The governments of the world have built thousands of low-powered radio transmitters called beacons. All navigational charts have the beacons' positions marked on them, as well as the frequencies they operate at.
Let us say you are flying an airplane in North Carolina, and there is a beacon in Fayetteville, one in Lumberton and one in Dunn. (This is an example; I know there are beacons in Fayetteville and Lumberton because there are airports there, but am not sure about Dunn.) If the beacon in Fayetteville transmits at 140MHz, the one in Lumberton transmits at 141MHz and the one in Dunn transmits at 142MHz, the radio direction finder in your plane can measure the angles those three frequencies are coming in at and, from that information, calculate where you are.
