Methods, apparatus, systems and articles of manufacture are disclosed to determine a base station location. A disclosed example method includes identifying first signals comprising a same first signal identifier, identifying second signals comprising a same second signal identifier; identifying a first location associated with one of the first signals having a highest signal quality value and a second location associated with one of the second signals having a highest signal quality value; and determining that the first signals and the second signals are transmitted from a first base station if a distance between the first location and the second location satisfies a threshold.
