    摘要： Provided are architectures, systems, methods, and computer program products for real-time object locating and position determination using frequency channel diversity for transmitting and receiving position determination signals including bursts of location signals. Channelized frequency diversity of a short burst of small location signals that “hop” across multiple frequency channels is used to collectively produce a quasi-wideband position determination signal. Object tags operating with frequency channel diversity for transmitting location signals of position determination signals require low power consumption, but can still efficiently provide adequate position determination signals for reliable position determination.

    摘要： 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.
