3.5 Trojans and Vehicles
3.5.1 Devices for Determining Vehicle Movement Routes
Using GPS
Let us consider another interesting spy-related topic—determining position of a
vehicle using global positioning system (GPS). Today, GPS helps track vehicles on
satellite road maps with great accuracy. In order to conduct such studies, a mini GPS
receiver with a memory module must be installed under the bumper or in another
similar place providing the possibility to receive satellite signals. An example of
hidden installation of such equipment is shown in Fig. 3.20.
The received data can look, for example, as follows: “On February 20, 2017, the
car moved in the direction of the edge of the forest, where it was parked for four
minutes, after which it went to the western part of Minsk along the main highway.”
Acquisition of more precise data might require the plan of the city with names of the
streets. Digitalized maps are available for large cities.
An example of the map with the position of the tracked vehicle is shown in
Fig. 3.21; the printout contains the following data:
– Local time;
– Direction of the vehicle’s movement speed between the control points and the
distance between them;
– Actual speed;
– Coordinates.
Everyone has seen secret service agents in movies, which install a tracking device
on an object, which helps them monitor this object. How does it work? The operating
principle is as follows: the radio beacon mounted on the object emits a signal, which
was received and analyzed with the help of a direction finder: the signal increased
when approaching the object and decreased when removing from it. It was only
possible to determine location during direct search by means of movement.
