- GPS tracking device: The
device fits into the vehicle and captures the GPS location information apart
from other vehicle information at regular intervals to a central server. The
other vehicle information can include fuel amount, engine temperature, altitude,
reverse geocoding, door open/close, tire pressure, cut off fuel, turn off ignition, turn
on headlight, turn on taillight, battery status, GSM area code/cell code decoded,
number of GPS satellites in view, glass open/close, fuel amount, emergency
button status, cumulative idling, computed odometer, engine RPM, throttle
position,GPRS status and a lot more. Capability of these devices actually
decide the final capability of the whole tracking system.
- GPS tracking server: The tracking server has three responsibilities: receiving data from
the GPS tracking unit, securely storing it, and serving this information on demand to the
user.
- User
interface: The UI determines how one
will be able to access information, view vehicle data, and elicit important
details from it.
A GPS tracking
unit is a device that uses the Global
Positioning System to determine the
precise location of a vehicle, person, or other asset to which it is attached and
to record the position of the asset at regular intervals. The recorded location
data can be stored within the tracking unit, or it may be transmitted to a
central location data base, or internet-connected computer, using a cellular (GPRS or SMS), radio, or satellite modem embedded in the unit. This allows the asset's location to be displayed
against a map backdrop either in real time or when analysing the track later,
using GPS tracking software.
Data tracking software is available for smartphones with GPS capability.
A GPS logger simply logs the position of the device at regular intervals in its internal memory.
Modern GPS loggers have either a memory
card slot, or internal flash
memory and a USB port. Some act as a USB
flash drive. This allows downloading of the track log data for further analyzing in a computer. The
tracklist or point of interest list may be in GPX, KML, NMEA or other format.
Most digital
cameras save the time a photo was
taken. Provided the camera clock was reasonably accurate or used GPS as its
time source, this time can be correlated with GPS log data, to provide an
accurate location. This can be added to the Exif metadata in the picture file. Cameras with GPS receiver built in can
directly produce such a geotagged photograph.
In some private investigation cases, data loggers are used to keep track of a target vehicle. The PI
need not follow the target so closely, and always has a backup source of data.
Some of the brand available in Malaysia providing GPS product and services:-
DATA FM
DF TRACKER
MYGPS
SKYTRACKGPS
ASTRATA
GPSTECH
And many others. The most important, those product must match your requirement and budget - not to be under or over specification. It has to balance between customer's satisfaction / KPI and financial impact.....
