Method for positioning a to-be-positioned device
A method for positioning a device includes the steps of: estimating an absolute distance between a reference point and the device at each of a current time point and a number (N) of consecutive previous time points, where N is a integer smaller than n, n is a non-negative integer indicating a total...

| description | A method for positioning a device includes the steps of: estimating an absolute distance between a reference point and the device at each of a current time point and a number (N) of consecutive previous time points, where N is a integer smaller than n, n is a non-negative integer indicating a total number of time points since the device starting to move, and the current time point is defined as the (n)th time point; estimating a unit vector of a movement direction of the device in each of (n−N+1)th to (n)th time periods; and estimating a coordinate of a location of the device at (n)th time point based on the absolute distance(s), the unit vector(s), and a coordinate of a location of the device at each of the number (N) of the consecutive previous time points. |
