GPS stands for global positioning system. The satellite-based navigation system consists of 24 orbiting satellites that transmit continuous signals to GPS receivers to determine the precise location of a vehicle, person or other asset it's attached to, and to record the position of the vehicle, person or asset at regular intervals.

The latitude and longitude of a GPS receiver can be determined by the position of at least three of the satellites.

Although GPS was originally developed for United States military purposes, it became available for consumer use, primarily as a navigational tool, in the mid-1980s.

    The GlobalPetFinder is a GPS tracking device for pets that incorporates cellular technology by sending a text message to your cell phone, PDA or e-mail address in order to let you know where your pet is.

    So, GPS is what tracks your pet and cellular technology is what transmits the pet's location to you. You can set up virtual boundaries — alerting you automatically via cell phone or email address when the pet crosses the boundary that has been previously determined.

    Or you may choose to use the device with no virtual boundaries. In this mode, you will only receive alerts when you request them. For example, say you're walking your dog and he gets away. You take out your cell phone and send a text message to 3-6-8-6-3 (F-O-U-N-D). In the body of the text message you type "Track Fido" (where Fido is your pet's name). You will then start receiving updated alerts about every three minutes that will provide you with your pet's location.

    The device comes with everything you need to get started: a snapguard (this securely attaches the device to the collar), a set of batteries and a battery charger. Similar to a cell phone, GlobalPetFinder contains a SIM card (this is what enables the device to communicate with your wireless device), which requires activation with a one-time fee of $34.99. MSRP: $289.99 plus $17.99 per month monitoring fee.
