communication operator with GSM standard 900/1800 or GSM
850/900/1800/1900. LBS, GPS or LBS, GPS/GLONASS are used to
determine the coordinates.
Device shall be installed out of reach of the driver.
The device is not designed to run on water transport.
Operation principles
In real time mode the tracking device:
determines location and movement parameters of the object
(time, geographical coordinates, speed, and direction).
collects and processes information from the analog, digital,
and discrete sensors
ensures control over actuating mechanisms upon command
from the control dispatching panel.
Received data are recorded and stored in an internal log, which is
implemented on microchip of nonvolatile memory. At specified intervals
or according to event entries from this log are sent to the server of the
dispatcher via the GSM network. Exchange of information is carried out
by means of GPRS and SMS channels.
Operation of the device in “on-line” mode is possible only at
presence of the network coverage. Outside GSM network coverage, the
tracking unit operates in the “black box” mode, i.e., it records all
information in the nonvolatile memory and sends it when the vehicle is
entering a GSM coverage area.
