CHARACTERISTICS 

 

1.1 Purpose of the system 

 

The equipment is a GPS-GSM Based Vehicle Tracking System. It is allowed to use the following terms in relation to this 

device: “system”, “product”, “equipment”, “device” “terminal”, “tracker”.  

The system is designed for: 

 

vehicle monitoring: its location, track, mileage, fuel consumption, engine hours; 

 

driving style determination (EcoDriving); 

 

emergency informing about vehicle hijacking; 

 

emergency informing about attacks on the driver or passengers and other accidents; 

 

processing and transmitting of data to the server from devices such CAN bus adapters, RFID tag reader, fuel level 
sensors; 

 

monitoring the temperature using temperature sensors; 

 

remote control of connected devices and vehicle systems, such as a siren, engine and door lock system, etc. 

 

Recipients of information from the system can be: 

 

centralized dispatch centers; 

 

end-users (corporate and private car owners, proxy persons, etc.) 

 

 

1.2 System tasks 

 

The system operation consists of the following tasks: 

 

telemetering  record  of  vehicle  location,  speed,  direction  and  mileage  according  to  the  GPS/GLONASS  satellite 
information;  

 

telemetering  record  from  the  contact,  impulse,  analog  connected  sensors  and  CAN  bus;  monitoring  of  vehicle 
battery voltage and device built-in battery voltage; 

 

fuel consumption, drains and fills monitoring; mileage monitoring; stoppage time and off-track monitoring;

 

places 

of cargo loading/unloading monitoring; 

 

events data record to the nonvolatile memory, possibility of its remote reading and analyzing; 

 

 sustained or specified time period transmission of information about current and past events on the vehicle via 
GPRS-channel to the telematics server for further analyzing, visualization and report formation; 

 

customer SMS informing on sensors activation;  

 

connected external devices control (for example, siren on/off) by SMS command or by preset settings in automatic 
mode; 

 

control of cargo safety by comprehensive measures; improving driver and passenger’s safety. 

 

 

1.3 Operational principles 

 
The device during its operation continuously monitors the status of the connected sensors, vehicle battery voltage, 

built-in device battery voltage, GSM modem signal level, operational capability of navigational sensor (GPS/GLONASS), etc.  

At power-up or USB connection to a computer the device automatically turns on. At power-off or USB disconnection 

the device continues its operation from built-in battery. The device turns off when the built-in device battery is discharged 

to 3V. 

Upon the occurrence of an event set by the device logic (set by the user or device manufacturer), the telematics 

information is recorded into nonvolatile memory and is sent to tracking platform as a message with a set of parameters. 

Events for messages formation can be change of direction, timer activation in motion or in stand, activation of input sensor, 

value changes of analog or digital sensor, etc. Each message is recorded with its sequence number and has its own code 

that determines the reason for its formation. When sending message packets after reconnecting to tracking platform, the 

earlier messages are sent first. Some messages generated by “alarm” events (pressing the panic button, impact sensor 

detection, etc.) are sent out of turn, immediately after the “alarm” event has happened. After message packet sending to 
the server, the device is waiting for server answering. If there is no answering from the server, the device will try to send 

message again until it receives answering about data transferred, in this case the next packets from the queue will not be 

sent. This algorithm set in the data transfer protocol ensures reliable sending of all messages to the server, even in case 

of data transmitting failure.   

The  device  operation  parameters  are  configured  using  proprietary  software,  the  NTC  Configurator  program.  For 

proper software operation there is a requirement for a computer with MS Windows 7 or higher operating system. 

It is also possible to perform basic settings via Bluetooth, USB, GSM channels using the NTC Control program - a 

mobile application for smartphones and tablets running the Android operating system.
