A computer-implemented method of geolocating a target includes: receiving, from a plurality of sources, a corresponding plurality of angle estimates of the target relative to the respective sources; generating a corresponding plurality of planar renditions of the received angle estimates; selecting a combination of two or more planar renditions whose intersection defines a polygon; in response to multiple such combinations, selecting one having a largest number of planar renditions; and determining a center of the polygon of the selected combination. A computer-implemented method of evaluating geolocation geometry with respect to a target includes: geolocating the target from received sensor data of the target from multiple sources and location data of the sources; generating entries of a covariance matrix from the location data and the geolocation; deriving eigenvalues of the covariance matrix from the generated entries; and comparing the derived eigenvalues to evaluate the geolocation geometry with respect to the target.
