The direct and indirect methods for predicting the ionospheric total electron content (TEC) by using the ARIMA ( p , d , q ) model in the theory of time-series analysis are proposed. The direct method predicts directly the time series composed of the

The radio wave used in communications at distance and navigation by satellite is affected by the ionosphere. Therefore the study on the total electron content (TEC) in the ionosphere is very important. There are some prediction models of the ionosphe

Applying recent 10-year GPS measurement data from some nationwide GPS networks, several regional GPS monitoring networks and the Asia-Pacific Regional Geodetic Project (APRGP), this paper gives out a combined, consistent and unified velocity field so

Using the pseudo-nonfiducial method of regional net, we have treated the GPS data of APRGP97, APRGP98 and APRGP99 by means of GIPSY software. The precision of coordinates obtained by us for most sites is 1-2 mm for north-south component and 2-5 mm fo

In this paper, we have used a square root formulation of the Wheeler-De Witt equation to quantize a minisuperspace model consisting of the Bianchi-I type universe with a radiation field source. We have derived a wavefunction with a conserved current

By analyzing daily continuous data of Chinese Global Positioning System (GPS) fiducial network with 25 sites from 1999 to 2001, seasonal altitude variations with amplitude of 3-10 mm are detected. Most part of the variations can be explained by the s
