Abstract :
This paper presents a statistical study of ionospheric small- scale structures detected at the GPS station of Brussels (BRUS) from 1994 to 2008. Two types of structures have been detected: Travelling Ionospheric Disturbances (TID\´s) and so- called "Noise-Like Structures" due to geomagnetic storms. The influence of such structures on differential positioning like Real-Time Kinematic (RTK) have been explored: the positioning error due to the ionosphere is larger during geomagnetic storms than during the occurrence of TID\´s. Maximum values observed for a baseline of 11 km are respectively 65 cm and 15 cm.
