「Eyes from Above 一The New Era」Press Conference    
NSPO / 2004/09/23

After its successful launch on May 21, 2004, FROMOSAT-2 circled around the earth 14 times daily with global coverage. Since June 2004, it has successfully captured images of the northern, central, southern, and eastern part of Taiwan and the offshore islands. These images are then stored in the database. When natural disasters occurred, FORMOSAT-2 has also provided satellite images for damage evaluation and investigation. From mid of August, FORMOSAT-2 has commenced a project that involves capturing images of the entire globe. From countries such as South Korea and Philippines in the first orbit to countries such as Japan and Australia in the fourteenth orbit, ROCSAT-2 has captured images of major cities in Asia, Europe, America, and the Pacific region. These cities include Taipei, Seoul, Beijing, Lhasa, Baghdad, Athens, Paris, Ottawa, New York, Belmopan, Honolulu, and etc. The FORMOSAT-2 mission operation team continues to evaluate the scheduling accuracy and to assign the image capturing areas for the purpose of Remote Sensing Instrument functional testing and Image Processing System parameter calibration.

The image quality of FORMOSAT-2 is world-class. The global images captured by FORMOSAT-2 are ready to be distributed worldwide. The NSPO is planning to share FORMOSAT'2 “Eyes from above” images with agencies throughout the world by establishing international collaborations.

FORMOSAT-3 is a low earth orbit satellite constellation composed of six micro satellites. These micro satellites are used to receive signals transmitted by the 24 US global positioning satellites (GPS) for the purpose of observing the earth's atmosphere and ionosphere. The data received by the six micro satellites can be used for studying changes in weather, climate, and ionosphere and for land measurement study. These data are also useful for increasing the accuracy of climate and space weather forecasts.

Most of the hurricanes are developed over the ocean and majority of the hurricane pathways is on water. Since the current hurricane measuring data is limited to land areas, it is difficult to obtain hurricane information data on sea. FORMOSAT-3 can provide approximately 2,500 daily data points on reflection incidents through the atmosphere. These reflection incidents are evenly distributed among the atmosphere, and each incident data point can provide vertical distribution information of the atmosphere. These data points are extremely important for the regional and global weather forecasts. Since the accuracy of the data measured by FORMOSAT-3 is significantly higher than other measuring method and is not affected by the changes and aging of measuring instruments, these data points can be used for observing the micro and long-term changes of the global climate.

Currently, there are several satellites using GPS technology to make measurements of the atmosphere, such as CHAMP of Germany, GRACE of US and Germany, and SAC-C of Argentina. However, these are single satellite. Therefore, the data measured by these satellites are limited. In the future, FORMOSAT-3 can provide more condensed and more evenly distributed observation data that will include sea regions where currently no established ground receiving facility. As a result, FORMOSAT-3 can have better tracking of the hurricane movements in the Taiwan vicinity and provide more accurate alerts for thundershowers.

FORMOSAT-3 is a collaborative project funded and developed by both Taiwan and US. FORMOSAT-3 is also the first ever economical and fast measurement method that used to calculate the instant changes in the global atmosphere and ionosphere. In the future, FORMOSAT-3 can and will significantly improve the accuracy of weather forecast over Taiwan's surround sea region. Such improvement will bring the new era in the weather forecast for Taiwan and for the entire world.
