Civil Aircraft Precision Approach And Algorithm Research In Low Altitude Environment

With the rapid development of our country civil aviation, the flight ofcontinued growth, through the navigation, communication, radar and othertechnology to monitor and control the air traffic control methods are to beupdated. In this paper, a detailed analysis of the civil aircraft precisionapproach in a variety of ways, technology. Gradually introduced thetraditional navigation mode, and in the future, may use navigation methodand algorithm research. On the basis of this focus on the RNP precisionnavigation system.This paper introduced in most airports currently in operation method ofnavigation equipment and its principle. Based on the simulation platform, thestudy group and I analyzed the relationship between the navigation stationlayout and GDOP angle, analysis has been validated the traditional navigationmode in air traffic control application shows the limitations. MLS and DME in air traffic control in the application of gradually shown limitations. Andintroduced RNP precision navigation system, to improve China’s airspaceflow, airspace utilization rate, shorten the route.Described in detail thefunction of RNP, types, integrity, continuity, validity, research and analysisthe superiority and broad application value in China. Further described infuture planning and other technical fusion status.The rapid development of satellite navigation for the civil aviationnavigation may provide new.This paper introduced the composition of GNSS,especially China’s Beidou satellite navigation system. But satellite navigationin ATM application also has some problems, such as in aviation applicationson high dynamic and high precision positioning, integrity monitoringrequirements, it is necessary to enhance the processing of satellite navigationsystem, expand application field. Further introduces satellite navigationaugmentation system’s classification. Focuses on the United States WAAS,LAAS system etc. For our future to be used, the potential use of the GBAS,WAAS techniques are summarized and the application analysis.According tothe WAAS system precision requirements are particularly high for land-basedgeneralized precision approach algorithm, algorithm analysis discussion.Nowadays with the help of a variety of platforms, development areasignal enhancement system has important significance,and is not dependent on the satellite signal. This paper discussed the development of high-endusers regional signal enhancement system of new technology, and combinedwith the related laboratory research, simulation of a civil aircraft precisionapproach and basic performance, discussed the method of least squaresalgorithm.The simulation results show that, can greatly improve thenavigation precision and accuracy.For civil aircraft precision approachprovides a new possible.This paper introduced the precision approach algorithm improves theaccuracy of navigation, for the future of ATC navigation provides goodreference meaning and broad application value.
