There is nothing magical to GPS technology, 24 satellites orbiting at 55 degrees to the equatorial plane hammer the earth with precise radio pulses all day and night. These pulses are received by GPS receivers, and the location is derived based on the distance from the satellites.
However, not all location devices calling themselves GPS are really GPS. There is a technology called Assisted GPS (or sometimes AGPS) which is based on cell tower triangulation, having little if anything to do with GPS. Sometime also called “Location Based Servicing” (LBS) this uses proximity to cell towers to derive location. Since a minimum of three cell towers is required, it is not as accurate as true GPS. Some GPS motorcycle tracking devices being used now use the AGPS, since its cheaper for them and not necessarily going to give bike owners reliable help.
There are two advantages to LBS or AGPS, one is that its cheaper for the service provided and two the strength of the cell signal is stronger. However, if the device cannot pick up at least three cell towers, no location can be derived. Consequently, this technology works in more urban settings than in rural settings.
Once you have determined that you are dealing with a true GPS device, one has to determine which GPS Motorcycle Tracking is being used. Older GPS technologies require direct exposure to the horizon by either the device or an external antenna, which can make concealment a challenge. 3rd Generation GPS technology (SiRFStar III) works off of a reflective GPS signal. This means that the GPS device can be easily concealed without the need for the need for external antennas. This GPS Motorcycle Tracking technology can track inside garages and warehouses, where earlier generation GPS technologies could not.
