 note = {Usually, three kinds of variation components with different spatial scales are identified in the ionosphere: the large scale component which is fixed in the solar-geomagnetic reference frame with scale from several thousands to dozens thousands kilometers; the medium scale, 400 to 1,400 km, components, the evolution process of northward intense TEC enhancement and the pre-noon rapid irregular fluctuations along the low latitude area of geomagnetic reference frame can be easily identified; the short scale traveling ionospheric disturbance (SSTID) of scales of 140 to 400 km, and of 30 to 140 km, appears every day. All of them will introduce the extra parts into the s/c tracking and orbiting, i.e. Doppler or ranging. A GPS method is developed and applied to monitor these variations over Japan Islands, and the effects of them on s/c tracking is considered., 資料番号: AA0045441069},
