Zusammenfassung:Systems and methods for wireless downhole positioning are provided. The method can include synchronizing a first clock with a second clock; wherein the first clock is disposed in a first 5 transmitter, Wherein the first transmitter is disposed at a known location, and wherein the second clock is disposed in a downhole tool. The method can further include disposing the downhole tool into a wellbore; wherein the downhole tool comprises a first receiver; transmitting a first wireless signal from the first transmitter along the wellbore at first time; receiving the first wireless signal via the first receiver at a second time; determining a first elapsed time between 10 the first time and the second time; and determining a first downhole position of the downhole tool based on the first elapsed time.
