GPS Forensics for Counter Terrorism and Law Enforcement Agencies
A relatively new handheld electronic device that is often seen in the public domain is called the GPS navigation receiver. This type of device is used in cars, trucks, airplanes, boats, and can also be used by pedestrians. These devices contain maps. The GPS device collects a series of signals from various orbiting sattelites and then triangulates them. The result is that the location of the GPS receiver is shown on the map.
Let us consider a real example that I tested. On the Garmin Nuvi 1300 receiver, there is a small onscreen icon that indicates the location and speed of the driver. This GPS device contains a two gigabyte drive that uses a FAT 32 file system and appears as a flash drive when it is connected to a Microsoft Windows based computer. A person can use a mini USB cable to connect the Nuvi 1300 to the laptop or desktop computer.
