Abstract

The disclosure provides a method and system for seamless tracking of an asset across indoor and outdoor environments by utilizing tags affixed on assets and anchor nodes deployed across a facility. Each anchor node emits heartbeat signals that are received by neighboring anchor nodes that comprise information pertaining to coordinates and timestamp of anchor nodes. A data acquisition module receives processed data from each tag to listen to heartbeat signals being shared. A tracking module determines live positional information of the asset based on data retrieved from the data acquisition module. The tracking module, by utilizing predictive positioning algorithms, detects an indoor location of each tag affixed on the asset using a UWB chipset and detects an outdoor location of each tag affixed on an asset using a GNSS chipset.

Dependent claims

A system for seamless tracking of an asset across an indoor environment and an outdoor environment, the system comprising:

a plurality of anchor nodes deployed across an indoor facility, wherein
each of the plurality of anchor nodes is configured to emit heartbeat signals,
the heartbeat signals from an anchor node of the plurality of anchor nodes are received by neighboring anchor nodes from the plurality of anchor nodes, and
the heartbeat signals comprise information pertaining to coordinates of corresponding anchor nodes of the plurality of anchor nodes;
a plurality of tags, each tag of the plurality of tags is affixed on an asset to be tracked, wherein each tag of the plurality of tags is configured to listen to the heartbeat signals being shared between the plurality of anchor nodes;
a data acquisition module configured to receive processed data from at least one of the plurality of tags;
and
a tracking module configured to:
determine live positional information of the asset based on data retrieved from the data acquisition module;
detect an indoor location of a tag of the plurality of tags affixed on an asset using a UWB chipset;
and
detect an outdoor location of the tag affixed on an asset using a Global Navigation Satellite System (GNSS) chipset.

A method for seamless tracking of an asset across an indoor environment and an outdoor environment, the asset being affixed with a tag and a plurality of anchor nodes being deployed across the indoor environment, the method comprising:

emitting heartbeat signals, by each anchor node of the plurality of anchor nodes, wherein
the heartbeat signals from an anchor node of the plurality of anchor nodes are received by neighboring anchor nodes of the plurality of anchor nodes, and
the heartbeat signals comprise information pertaining to coordinates of corresponding anchor nodes of the plurality of anchor nodes;
receiving processed data, by a data acquisition module from the tag, wherein the tag is configured to listen to the heartbeat signals being shared between the plurality of anchor nodes and to process the heartbeat signals to derive the coordinates based on data received from the plurality of anchor nodes;
and
determining live positional information of the asset, using a tracking module, based on data retrieved from the data acquisition module, wherein the tracking module detects an indoor location of the tag affixed on an asset using a UWB chipset and detects an outdoor location of the tag affixed on an asset using a Global Navigation Satellite System (GNSS) chipset.
