What is a GPS Tracking System?
A GPS tracking system communicates with GPS satellites to showcase the tracker’s location. GPS receivers can be used anywhere on Earth and, with the right software, can show their location to a smartphone, another tracker, or a navigation system.
The Fundamentals of GPS Technology
GPS tracking works by connecting to satellites to send their location through a process known as trilateration. Trilateration uses at least three satellites to pinpoint the location of the GPS tracker by measuring its elevation, latitude, and longitude.
The global navigation satellite system operates 24/7, ensuring that GPS trackers can provide real-time location information at any time.
Depending on the type of GPS tracker, these devices can keep a log of locations or send locations only when requested. An active GPS tracker will allow a user to see the tracker’s location in real-time. Passive trackers take the data and keep it for the user to look at later.
Introduction to A-GPS: Definition & Importance
A-GPS stands for assisted GPS and it’s a newer version of GPS software. A-GPS uses the satellites of standard GPS and combines that information with cell phone towers and/or Wi-Fi networks. Using these sources simultaneously allows for a more accurate GPS location to be shared.
A-GPS is important because it makes it easier to communicate between tracking systems and satellites when they don’t have a direct path between them. Satellites work hard to give accurate location information, but cell phone towers and Wi-Fi networks help where the satellites fall short. This can allow for better location information in more areas of the United States.
How Does a GPS Tracker Work?
The tracking unit in a GPS tracker is a sophisticated piece of technology. It houses a receiver that captures signals from at least four satellites. By analyzing the time it takes for these signals to reach the device, along with their precise coordinates in space, the tracking unit calculates its exact location on Earth. This data is then sent to the user’s device or a central server, allowing you to monitor and track the device’s movements in real time.
GPS trackers send their location information to a smartphone through an app or a website. When the information is sent can vary based on the type of GPS tracker being used. The most common times a tracker sends locations include:
- Times set by the user, such as every hour
- When a user requests the information through the app or dashboard
- When the person with the tracker sends their location
- When the tracker crosses a geofence
In contrast, Bluetooth trackers don’t need to connect with satellites and are better suited for finding lost items within a close range. While both GPS and Bluetooth trackers serve tracking purposes, understanding how they work and their respective capabilities can help you choose the right one for your needs.
Defining a Geofence
A geofence is a virtual fence that can be set through GPS tracker software. The user can create a boundary on the map in the tracker’s app. Then, the GPS tracker will send a notification to the user’s mobile phone if the tracker goes past the geofence’s location. While it’s not a fence in the literal sense, it can give parents peace of mind knowing their kid is within the allotted location.
How are GPS Trackers Used?
GPS trackers are devices that can be used in a variety of ways. Companies and individuals alike can tailor their use to meet specific needs.
Let’s look at three of the most common GPS tracker uses.
- Personal Tracking: Individuals can use GPS trackers to keep an eye on their personal belongings or even family members. A GPS tracker like the Findmykids app can provide a parent peace of mind that their child made it to school safely. Dog owners can check in and ensure their dog is in their yard while no one’s home to watch them. Trackers can even be put in backpacks, purses, or keys so the user can locate their lost items.
- Fleet Management: Companies often find GPS trackers useful for keeping an eye on their fleet. These trackers can provide simple fleet management by sending real-time locations of the company’s vehicles. With more advanced trackers, users can get information about routes taken to create more efficient routes for their employees. These changes can save money and time, offsetting the cost of installing the trackers.
- Asset Tracking: Theft prevention is another common use of GPS trackers. Trackers can be placed on boats parked on the lake or lawnmowers to cut the neighborhood’s grass. Ensuring valuables are where they are meant to be can allow any user extra peace of mind when loaning out equipment or docking their boat after a long weekend.
Potential Limitations and Risks of GPS Trackers
GPS trackers are a wonderful use of technology but, as with anything, there are some potential downsides to keep in mind.
1. Possibility of Undetected Tracking
Since GPS trackers are often small and easy to place in bags or cars, it’s entirely possible that someone can track another person without them knowing. This is enough of a concern that some GPS tracker manufacturers have created alerts if an unknown tracker is nearby. If someone is concerned they are being followed, checking for unrecognized GPS trackers would be a good starting point.
2. Potential Inaccuracies in GPS Tracking
GPS trackers try to give accurate information, but their largest risk is giving inaccurate locations. Most often the issue is due to one of these common problems:
- The tracker has only GPS, not A-GPS
- The A-GPS tracker isn’t near cell phone towers or WiFi signals
- The tracking device is surrounded by tall buildings or heavily wooded areas
- The app is experiencing mapping errors
- The tracker is inside a building or even underground
It’s also important to note that even the most accurate GPS trackers can be off by as much as sixteen feet.
3. Concerns Over Location Data Access
As with many other items used online, GPS tracking devices can be hacked. If this happens, an unauthorized user can see the tracker’s location information, which can lead to a host of safety concerns.
Fortunately, it’s unlikely that a tracker will be hacked. Users should utilize security options like two-factor authentication and strong passwords to lower the chances even more. It’s also a good idea to not check the tracker’s app on a public Wi-Fi network to keep the information inside secure.
4. Subscription Costs Associated with Some Trackers
While some GPS trackers only require the initial purchase cost to get the best experience, users will often have to pay monthly fees. Depending on the tracker chosen, monthly subscription rates can be as high as $40 monthly. Users should shop and compare prices and features to pick the best tracker.
5. School Policies Regarding GPS Tracking Devices
Many GPS-enabled devices are easy to hide in backpacks. Using this form of tracker is acceptable at most schools. However, some parents may choose a smartwatch for their child as their GPS tracker, which may have games downloaded on them. These additions may cause distractions.
It’s best to check the school’s handbook or talk to an administrator before sending a child to school with any GPS tracker to be safe.
Types of GPS Trackers and Their Advantages

GPS trackers play a pivotal role in modern tracking and navigation systems. They operate by connecting to special satellite signals, allowing us to pinpoint locations with remarkable accuracy. Whether it’s for personal safety, asset protection, or navigation assistance, the ability of GPS trackers to connect to these special satellite signals has revolutionized the way we track and monitor our world.
Can a cell phone detect a GPS tracker?
Most cell phones aren’t designed to detect GPS trackers out of the box. However, there are apps available for download that can notify the user of nearby location trackers using either Wi-Fi or Bluetooth.
Do GPS trackers work without cell service?
If the GPS tracker has A-GPS technology, it can work without cell service if it has access to satellites or WiFi signals. Standard GPS technology doesn’t utilize cell service at all, so it can work if it has access to the satellites needed.
How far can a GPS tracker work?
The range of the GPS tracker is dependent on the device. However, most trackers can work anywhere within the range of satellites (or cell phone towers and Wi-Fi for A-GPS). With access to these signals, there is no limit to the range.
How does GPS tracking work without the Internet?
Without Internet access, GPS trackers will utilize special satellite signals to track and send locations. Some trackers will store this information for users to view later if the app user is somewhere without Internet access.
