| Research Abstract |
In Japan there is GEONET, a vast network of about 1200 GPS-receivers. Based on the totalelectron content (TEC) from GEONET, we developed 3-dimensional tomography by usingthe least-squares fitting method with restrained condition. We also tried to combine TECdata from dual-band beacon (DBB) signal from LEO-satellites to the ground, but thedevelopment was not completed during the project term. On the other hand, wesuccessfully conducted dual-band beacon (DBB) experiment from JAXA sounding rocketS-520-26 to the ground.
