Abstract
A method for sensor operation includes deploying a network of sensors (22), which have respective clocks (36) that are not mutually synchronized. At least a group of the sensors receive respective signals emitted from each of a plurality of sources (24, 26), and record respective times of arrival of the signals at the sensors according to the respective clocks. Location information is provided, including respective sensor locations of the sensors. The respective clocks are synchronized based on the recorded times of arrival and on the location information. In the process the sources may be localized, or if the sources are far away, then their directions may be resolved. Sensor positions may also be resolved in the process.
