| Summary: | According to the propagation, GPS signal passes ionosphere and troposphere layer that influence its speed and direction. The changing of speed and direction of GPS signal influence the distance from satellite to receiver and cause mistake to coordinate produced by. With inverse problem GPS positioning technique then can be got level of bias on the two atmosphere layer and the both layer can be estimated its character with stochastic method that representatived with value of PWV (Precipitable Water Vapour) at troposphere and TEC (Total Electron Content) at ionosphere. By using realtime observation data of GPS at CORS station (Continuously Operating Reference Station) then can be made an automatization system with time based programming algorithm so it can estimate the character of troposphere and ionosphere layer in realtime in view of variety value PWV and TEC in temporal. Discussion will be aimed at realtime problem of GPS system development referred as and its mechanism and algorithm that starting by process of data acquisition, processing preparation, data processing, and visualisation result of data that have the value of PWV and TEC at realtime condition with all excess and weakness from result obtained. |
