Abstract:
A method of radio navigation among a plurality of stations S0, S1, . . . , Si, comprising the steps of:propagating a state of a first station S0 according to autonomous inertial measurements, wherein the state includes the position P0[x0,y0] of the first station, wherein x0 is the position of the first station along a first axis, and y0 is the position of the first station along a second axis orthogonal to the first axis; receiving a signal in the first station and resolving the received signal to at least one angular sector in a plane formed by the first axis x and the second axis y, the received signal comprising first information describing an estimated state of a second station S1, wherein the state includes a position P1[x1,y1] of the second station S1 and estimating the state of the first station S0 at least in part from the propagated state, the resolved angular sector, and the first information.
