Abstract
In this paper, we outline the procedure used at the Royal Observatory of Belgium in order to compute the TEC using GPS measurements with a precision of 2–3 TECU. This procedure requires the determination of the so-called receiver and satellite differential group delays. The combined biases (receiver + satellite) are determined on a daily basis (i.e. one solution a day) using the geometry-free combination of code observations. The method is applied to a network of 7 permanently operating Turbo Rogue receivers; the reliability of these computed biases is discussed.
