Until now the number of satellites needed to obtain unique solutions to the GPS problem has only been conjectured.

At present, we can generally be sure of having contact to only four satellites.

With three or fewer satellites in the line of sight, GPS navigation definitely does not work.

With five or more satellites, the position of the receiver can be uniquely determined in almost all cases.
