Main Functions
1. Single Locating
Tracking location, when no GPS signal, the SMS includes the last valid latitude & longitude as well as the LAC code of current position,
the LAC code can be input in the column of “manual track” menu of web platform.
2. Auto track continuously
a. Track with limited times upon time interval
b. Track with unlimited times upon time interval
c. Smart track upon time and distance interval
3. Automatic update positions of vehicle turns
The tracker will update the positions automatically to web server once the vehicle changing driving direction over pre set angle
value to form a smooth trajectory consistent with the actual road, this function is only effective in GPRS mode.
4. GPS drift suppression
The GPS data stop updating if vehicle is not moving and latitude and longitude always keep same, and GPS data updates
automatically when vehicle is moving.
5. Get absolute street address
Note: You must set up the APN of your local GSM network for the SIM card in tracker first before using this function.
6. Location based service (LBS)
When the tracker device doesn\'t received valid GPS signals, tracker will locate by LBS, the messages includes the GPS
coordinates of the last position in SMS mode, but the LAC in message is the current new position, the location can be seen
by input the LAC code in the menu “Manual Track” of web platform ;gpstrackerxy.com, you can also send command “address+password” to tracker to get the newest absolute address and newest GPS coordinates as well; tracker will automatically switch to track by location based service in GPRS mode, and actualized on the map of web server with
LBS mark. And there may be some inaccuracy with actual location by LBS tracking; the bias depends on GSM reception.
Note: This feature can be used normally in most areas according to the signal of GSM network. It may not be available
in some areas.
7. Check the Vehicle State.
8. Check IMEI
9. Terminal (local) Time Setting
10. Monitor (Voice Surveillance)
The default mode is “track” (Track mode). Send SMS “monitor+password” to the unit, and it will reply “monitor ok!” and switch
to “monitor” mode.
11. Data Logging
Logging Volume: Built-in flash 1MB (store about 16,000 positions); expanded volume depends on the SD card inserted.
12. Data Load
13. Forward the third parties\' message
14. Cut off the Oil and Power System
a. Execute immediately Mode
Send command “quickstop+password” to tracker, it will reply “quickstop OK”. Then tracker will stop the car immediately after “stop” command. Send command “stop+password” to tracker, tracker will execute it and reply “Stop engine Succeed”.
And it will remain immobile state until next command to resume.
b.Execute depends on speed(Default mode)
Send command “noquickstop+password” to tracker, It will reply “noquickstop OK”, Then the tracker won\'t stop the car
immediately after “stop” command during the speed above 20KM/H, instead, it will reply “it will be executed after speed less than 20KM/H”, and stop the car when the speed is less than 20KM/H.
15. Resume the Oil and Power System
16. Sleep Mode
a. Sleep by time
Send "sleep+password+space+time", tracker will reply "sleep time ok" if none of the alarms listed under chapter IV has been set and no operations, tracker will fall asleep in 5 minutes, LED will be off, calling or SMS can awake the tracker. If these alarms have been set, tracker will enter sleep by detecting shock sensor. And tracker will sleep by time as default.
b. Sleep by shock sensor
Send "sleep+password+space+shock", tracker will reply "sleep shock ok", it will enter sleep mode after detect no shock, and LED will be off.
17. No sleep mode
18. Geo-fence
19. Multi-area management
20. Movement alert
21. Overspeed alert
22.Accident alarm (Optional)---If you need this function, you add extra $6 for it will be ok!
When tracker detects accident occurred (severe impact), it will send " Accident! + latitude & longitude " to all authorized phone numbers.
