Increase of efficiency of aircraft monitoring by means of applying integrated detection system

Transition to more global systems of air navigation is caused by the restrictions imposed by ground facilities of location determination. Limitation in territorial application of ground facilities and appearing errors at determination of coordinates of object because of repeated reflection of radio waves became the reason of transition. Creation of navigation satellite systems GPS and GLONASS has turned out to be consequence of attempts to make the global radio navigational field available on all square of the globe. To solve a similar task with applying land complexes is difficult as the costs of placement and service will become inadmissible high. GLONASS and GPS systems have the minimum error of determination of location in the territory of the Russian Federation only when cooperate using. For civil needs at GPS satellites the channel has been allocated in which the error of determination of coordinates is intentionally increased. In GLONASS system inaccuracy is caused by natural sources of errors; however the degree of a covering complicates use signals only of these satellites. The task at the minimum changes in the onboard equipment of the aircraft to increase efficiency of its monitoring from the earth was set. The authors offer to use the group of low-orbital Iridium satellites for data transmission about location of the aircraft on the control office located on the earth. Data transmission is possible with the use of GSM communication through land stations, and by means of inter-satellite communication lines. The communication satellites Iridium have full coverage of a terrestrial surface that makes possible to carry out monitoring of aircrafts in remote areas. In the Russian Federation those are subpolar areas. The authors of the paper developed the scheme of monitoring in which the terminal programmed device the UTP type is placed onboard, accepting signals of satellites of navigation and via communication satellites transferring data on location of object to control office. Control office provides the analysis of the received coordinates and creation of a trajectory of flight of object.
