The Research Of Navigation And Interfering Signal Simulator Control System

Navigation is a location based technology, Human needs for navigation service fleshed out. From ancient China’s compass to the radio navigation system to Doppler radar systems, navigation technology has a rapid development advances in science and technology to meet the needs of people. With the great development of space science and signal measurement, navigation satellite system which use artificial Earth satellites for navigation, came into being, and its application in military, industrial, Agriculture and people’s daily lives become increasingly popular. Navigation satellite simulator is a device can simulate the satellite signal, it plays a huge role in the development and testing process of navigation products.This paper first analyses the status and trends of navigation and interfering simulator in domestic and foreign, then introduced the GPS and compass, two representatives of the GNSS system works, also did a full research and analysis on navigation and interfering simulator’s hardware system. On this basis, paper design and implementation an integrated control platform.Paper will be classified as a human-machine interface control software module, communication module, data load module, parameters configure and function control module. The software interface development based on DevExpress controls, and the Ethernet will be used for communication between two communication modules, data processing using a background thread. Software can control the navigation satellite signal Simulator and interfering signal Simulator at the same time, so that the user can add interfering signal in order to simulate real work environment when the design and test anti-jamming receiver. The software interface has adjustable display content and variable size, so it’s easy for users to switch watch data.This paper is actively involved in research a convenient and practical and effective navigation, interfering signal simulator control software. Through modular design to completion of dismantling, making the development and application of more efficient, develop a template and reference for similar software.
