1. A method for detecting locations of navigation interfering devices comprising: receiving a plurality of navigation signal parameter datasets each from one of a plurality of satellite signal receivers; detecting at least one interference event data according to an interference analysis of at least some of said plurality of navigation signal parameter datasets; updating a plurality of probability values, each for one of a plurality of suspected navigation interference device locations by a location analysis of said at least one interference event data, wherein each one of said plurality of probability values is indicative of a likelihood that said at least one interference event data originates from some of said plurality of suspected navigation interference device locations; selecting a subset of said plurality of suspected navigation interference device locations according to said plurality of probability values; and outputting said subset.
