The parameter of ionosphere that produces most of the effects on radio signals is total electron content (TEC). Ionospheric TEC variation with time can be viewed as a stationary random process under quiet conditions. This paper investigate the TEC covering the period from 8 November 2005 using Malaysia data for KTPK station. During this period with Kp, Dst, and Ap indices values of reported by the...
Multipath mitigation techniques using wavelet decomposition is proposed for extracting or modelling multipath from Global Positioning System (GPS) carrier phase observations. Multipath can be reduced by choosing sites without multipath reflectors or by using choke-ring antennas to mitigate the reflected signal. In this paper, we apply a method based on wavelets to decompose GPS double-differenced...
The ionosphere layer is very important to the communication system. This research involves the determination of total electron content (TEC) in ionosphere based on height in order to determine the appropriate TEC value for Malaysia and for the equitorial region generally. The ionospheric model used is the single layer model based on the Bernese GPS 5.0 Software. The ionosphere TEC map of Malaysia...
The difference in ionospheric delay between paths to the reference and mobile stations for differential GPS has been quantified for equatorial region. This small additional ionospheric error can be evaluated and predicted for the mobile station by means of a determined differential delay along the baseline so that accurate correction can be made for the most precise positioning. In this paper we studies...
