Communications And Navigation Monitoring Coverage Simulation System By Using GIS

With the rapid development of global economy and people’s life rhythm speeding up, along with the rapid growth of the world aviation transport, air transport is becoming increasingly busy, the demand of air monitoring control technology is rising, navigation system is facing new challenge. To improve the real time monitoring of transportation capacity is one of the basic methods to ensure flight safety, reduce the flight interval and improving the utilization ratio of airspace. A radar monitor coverage system, through certain software technology combined with aviation radar technology is the modern common way to solve the problem of air control. At present, the aviation radar surveillance system is widely accepted by nations, including primary radar and the secondary radar monitoring technology. In the early, through secondary radar technology can well meet the requirements of air traffic control, but now, as a result of both primary radar and secondary radar have their own limitations, all exist a blind area. With the introduction of another kind of radar technology, automatic dependent surveillance of broadcast(ADS-B), can effectively solve the problem of the radar blind area, ADS-B is based on the broadcast ADS technology, target information by broadcasting to send a message to the adjacent flying target and ground ADS station, at the same time receive adjacent flying target message, get to know each other other’s position, so you can avoid the air crash, largely in line with the requirements of air monitoring control technology. This article is a communication and navigation monitoring coverage simulation system based on supermap GIS, combination of supermap Object.Net technology and Microsoft C#language windows form technology, by read radar configuration information and aircraft configuration information can simulate national aviation aircraft flight, at the same time, also can simulate a number of radar real-time scanning monitoring, and can be dynamically manage radar, aircraft and routes, to reach the state of the dynamic simulation of various air condition. System in reference to real ads-b and secondary radar data packet, acquire the information of targets that radar detection scans and real-time create secondary radar and ads-b message packets, the packets can be real-time sent to the air condition display system and message contrast evaluation system, provide a stable source of test data and error analysis. Combine with simulation system and air condition display system, by comparison aircraft data of two systems in real time, for the future development of civil aviation airport of automatic monitoring system has very important significance.
