A disposable GPS tracker with a 3-year lifespan can work stably for a long time without battery replacement, relying on its unique design and technology. Its working principle mainly focuses on low power consumption, efficient positioning and communication.
In terms of hardware, such trackers adopt ultra – low power consumption chips and components. The GPS module is a model specially designed for low – power scenarios. It stays in a dormant state when not performing positioning operations and only wakes up briefly when it needs to obtain location information, minimizing power consumption. The battery uses a high – capacity lithium thionyl chloride battery, which has a high energy density and an extremely low self – discharge rate. It can provide continuous power supply for the device for up to three years and is suitable for one – time use scenarios.
In terms of positioning and communication mechanisms, it usually adopts an intermittent working mode. The device will start the GPS positioning function at preset time intervals (such as every hour or every half a day), quickly capture satellite signals and calculate the current position. After positioning, the location data is sent to the background server through low – power wireless communication technologies (such as LoRa, NB – IoT, etc.). These communication technologies consume little power when transmitting data and can achieve data transmission over long distances, avoiding power loss caused by frequent communication.
In addition, the tracker also has an intelligent power management function. When the device is in an environment with weak signals, it will shorten the attempt time for positioning and communication to avoid wasting power due to long – term signal search. At the same time, it will automatically adjust the working frequency according to the usage scenario. For example, it will reduce the positioning frequency when the asset is stationary and appropriately increase it when it is moving, so as to balance positioning accuracy and power consumption.
Through the combination of the above hardware selection, working mode design and intelligent power consumption control, the disposable GPS tracker with a 3-year lifespan can work stably for a long time, meeting the needs of long – term tracking of assets, items, etc., without manual battery maintenance.
