Abstract

The earth’s ionosphere acts as a perturbing medium on satellite-based navigational systems like GPS. Variations in the ionosphere due to weather conditions caused by solar flares and coronal mass ejection can scatter Trans - Ionosphere radio signals producing fluctuations in both amplitude and phase and GPS cycle slips disrupting satellite communications and navigation. The ionosphere delay is one of the fundamental reasons for inaccuracy in GPS positioning and routing. The Total Electron Content (TEC) along the radio wave path from a GPS satellite to the ground receiver is directly proportional to the ionosphere delay. This paper proposes a method allowing to calculate the TEC with a correctness of about 2–3 TECU and to sense Travelling Ionosphere Disturbances using GPS measurements.
