How does your tracker’s localisation feature work?
It can sometimes be frustrating to discover that the GPS localisation isn’t quite as accurate as hoped. This is because it is subject to several factors that have a direct impact on the information that you receive. Rest assured, you will always be able find your loved one; but the accuracy of the tracker will sometimes be less than perfect.
Differentiating GPS signal from connection to the server
To begin with, it is important to note the difference between your tracker’s GPS signal (which depends on GPS satellites) and GSM connection (which depends on network coverage). These two aspects are essential but do not serve the same function.
GPS signal
A valid GPS signal is how your tracker can get its position from satellites in orbit in the atmosphere. It is equipped with a unit and a GPS antenna which allow it to receive GPS signal sent by the satellites. If the GPS signal is valid the tracker will be able to get the latitude and longitude of its current position. If the GPS signal is invalid it will be incapable of retrieving the GPS coordinates of its current position.
Summary
With no GPS signal there is no information to send; but without a connection to the server the information cannot be sent.
