Security Concepts launches the world's smallest real-time GPS tracker, featuring the latest in 3D mapping technology from Google Earth.

WorldTracker SMS is equipped with a SiRF-StarIII chipset and a Siemens MC-46 tri-band GSM module, the unit measures just 2.56 by 1.7 by 1.1 inches (45 by 66 by 25 millimeters) and weighs a mere 3.1 ounces (87 grams). The device is completely self contained and features built in GPS and GSM antennas, as well as a rechargeable Lithium Ion battery. It is small enough to place on a belt or in a purse, hide inside of a vehicle, or easily integrate into machinery.

WorldTracker SMS features a WASS enabled GPS receiver, allowing the unit to function indoors, in canyons, and through metal. The Federal Aviation Administration (FAA) and the Department of Transportation (DOT) developed the WAAS program for use in precision flight approaches. WAAS boosts GPS signal integrity and corrects for errors caused by atmospheric disturbances, timing, and satellite orbit errors. A WAAS-capable receiver will give you a position accuracy of better than three meters 95 percent of the time.

The WorldTracker SMS works world-wide thanks to its support of the three major GSM frequency bands: 900/1800 MHz worldwide and 1900 MHz in the U.S
The WorldTracker SMS is designed to send short message service (SMS) messages containing location and status information. With its geofencing ability, users can define an area and set the unit in park mode. If the unit moves beyond its predefined limits, it will automatically send an alert message with its current location. The unit also features an emergency button, which a carrier can use to alert others in the event of an event such as a kidnapping.

Security Concepts www.trackingtheworld.com offers complete service for a monthly fee. Users can use Google Earth, which combines satellite imagery, 3D maps and the power of Google search to create a complete virtual earth. By using Google Earth, users eliminate the need to update separate mapping software and pay monthly licensing and maintenance fees for mapping software.
