Abstract:	This paper presents a selecting algorithm of combination of positioning satellites to be corrected in real time in Centimeter Level Augmentation Service utilizing four-satellite constellation of Quasi-Zenith Satellite System. On offline, time series of the combination at each epoch of broadcast is planned with criterion on the PDOP of the selected satellites. In real time, the combination is determined based on the plan and can be modified in a reflection of integrity information of the satellites. The validity of the algorithm in terms of statistics of the number of corrected satellites and DOP of the satellites in each location of Japan is shown in a numerical simulation.
