A GPS element industrial plant by reception fivefold satellite signals and conniving the receiver's position supported on trigonometry of the unlike signals. Accuracy is accrued beside all further outer sign that is accepted so the orbits of the satellites are set so that at record points on the earth there are at smallest 4 signals that can be standard.
