GPS is great for asset tracking because it gives a precise location. However, when GPS signal can’t be fixed (i.e. in the subway or underground parking), this method does not work anymore.
Nevertheless, you can still define the location roughly – with the help of GSM signals.
GSM cell-based location is very important for security applications (like car anti-theft, kids safety). Also, it is helpful for long distance goods tracking – when the goods are shipped in metal containers or when internal battery consumption matters, but the precise location is not absolutely necessary.
LBS location is fixed based on the cell-towers data which is received from the device. Usually, the device will find nearest cell-tower and will show it’s location near it.
Navixy natively supports LBS feature and especially GSM cell-based location for many tracking devices. In most cases the combination of GPS and GSM is used: when there is no GPS data, the system uses LBS as a backup. For example, when a car enters an underground parking, the observer can see last known accurate GPS location and current GSM-based location (with some accuracy range).
However, LBS location provided by the device is usually much less accurate than GPS one. If you want to cut LBS points which are too far from the original device location, you can use “LBS detection radius” portlet in “Devices and settings”:
Setting it to “0m” will cut LBS points from showing in the interface, and tracking history.
My device sends only LBS points – why?
This could happen because of the several reasons:
- The device can’t get GPS signal because of it’s location – perhaps your device stands in the garage, or in an underground parking. Also, please check the device installation in the car.
- GPS antenna of the device does not work – please check it’s connection with the device, and it’s placement: the best place is under the windshield
- GPS module of the device is not working – it could happen sometimes, in this case, we recommend to contact your local dealer to replace the device with the working one.
