Track9 GPS tracking will calculate its location and transmit the concluded data to a server over the Internet using worldwide GPS , GSM cellular network and WiFi. That server hosts a platform that end users can access and view the device’s current and past historical path, speed and SOS alerts. All this data is then served via the internet and displayed on an end user device using a desktop app or to a smart phone using iPhone or Android app.
A GPS tracking system can benefit anyone. For business owners, it can be deployed to track the position of their fleet monitoring the behavior of employees. GPS systems are also helpful for small-time users as well. For example, families have used GPS devices to keep track of elderly, children or pets.
When selecting a GPS tracker, consumers will have to decide if they want an active real time or passive tracker. Passive trackers do not allow users to follow every move that a tracked person or object makes. The information must be obtained and then downloaded onto a computer. These types of trackers are usually more affordable, as they don’t require a monthly fee.
Active trackers, on the other hand, process and deliver data in every 10 seconds using a SIM and a GSM transceiver. Dispatchers receive real-time information via the GSM cellular network allowing them to closely monitor their assets or precious things. Nominal monthly fees are charged to pay for the cellular network services.
In case that the GPS satellite signal is blocked being indoor or by a structure, since there is no sky, not allowing for the GPS satellites signal to get through, the device is looking for cell tower signals and by cell tower signal strength triangulation trying to estimate rough location.
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 100 meters may be obtained in urban areas where mobile traffic and density of cellphone towers is sufficiently high. Rural and desolate areas which have less towers per square mile may see miles between base stations and therefore inaccurately determine locations often showing a location miles away from the device real location.
