Systems and methods for locating telecommunication cell sites in accordance with embodiments of the invention are illustrated. One embodiment includes a method for locating cell sites, including obtaining a plurality of observations, where each observation includes a timestamp, a coordinate, an active record, and a set of passive records, uniquely identifying secondary cell sites in the passive records by cross-matching active records from a first observation with passive records from a second observation, annotating the observations with unique identifiers for each secondary cell site, time-smoothing the received signal strength values, estimating the distance from each observation to the primary cell site and secondary cell sites associated with the observation by providing a machine learning model with at least the time-smoothed signal strength values and the plurality of annotated observations, and locating the primary cell sites based on the estimated distances.
