A positioning device for determining the location of a vehicle stationary or moving on roads of a given network from positioning signals broadcasted by satellites of at least one constellation of satellites, comprising: a first unit determining a plurality of possible current positions and a plurality of time stamps, configured to: generate local replicas of positioning signals; receive, positioning signals broadcasted by one or more satellites in view; process, for each possible current position and time stamp, a correlation function between a received positioning signal and a local replica; a second unit: determining a common error to all the satellites, correcting the correlation results using the common error, determining, for each possible current position of the vehicle, multi-satellite likelihoods; determining a position and time stamp by comparing the multi-satellite likelihoods.
