MAJOR PROGRAMME 1:International Monitoring System“The International Monitoring System shall comprise facilities for seismological monitoring,radionuclide monitoring including certified laboratories, hydroacoustic monitoring,infrasound monitoring, and respective means of communication, and shall be supportedby the International Data Centre of the Technical Secretariat.”(ARTICLE IV, PARAGRAPH 16)The year 2000 saw an important advancement of the International MonitoringSystem (IMS). The site survey programme, which determines whether stationlocations shown in the Treaty are suitable, is nearing completion. Installationswere completed at 27 additional stations, and the first 11 stations werecertified as meeting all PTS technical requirements. A major effort was made todevelop efficient procedures to connect stations to the data processing pipelineof the International Data Centre (IDC). From April 2000, the PTS assumed responsibilityfor routine station management, an activity that was previously carriedout by the prototype IDC (pIDC) in the United States of America. Considerableeffort was devoted to planning long term operation and maintenanceof IMS stations.IMS COMMISSIONINGAbrief summary of the status of the commissioning in each of the IMS technologies,giving the main highlights for 2000, is presented below. The statusof the site survey and station installation programmes at the end of 2000 issummarized in Tables 1 and 2.IMS Station Type Complete/ Under Way Contract Not StartedNot RequiredPendingTable 1.
