Terms and Definitions
GPS is a US-made satellite geographical positioning system. Signals from GPS satellites en-
able the customer’s GPS receiver to calculate its current geographical coordinates, speed
and its travel direction.
GLONASS (ГЛОНАСС) is a Russian-made navigation system. Its basic difference from the
GPS system is that the orbital rotation of GLONASS satellites is not synchronous with the
rotation of the Earth and this provides for their greater stability.
Analysis Report is information of a Vehicle or a group of Vehicles operation for the selected period of time (normally a day, a week, a month). It may contain figures, tables, graphs,
a map with the Vehicle’s route shown, diagrams.
Additional sensors are not standard sensors mounted on the Vehicle by the Manufacturer.
Normally these are: a fuel level sensor, a fuel consumption sensor, an axle load sensor, a
temperature sensor.
Reports Generation Interval is a setting that sets a time period for generation of this or
that Report on the Tracking Device. In СКРТ you may set different intervals for different
types of Reports. 15 sec intervals are normally used to transmit data on the actual coordinates of the Vehicle and 60 sec intervals are used for Reports containing data on the Vehicle
operation.
Maps are images (vector or raster images ) used in Service Servers. Generally maps received from Google Maps, Openstreetmap etc are used.
A Route is a data array containing the coordinates, speed and travel direction of the Vehicle corresponding to the Vehicle route across a given area. The Route is usually represented
on the map as a series of dots connected with lines. Dots are often presented as arrows indicating the direction.
Operational Data is the latest data received from the Vehicle including the coordinates and
basic parameters of its operation. The Operational Data is updated on the Server as soon as
the latest Operational Data is received.
Reports (On-Board Reports) are data recorded by the Tracker at certain intervals (Regular Reports) or in case of an Event (Event Reports).
Event Reports are Reports generated in case of a certain Event and contain information on
the time, Parameters and Counters related to the Event.
Parameter is a characteristic of the Vehicle varying with time (increase/decrease). E.g.
speed, volume of fuel in the tank, coordinates. A Parameter is usually presented as a graph
and average value.
Regular Reports is a type of On-Board Reports regularly generated by the Tracker, in accordance with the interval of their generation set in the Settings, e.g. every second, every
minute etc. 1 minute interval is most commonly set in vehicle tracking systems.

СКРТ Users are personnel having access to data in the СКРТ system. СКРТ system has the
following User grades (with ascending authority):
driver;
transportation company managers;
Installer;
Regional service centers;
Manufacturer.
Instant Fuel Consumption is fuel consumption per 100 km of travel distance. This parameter
has a very wide range from 1 l/100 km (the vehicle is coasting from a hill, the engine is
idling) to 1000 l/100 km (a heavily loaded vehicle is slowly riding in a traffic jam).
Fuel Consumption is the value of the fuel volume consumed by the Vehicle for a certain
time period. It is measured in liters (do not confuse it with the fuel consumption per hour
and Instant Fuel Consumption
Real-Time Mode (Online Mode) is the СКРТ System mode of operation in which On-
Board Reports are immediately transmitted to the Server. Real-Time Mode requires no permanent availability of GSM network.
Event is a comparatively rare and abrupt change of Parameters. E.g. a drastic increase of
volume of fuel in the tank is an Event called “Filling”. The Event may have one or a few
characteristics. Thus, the “Filling” Event has the following characteristics: “volume of fuel at
the beginning of “Filling”, “volume of fuel at the end of “Filling”, “volume of “Filling”, etc. As
soon as the Event is identified, the Tracker records the time of the Event which is subsequently specified in the Event Report. The Event is always “linked” to the time and place
where it was identified.
Service Server is hardware and software designed for processing and storage of On-Board
Reports as well as for generation and presentation of Analysis Reports via Internet. It has
its permanent Internet address..
Counter is a digital accumulation characteristic. It can only increment with time. The Counter is presented as one number, e.g. fuel consumption, the distance covered, engine hours
counter.
Tracker is an element of the vehicle tracking system performing the function of reading data from standard sensors mounted by the Manufacturer and additional sensors mounted on
the Vehicle, reception of signals of coordinates from navigation satellites and transmission
of data to the Service Server. .
Access Point is an element of the Vehicle Tracking System designed to receive data from
vehicles and transmit it to the Service Server or to the Customer software. Each Access
Point is allocated a special Communications Channel.
GPRS Access Point (GPRS AP) is a computer with an assigned IP address, database and applied software. GPRS AP is the basic one for Online Tracking Device.
SMS Access Point (SMS AP) is a computer with a GSM modem (a telephone) connected to it,
a database and applied software. SMS AP is an alternate Access Point used by online Tracking Device in case the connection with GPRS AP is not available, e.g. while using roaming.
Vehicle is an object controlled by the Vehicle Tracking System. This is generally a truck, a
bus or a tractor, sometimes a locomotive, a ship, a utility vehicle. From the point of view of
Vehicle Tracking System, fixed equipment such as diesel generators, heating boilers, burners and so on are considered as Vehicles.

Installer is a СКРТ User who is in charge of installation and adjustment of the Vehicle
Tracking System elements on the Vehicle. Sometimes he takes part in the installation of the
customer software. As a rule, Installers undergo special training by the Manufacturer.
Functional Module is the hardware/software Tracker component that has no separate casing; i.e. it is built into the Tracker itself.
Fuel Consumption per Hour is a quickly changing parameter that characterizes the volume of fuel instant consumption by the Vehicle. It is measured in liters per hour. It amounts
to 2-4 l/hour for trucks in the idling mode, 20-50 l/hour for average load. The maximum
fuel consumption per hour might be 100 and more liters per hour.
Standard Sensors are sensors installed by the Vehicle Manufacturer (speed sensor, engine
rpm sensor, open door sensor, engine temperature sensor, oil pressure sensor and so on).

Figure 3 — Diagram showing how the Vehicle Tracking System operates.
The Tracking Device mounted on the Vehicle identifies its geographical position, speed and
travel direction based on signals received from navigation satellites. The Tracking Device also receives signals from on-board equipment sensors connected to it and records values of
all parameters into its internal memory.
Then Reports (see 2.9) are generated either at preset intervals, or in case of a certain Event
which are transmitted to the Access Point (further on AP) by means of GPRS or SMS messages. The Access Point, in its turn, transmits the received data to one or several Service
Servers, e.g. to the ORF Monitor Vehicle Tracking Service.
Users, if they have a Web-browser and Internet access, may view the Reports at the Service Server. Analysis Reports are an alternative to trip sheets. They contain detailed information which is needed for efficient monitoring vehicles and drivers: working schedule,
time and place of stops, fuel consumption, filling the Vehicle and draining fuel from the
tank, the route, speed i.e. dozens of parameters.
