A system for tagging and tracking assets anywhere in the world under any environmental condition. Geo-Referencing Identification (GRID) tag, GRID satellite (GRIDSAT) tag and associated cloud infrastructure and user interface meet the objectives of a robust global tagging and tracking system. The GRID tag can be used to identify pieces of equipment or storage containers for low-value or aggregate equipment. GRID tags communicate with each other using a mesh radio in each tag. The GRIDSAT tag consists of a satellite modem, global positioning system (GPS) receiver, and mesh radio and can be used by itself for high-value items, large shipping containers, or vehicles and vessels to track and locate them, or used in concert with GRID tags that communicate with each other and with the GRIDSAT tag by means of mesh radio.
