the requested period from EMS, and performs various analyses on the information broadcast in the SBAS messages, presenting results in a graphical and easy to understand manner. This makesSISNeTlab a tool especially useful for the Educational community. Students can quickly learn about SBAS systems and understand the information broadcast by those.
