How Does a GPS Tracker Work? Understanding the Technology Behind Tracking Devices

Key Takeaways:

GPS trackers have become an integral part of modern technology, offering precise location tracking for various purposes. But how do these devices work, and what technology underpins their functionality? This article delves into the workings of GPS trackers, highlighting their operation, types, and applications._

Trilateration: The Core of GPS Tracking

GPS tracking operates by connecting to satellites, using a process known as trilateration. This method requires at least three satellites to accurately pinpoint the location of the GPS tracker, determining its elevation, latitude, and longitude. The GPS tracker measures the time it takes for radio signals to reach it from these satellites, allowing it to calculate its distance from each satellite.

The Inner Workings of a GPS Tracker

A standard GPS tracker consists of a GPS module to receive signals and calculate coordinates. For data loggers, large memory storage is essential to keep track of these coordinates. Data pushers, another common type of GPS tracker, include a modem (GSM/GPRS/CDMA/LTE) to transmit this information to a central computer, either via SMS or GPRS in the form of IP packets.

Types of GPS Trackers

1. Data Loggers: These devices log the position of the tracker at regular intervals in internal memory. They may feature a memory card slot or internal flash memory card and a USB port for data transfer.
2. Data Pushers: Widely used for asset, personal, and vehicle tracking, these devices send the tracker’s position and other information like speed or altitude to a designated server at regular intervals.
3. Data Pullers: Also known as GPS transponders, they are always on and can be queried as often as required. They are not as common as data pushers but are gaining popularity for certain applications.

Covert and Personal Tracking

Covert GPS trackers are designed to appear as everyday objects, making them ideal for scenarios like power tool protection, where they can be hidden and traced if theft occurs. Personal tracking devices are used in various situations, from monitoring race participants in sports to assisting in the care of the elderly and vulnerable, including those with dementia.

Applications in Asset and Animal Tracking

Asset tracking benefits greatly from GPS technology, with some devices being solar-powered to provide more frequent reporting due to their enhanced power capability. In the realm of animal tracking, GPS devices help scientists study activities and migration patterns of wild animals and are also used for domestic animal locations.

Legal Regulations and Compliance in GPS Tracking

Understanding the legal framework surrounding the use of GPS trackers is crucial both for manufacturers and users. Regulations differ significantly across countries and regions, impacting how these devices can be deployed and used.

GPS Tracker Laws in Different Countries

1. United States: The usage of GPS trackers by government authorities is subject to the 4th Amendment. In most cases, police require a search warrant. However, laws governing private citizen use vary, with states like California having specific statutes.
2. Australia: There are no federal laws specifically for GPS tracker surveillance. However, most states have statutes governing the use and restrictions of these devices.
3. United Kingdom: While no specific law addresses GPS trackers, several laws, including the Data Protection Act 1998, may affect their use as a surveillance tool.

Legal Implications of GPS Tracking

• Trespass: Deploying a tracker on another’s vehicle without consent may be considered a civil trespass in some jurisdictions.
• Stalking Laws: The use of GPS trackers can sometimes intersect with stalking regulations, as seen in the UK’s Protection of Freedoms Act 2012.
