GPS tracker+data logger to ensure no loses of tracking data
For the GPS tracking, GSM network problem happens and it can make the tracking data lose.
With the data logger, it can ensure no loses of tracking data.
Most of the fleet comapnies are using this practical solution now.
1. Huge capacity storage is available. Car tracker can store data over 1 year. Rather than common GPS data logger, storage extension is an easy job.
2. New Data upload mode.Tracking data will be saved as packets, and uploaded via a different process with normal data. That mean no transmission interference, reduce the chance of lose data caused by interference.
3. Confirm message from server. Server sends confirm message after receiving data complete, or else, tracker reloads the data again. Make sure no miss a tracking data.
