The GPS logging function is good for people who need to record their trace logs of activities, such as traveling,
hiking, etc., from their GPS Tracker which they can see visualized routes and share with others later on Google
Earth.
The GPS Tracker provides a System monitor function to let others get an alert message when the battery of GPS
Tracker is running low or the trace log files have filled up the storage card in the GPS Tracker. This function
allows others to take action necessary to keep the GPS Tracker working properly.
