Security Concepts has announced the Worldtracker sms, a tiny GPS tracking device powered by the Sirfstar III chipset with WAAS. Worldtracker SMS is able to track vehicles, packages, people or anything else you can imagine and location information can be reported to a cell phone or PDA using SMS messages send by it’s Tri Band GSM module (GSM850/1800/1900 MHz or GSM900/1800/1900 MHz). It can also visualize the tracking data using Google Earth. It has a battery life of 24 hours, however by using an additional battery pack it can run for almost four days.
