The location and time of the signal’s transmission are contained in the signals that these satellites continuously send out. The location of a tracking device is determined by the GPS receiver, which receives signals from several satellites and measures the time it takes for the signals to reach the receiver. The great accuracy of GPS tracking is one of its benefits. Generally, location data from GPS devices can be obtained with a few-meter accuracy. Because of this, GPS tracking is perfect for applications like navigation systems and emergency services where precise location information is needed.
GPS tracking is not without its limitations, though. Physical barriers such as dense foliage or tall buildings can block GPS signals. In these situations, there’s a chance that GPS tracking precision will decrease or the device may completely lose signal. Also, GPS tracking devices might not function properly indoors or underground because they need a direct line of sight to the sky in order to receive signals from satellites. Mobile devices that track objects or people make use of cellular networks to locate them.
For the purpose of triangulating their position, these devices speak with adjacent cell towers. A cellular tracking device searches for nearby cell towers and determines each tower’s signal strength when it is turned on. The device can determine how far away from each tower it is by comparing the signal strengths of several towers.
The device determines its location by triangulating its position based on the separations between multiple towers. Being able to operate in locations where GPS signals might be blocked is one benefit of cellular tracking. Since cellular networks cover a larger area than GPS satellites, cellular tracking devices can provide location data indoors and in urban settings with tall buildings.
Cellular tracking does, however, have certain drawbacks. Cell tower densities in a particular area can have a significant impact on the accuracy of cellular tracking. Cellular tracking accuracy may be lower in rural or isolated areas with fewer cell towers. Also, since cellular tracking devices rely on a cellular network connection to pinpoint their location, they might not function properly in places with spotty or nonexistent coverage. RFID tracking devices use radio waves to pinpoint a person or object’s location.
The components of these devices are a tag or chip that is affixed to the object being monitored & a reader that communicates with the tag through radio waves. When a reader emits radio waves, any nearby RFID tag or chip takes up that energy and utilizes it to power itself. After that, the tag replies to the reader by sending a special code or other data. The reader locates the tagged object by using the response from the tag that it has received.
RFID tracking has the benefit of being able to track several objects at once. Numerous things, including inventory items, cars, and even livestock, can have RFID tags attached to them. RFID tracking is perfect for applications where a large number of objects need to be tracked because the reader can scan multiple tags at once.
But there are drawbacks to RFID tracking as well. Since RFID tracking typically has a range of only a few meters, objects must be close to the reader in order to be tracked.
