. Data Processing System

  The SMILES ground data processing system consists of an Experiment Operating System (EOS) and Data Processing System (DPS). The EOS receives telemetry signals and sends commands. The DPS is divided into two main units; a data processing system for level 0 and level 1 (DPS-L0/L1) and the DPS-L2. Downlinked raw data from the SMILES will be received by the DPSL0/ L1 at the User Operation Area (UOA) at the Tsukuba Space Center (TKSC). The DPS-L0/L1 processes the raw data consisting of house keeping (HK) data and science data into level 1B data immediately. The level 1B data are periodically transfered via non-network media to a data server connected to the internet. The DPS-L2 located at the Institute of Space and Astronautical Science (ISAS) automatically receives the level 1B data from the data server through the internet and processes the level 1B data into level 2 data. The level 2 data are converted into the HDF-EOS format and are distributed to users accompanied with the ancillary data on the SMILES status through a web server.
