Asset tracking using alternative sources of position fix data
First Claim
Patent Images
1. A computer-implemented method, comprising:
- receiving input indicating that a first asset has been loaded onto a conveyance;
determining that a first tag coupled to the first asset is unable to transmit tag position fix data describing a position of the first asset with a signal strength that satisfies a threshold;
receiving alternative position fix data from an alternative source associated with the conveyance, the alternative position fix data describing a particular position at a given time; and
associating the alternative position fix data with the position of the first asset at the given time.

Abstract
Techniques for tracking physical assets are described. In one aspect, input indicating that an asset has been loaded on a conveyance is received. When a tag attached to the asset is unable to transmit position fix data describing a location of the asset to a server, alternative position fix data (e.g., from the conveyance or another tag coupled to another asset on the conveyance) is used to indicate the position of the asset and tag. In another aspect, a relay component is used to receive the tag position fix data from the tag and forward it to the server.
