Description

MOBILE LOCATION DETERMINATION SYSTEM

The proposed utility model relates to the field of radio engineering and can be used to determine the location of moving objects.

Known, chosen as the closest analogue, a satellite system for determining the location of moving objects containing artificial earth satellites, signal sensors installed on moving objects, receiving stations installed stationary at reference points with known geographical coordinates, a control station (Balashov AI. And others. International Space Radio Engineering Disaster Detection System, Moscow: Radio and Communications, 1987, p. 64).

The disadvantage of this system is that the coordinates of moving objects are determined with low accuracy, which is associated with various effects on the transmitted signals (for example, electromagnetic waves, radio waves, etc.)

The technical task of the proposed system is to increase the reliability of the determined coordinates of moving objects.

The problem is achieved in that in the system for determining the location of moving objects containing artificial earth satellites, a dispatch station, receiving stations installed stationary at reference points with known geographical coordinates, GPS receivers connected to artificial earth satellites installed on moving objects, receiving stations are introduced and dispatching station, while receiving stations installed stationary at reference points with known coordinates are interconnected and with a computer station via the Internet; at the same time, receiving stations installed stationary at reference points with known coordinates are connected with each other and with the control station using a wired network; at the same time, receiving stations installed stationary at reference points with known coordinates are connected with each other and with the control station using artificial earth satellites.

OBJECTS

-1-1, 1-2 ... 1-K - artificial earth satellites;

-2-1, 2-2 .. .2-N - GPS-receivers installed on moving objects;

-3-1, 3-2 ... 3-M-receiving stations installed stationary at reference points with known geographical coordinates;

-4-1, 4-2 ... 4-M - GPS receivers installed at receiving stations,

-5 - dispatch station;

-6 - GPS-receiver installed at the control station.

The system for determining the location of moving objects works as follows.

GPS receivers 4-1 - 4-M, 6 installed at receiving stations 3-1 - 3-M and control station 5 are constantly in working mode, exchanging information with those of satellites 1-1 - 1-K, which are located in the zone the reach of their signal, receiving information about their coordinates with any error. The receiving stations 3-1 - 3-M and the dispatching station 5, equipped with computers in which information about their exact geographical coordinates are entered in advance, compare the information received from satellites 1-1 - 1-K about their geographical coordinates with a priori known coordinates, determining the error in measuring the geographical coordinates at each moment in time. After that, each of the receiving stations 3-1 - 3-M via the Internet transmits information about its measurement error of geographical coordinates to the control station 5, where the average correction for the measurement of geographical coordinates for all receiving stations 3-1 - 3-M is calculated. Then this amendment is transmitted over the Internet to each of the receiving stations 3-1 - 3-M. Instead of the Internet, a local wired network can be used, or communication can be carried out using artificial earth satellites 1-1 - 1-K.

GPS receivers 2-1 - 2-N installed on mobile objects receive information about their geographical coordinates from artificial earth satellites 1-1 - 1-K located in the range of their signal, then they receive from one of the GPS receivers 4- 1 - 4-M installed on the nearest receiving station 3-1 - 3-M information about the average correction in the measurement of geographical coordinates, specify their coordinates and transmit information about them to one of the GPS receivers 4-1 - 4-M installed on the nearest of the receiving stations 3-1 3-M. Then one of the receiving stations 3-1 - 3-M, which received information about the coordinates from any of the GPS receivers 2-1 - 2-N installed on one of the moving objects, transmits it via the Internet to the dispatch station 5.

Thus, by introducing GPS receivers installed on mobile objects, receiving stations and a dispatching station into the system for determining the location of moving objects, and by quickly exchanging information between receiving stations and a dispatching station via the Internet, it is possible to determine the measurement error of geographical coordinates and how The consequence of this is increased reliability of the determined coordinates of moving objects.
