This method implemented by a mobile device for obtaining its position comprises the steps of:
a. determining (E30) a current set of possible positions of said device from a measure of the distance between said device and an anchor device at a current instant;
b. determining (E50) a subsequent set of possible positions at a subsequent instant from said current set and from a vector of movement of said device at said current instant;
c. estimating (E60) the distance between said device and said anchor device at said subsequent instant
d. obtaining (E70) a new current set of possible positions of said device by selecting within said subsequent set of possible positions those which are at said distance from said anchor device
repeating steps b. to d. until said current set (AE1*) comprises only one element and estimating that the position of said device is said element. |
