Abstract
Systems, methods, apparatuses, and computer readable media are disclosed for over-determining location estimations for an asset based on location estimates from a plurality of tags. Examples employ a spatial association model in a location system. Examples include a method for processing location information received from a radio frequency (RF) location tag. The method includes determining a first location of a first RF location tag associated with an asset, determining at least one second location of at least one second RF location tag associated with the asset, determining, using a processor, that the first location is not a valid location based at least in part on a comparison of the first location with the at least one second location using a spatial association model associated with the asset, and identifying the first location as erroneous in response to determining that the first location is not a valid location.
