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. ## Claims ### Claim 1 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;
