In traffic, vehicle safety generally depends on the relative separation between two vehicles, and not at all on their absolute geographical positions. Therefore, methods are disclosed for determining the relative separation differentially. Two vehicles simultaneously acquire the same satellite signals, reduce the signals to data, and then transmit the data, preferably with fast 5G or 6G, to one of the vehicles or to a roadside access point. A computer then analyzes the data based on differences between the two sets of signals, thereby determining the separation distance and angle between the two vehicles. Other vehicles within range can do the same. The relative locations of all the participating vehicles can then be broadcast, in the form of a table or a map, to all the vehicles in proximity. Improved position measurements can enable collision avoidance and harm minimization in traffic.
