Abstract
The invention relates to a method for positioning a receiver receiving code modulated signals transmitted by satellites and formed by an individual code for each satellite. In order to provide a reliable reference position for the receiver, it is proposed that in a first step, a reference position for said receiver is calculated based on frequency measurements of said code modulated signals. This reference position can then be employed in a second step for determining the accurate position of the receiver. The invention equally relates to such a receiver, to positioning means, to a computing server and to a positioning system comprising means for realizing the proposed method.
