The development processes and the application achievements of space-borne microwave sounder pre-launch calibration technologies in China are introduced briefly. Then, the general project plan for pre-launchcalibration, the latest research achievements on the optimization and development of the microwave wide bandcalibration targets, emissivity measurement technologies and the system level uncertainty analysis of the laboratory, and the thermal/vacuum microwave sounder calibration system for "FY-3" meteorological satellite are reported, respectively. Finally, the key technological problems of the calibration technologies under researching are analyzedpredictively. © 2008 The Second Academy of China Aerospace Science & Industry Cooperation.
