Abstract: Systems and methods for global positioning satellite (GPS)/global navigation satellite system (GNSS) based real time global asset tracking are described. In an embodiment provides a system for real time, fast, global asset tracking, the system includes: a server with a processor, a memory, and a network interface, wherein the memory includes a tracking application, where the tracking application directs the processor to: receive a message including specific data from a tag; determine a time search window based on the message received from the tag; perform an initial position search; perform calculations for position and time, utilizing the time search window, the initial position search and satellite ephemeris information; and display a position information of the tag.
