CLAIMS
1. A system for recording the motion characteristics of vehicles and for reconstructing such motion characteristics visually according to such records when necessary, said system being characterized by comprising

a satellite group providing at least the geographical location information in an adequate frequency,

at least two satellite receivers, which are positioned on at least two different locations on the vehicle so as to sufficiently define the vehicle's shape, and which receive at least the respective vehicle's geographical location information from said satellite group with a frequency adequate enough to define said vehicle's motion behavior,

a control unit, recording at least the respective geographical location information of each individual receiver supplied from said satellite receivers by correlating said information with the correct receiver, and

optionally, a computer system at least reconstructing visually the vehicle's motion characteristic based on the geographical location information received from a memory unit.

2. A system according to Claim 1 , wherein said satellite group provides the geographical location information preferably in a frequency of at least of one tenth (1/10) of a second and accordingly, said satellite receiver requests this location information in the same frequency.

3. A system according to Claim 1 , wherein said satellite receivers are enclosed in cases which prevent any damage to occur on said receivers.

4. A system according to any of the preceding claims, wherein each satellite receiver on the vehicle is spared with at least one satellite receiver against the risk of becoming damaged during an accident.

5. A system according to any of the preceding claims, wherein at least the front, rear, and upper side of the vehicle are provided with at least one apiece satellite receivers.

6. A system according to any of the preceding claims, wherein said satellite group provides also the speed information of the vehicle in an adequate frequency, whereas said satellite receivers receive this speed information.

7. A system according to Claim 1 , wherein said control unit is enabled to record the data from some terminal sensors within the vehicle by correlating such data to the geographical location data from the satellite receivers to keep records of the vehicle's traveling data.

8. A system according to Claim 7, wherein said terminal sensors are selected from a group comprising the devices determining the information on instantaneous vehicle-speed, braking moments, impacts status, following distance to a front-traveling vehicle, any red light violation status, vehicle's balance status, and traffic lane changes.

9. A system according to any of the preceding claims, wherein at least those data on the vehicle's size, on the position of such receivers on the vehicle, and on the relative distances between the receivers are set or defined in the control unit along with certain tolerances, so that the control unit makes comparison on the data received from the satellite receivers in order to make records of any extraordinary circumstances deviating from such definitions kept on the memory.

10. A system according to any of the preceding claims, wherein said control unit increases and decreases the recoding frequency as the vehicle is accelerated and decelerated, respectively.

11. A system according to any of the preceding claims, wherein said control unit detects the accident moment or makes an estimate of a probable accident to occur, and subsequently increases the recording frequency at least to 30 times per second independently from the vehicle's speed.

12. A system according to any of the preceding claims, wherein said computer system visually reproduces the vehicle's traveling course and/or driving behavior on such course and/or any accident moments on such course, based on the location information it receives from the satellite receivers.

13. A system according to Claim 12, wherein three-dimensional images of an adequate amount of vehicle models and roads are kept recorded on said computer system, whereby said system is capable to reproduce any accident moment on a 3D medium in accordance with such reference data.

14. A system according to Claim 12, wherein said computer system comprises a digital map, and correlates the geographical location information received from the vehicle to said digital map.

15. A system according to Claim 14, wherein on said digital map, the traffic rules of each road are kept recorded, whereas the computer system compares any geographical location information and vehicle's traveling information received from the vehicle to the digital map so as to determine any rule violations.
I Vl

16. A system according to Claim 12, wherein said computer system is positioned preferably on certain headquarters.

17. A method for recording the motion characteristics of vehicles and for reconstructing such motion characteristics visually according to such records when necessary, said method comprising the steps of providing the satellite receivers at least with the geographical location information in an adequate frequency by a satellite group providing at least the geographical location information in an adequate frequency,

determining and recording in an adequate frequency the location information of at least two different points on the vehicle to adequately define the respective vehicle's shape, based on the geographical location information received from said satellite group, and

optionally, reconstructing the motion characteristic of said vehicle in a visual manner based on said location information.

18. A method according to Claim 17, wherein in steps (a) and (b), said satellite group provides the geographical location information preferably in a frequency of at least of one tenth (1/10) of a second, whereas said satellite receiver queries the location information by the same frequency.

19. A method according to Claim 17, wherein in step (b), at least the geographical location information of the vehicle's front, rear, and top are recorded.

20. A method according to Claim 17, wherein in step (c), the data fed by some terminal sensors in the vehicle are also recorded by correlating such data to the geographical location data fed by the satellite receivers.

21. A method according to Claim 20, wherein said terminal sensors are selected from a group comprising the devices determining the information on instantaneous vehicle-speed, braking moments, impacts status, following distance to a front-traveling vehicle, any red light violation status, vehicle's balance status, and traffic lane changes.

22. A system according to any of the claims 17 to 21 , wherein step (c) comprises the sub-step of defining at least those data on the vehicle's size, the position of such receivers on the vehicle, and the relative distances between the receivers along with certain tolerances, and comparing such defined values to data fed by the satellite receivers in order to make records of any extraordinary circumstances.

23. A system according to any of the claims 17 to 21 , wherein step (c) comprises also the sub-step of determining the vehicle's speed, and of increasing and decreasing the recording frequency, respectively, as the vehicle is accelerated and decelerated.

24. A system according to any of the claims 17 to 23, wherein step (c) comprises also the sub-step of detecting the accident moment or making an estimation of a probable accident, and subsequently increasing the recording frequency up to 30 times per second minimum, independently from the vehicle's speed.

25. A system according to any of the claims 17 to 24, wherein step (d) is performed to visually reproduce the vehicle's traveling course and/or driving behavior on such course and/or any accident moments.

26. A system according to Claim 25, wherein in step (d), three-dimensional images of an adequate amount of vehicle models and roads are recorded, whereby the reproduction operation is performed on this 3D medium.

27. A system according to any of the claims 17 to 26, wherein step (d) comprises also the sub-steps of correlating the geographical location information received from the vehicle to a digital map including traffic rules of each contained road, comparing the geographical location information and the vehicle's traveling information to the digital map, and determining any traffic rule violations.
