Estimating the term…
The present invention relates to a method for determining the position of an electronic device (1) by means of satellites in a positioning system. In the method, satellite orbit data and a default position for the electronic device (1) are determined. In the method, at least the following steps are taken: a determination step for determining a first time data estimate by using said default position, a computing step for computing an estimate of the code phase of the satellite signal on the basis of said time data estimate, the default position and the satellite orbit data, and a searching step, in which a code-modulated signal transmitted by satellites of a positioning system is received for searching the signal of at least one satellite and for acquiring the signal by using said estimate of the code phase. The invention also relates to a system, in which the method is applied, as well as to an electronic device (1).
A method for determining the position of an electronic device by means of satellites in a positioning system, where satellite orbit data is determined and a default position is determined for the electronic device, wherein the method comprises at least:
A system with means for determining the position of an electronic device by means of code-modulated signals transmitted by satellites in a positioning system, in which positioning system satellite orbit data are determined, and which system comprises means for determining a default position for the electronic device, the electronic device comprising means for receiving code-modulated signals transmitted by satellites in the positioning system, wherein the system comprises:
An electronic device comprising means for determining the position by means of code-modulated signals transmitted by satellites in a positioning system, in which positioning system satellite orbit data are determined, and which electronic device comprises means for determining a default position for the electronic device, and means for receiving code-modulated signals transmitted by satellites in the positioning system, wherein the electronic device comprises:
