This systemwill be developed in the Earth Observation Center (EOC) of JAXA with the function for Ka band data receptionand X band data reception. The system consists of Data Receiving Subsystem, Data Recording Subsystem, DataProcessing Subsystem, and Mission Operation Management Subsystem, etc.b) ALOS Information SystemThe ALOS Information System provides the archive, catalog searching, and online data distribution functionswhich will be installed at EOC by JAXA. The system also provides LAN within EOC and network connectionswith external agencies. The system consists of ALOS Central Information Subsystem, which is the system incharge of data archive and management, ALOS User Service Subsystem, which is the system in charge of data4-1
