The consumer electronics market was quick to offer remedies (radar detectors) to radar guns; a similar market may exist for devices to counter satellite tracking devices. Radio jamming of the relevant GPS or cell phone frequencies would be an option, as would a device which could detect the RF emissions of the GPS receiver circuitry. […]

In the US, the use of GPS trackers by police requires a search warrant, but use by a private citizen does not, as the Fourth Amendment does not limit the actions of private citizens. These devices can also raise concerns about personal privacy. Over time, the information collected could reveal a typical pattern of movements.

Data pullers


Contrary to a data pusher, that sends the position of the device at regular intervals (push technology), these devices are always-on and can be queried as often as required (pull technology). This technology is not in widespread use, but an example of this kind of device is a computer connected to the Internet and running […]

Data pushers


This is the kind of devices used by the security industry, which pushes (i.e. “sends”) the position of the device, at regular intervals, to a determined server, that can instantly analyze the data. These devices started to become popular and cheaper at the same time as mobile phones. The falling prices of the SMS services, […]

Data loggers


A GPS logger simply logs the position of the device at regular intervals in its internal memory. Modern GPS loggers have either a memory card slot, or internal flash memory and a USB port to act as a USB flash drive. This allows easy downloading of the data for further analysis in a computer. These […]

GPS tracking


A GPS tracking unit is a device that uses the Global Positioning System to determine the precise location of a vehicle, person, or other asset to which it is attached and to record the position of the asset at regular intervals. The recorded location data can be stored within the tracking unit, or it may […]

GPS drawing


GPS Drawing combines art, travelling (walking, flying and driving) and technology and is a method of drawing that uses GPS to create large-scale artwork.
