1. Global Positioning System (GPS) functionality, which uses satellite signal jammers to determine location very accurately.
2. Connect to WiFi by tracking the router’s MAC ID. If Tracki GPS Tracker cannot find a GPS signal, it listens to all nearby WiFi routers and reports their MAC ID to our servers, which have access to a map of wifi blocker routers and their locations around the world. Accuracy is approximately 100-300 feet.
3. A less precise method is often called "cell tower triangulation," which refers to how cell towers calculate a tracker's geophysical location.
What is Cell Tower Triangulation?
In a perfect world, the GPS tracker's signal would be picked up by three or more cell towers, allowing triangulation to function. If you know the distance to a place from each of three unique points, you may compute the approximate position of that location in respect to the three reference points. We know the locations of the cell towers that receive our jammer GSM signal at Tracki because we have access to mapping of all cellular tower locations worldwide, and we can estimate the distance of the GPS tracker from each of those antenna towers based on the lag time between when the tower sends a ping to Tracki GPS tracker and receives the answering ping back.
In rare situations, a GPS tracker's signal may be received by more than three cell towers, providing for even greater precision. Because there are frequently many cell towers with overlapping signal coverage regions in big metropolitan urban areas, GPS tracker pinpointing accuracy is pretty good.
When the GPS tracker is not exposed to the open sky, such as when it is within a building or underground, and there are no Wi-Fi networks nearby, cell tower triangulation may be the only means to determine location if GPS signal is not accessible.
However, there are numerous areas with fewer cell towers available, such as on the outskirts of towns and in rural areas. When there are less than three cell towers accessible, locating a anti-tracking jammer device becomes significantly less precise. To have good coverage in cities with a lot more vertical structures that might be obstacles to GPS tracker transmitting and receiving, there must be a lot more cell towers spread. There are fewer cell towers in the countryside, and a GPS tracker's signal may be picked up by only one tower at a considerably longer distance.
Those places where the GPS tracker is only picked up by a single tower, and if it just has a single omnidirectional antenna, the accuracy is considerably worse.
Tracking accuracy in rural locations might range from 0.25 mile to several miles, depending on how many obstructions may be obstructing the tower's signal.
How does a GPS tracker work?
GPS, or global positioning system, uses 24 to 32 solar-powered satellites and ground stations to relay data to GPS-enabled devices.
The primary goal of GPS systems is to identify the exact location of an object or person in real time. The global navigation satellite system (GNSS) network is used by GPS tracking systems.
Each satellite in orbit transmits microwave signals to a receiver. The GPS tracker's receiver then utilizes these signals to compute your precise location from at least four GPS satellites. Finally, your location is calculated when the system triangulates your actual position on the earth based on these distances to the closest meters.
The method is based on a basic mathematical idea known as trilateration. GPS receivers use the exact location of at least four satellites and the distance between them to estimate four values: earth latitude, earth longitude, elevation, and time. The position of the receiver is determined by the position and distances to a certain satellite. The precise position of a satellite is regularly sent to all receivers within line of sight, which normally necessitates an unobstructed sky. The precise moment the satellite broadcast arrives at the receiver determines the distance to a satellite. The time created by each satellite's atomic clock is relayed at predetermined intervals by the satellite.
What a GPS Tracking Device Is and How It WorksGPS tracking devices operate on the same concept, but instead of displaying information on the device, the gadget's CPU calculates its location and transmits the resulting data to a server over the Internet via the international GSM cellular network. That server offers a platform from which end users may monitor the device's present and historical path, speed, and alarms. All of this data is then delivered over the internet and shown on a desktop software or a smart phone jammer utilizing an iPhone or Android app.
Anyone may profit from a GPS tracking device. It may be used by company owners to monitor fleets, staff conduct, and by households to keep track of elderly, children, or pets. To prevent their luggage from being lost or stolen, travelers embed a GPS tracker in it.
Active trackers, on the other hand, use a SIM and a GSM transceiver to process and send data in real time. Dispatchers receive real-time information via the GSM cellular network, allowing them to keep a close eye on their assets or valuables. Cellular network services are paid for with monthly fees.
In the event that the GPS satellites signal is obstructed due to being indoors or by a structure, and there is no sky, the device looks for cell tower signals and attempts to determine rough position using cell tower signal strength triangulation.
The GPS tracker determine where the device is located and roughly estimate the distance between the cellphone towers by interpolating signals between adjacent towers. A precision of down to 300 feet may be obtained in urban areas where density of cellphone towers is very high. Rural and county side areas which has less towers per square mile may see many miles between base stations and therefore inaccurately determine locations often showing a location miles away from the device real location.
For conclusion, when GPS satellite signal is available that is preferable to use. But in those cases when a GPS tracking device is blocked from open sky by structures, tall buildings, trees or even heavy clouds, cell tower approximation can mean the difference between knowing a general area whereabouts of GPS tracker or being in a complete dark.
