Method for performing positioning and an electronic device

A positioning system which comprises at least positioning means (S, MS) and a receiver (MS) comprising means (1, 2a-2d) for receiving a code modulated signal transmitted by satellites (SV1-SV4), the code modulated signal being formed by an individual code for each satellite (SV1-SV4), characterized in that the positioning means (S, MS) also comprises means (S, 10, 11) for receiving position data on at least one selected reference point (BS) whose position is substantially known, means (S, 10, 11) for receiving position information of the satellites (SV1-SV4), and means (S, 3) for determining the position of the receiver on the basis of at least the position information and the position of said at least one reference point (BS), and the position of said reference point (BS) is used as the default position of the receiver (MS).

An electronic device (MS) which is arranged to be used in a positioning system with positioning means, and which electronic device also comprises at least means (1, 2a-2d) for receiving a code modulated signal transmitted by satellites (SV1-SV4), the code modulated signal being formed with an individual code for each satellite (SV1-SV4), the code modulated signal being formed with an individual code for each satellite (SV1-SV4), characterized in that the electronic device (MS) also comprises means (10, 11) for determining the number (Nchipk)and code phase (Δchipk) of chips received after a change in the code sequence preceding the moment of positioning on the basis of said reference code, and means for transmitting the chip number data and the code phase data to said positioning means, wherein the positioning means also comprise means for receiving position data of at least one selected reference point whose position is substantially known, means for receiving position information of the satellites, and means for positioning the receiver on the basis of at least said position information of the satellites and the position of said at least one reference point, and the position of said reference point (BS) is used as the default position of the receiver (MS).

A computing server (S) comprising at least positioning means (S, MS) for positioning a receiver (MS), the receiver (MS) comprising means (1, 2a-2d) for receiving a code modulated signal transmitted by satellites (SV1-SV4), the code modulated signal being formed with an individual code for each satellite (SV1-SV4), characterized in that the positioning means (S, MS) also comprise means (S, 10, 11) for receiving the position data of at least one selected reference point (BS) whose position is substantially known, means (S, 10, 11) for receiving position information on the satellites (SV1-SV4), and means (S, 3) for positioning the receiver on the basis of at least said position information and the position of said at least one reference point (BS), and the position of said by reference point (BS) is used as the default position of the receiver (MS).
