【摘要】:自从卫星导航系统出现至今在全球范围内大量投入使用,其优良的导航性能已经被全世界所公认。但近些年来,人们开始逐渐清楚的认识到卫导系统自身存在的问题和不足。并且意识到如果将卫星导航定位系统用于未来仅有的导航定位手段是不可取的。为了降低卫星导航定位系统的使用风险,俄罗斯、英国、美国等少许导航发展先进国家都无疑的积极探索、强化其陆基无线电导航系统在现实中的应用,特别对罗兰C系统的发展和应用做了进一步考量[1]。一方面从我国的实际国情考虑,另一方面借鉴导航先进国家的成功经验,对于卫星导系统目前存在的系统风险我们清楚地认识到:我国不仅仅要大力提高开发和应用北斗导航系统水平,同时也必须继续大力发展陆基无线电导航系统的应用范围。一方面,陆基无线电导航系统罗兰C可以作为卫导系统的良好补充;另一方面,依靠卫导系统的即时定位准确性对罗兰C的定位误差ASF(附加二次相位因子)修正进行校准,进而有效地提高了我国罗兰C系统应用的导航定位误差;大大改善导航定位的几何因子和定位精度,并且组合使用可以有效降低卫导系统使用的风险。本文立足于对罗兰C系统和卫星导航系统的优点和不足,以及当前国际形势下国外发达国家对两种系统的应用,引出罗兰C导航系统与卫星导航系统组合应用的研究内容、方向和必要性,进而对系统的需求和可行性进行了分析。论文对系统总体结构设计进行了整体阐述,并以三个主要功能模块为基础展开,详细叙述了罗兰C系统和卫星导航系统数据接收模块、导航系统定位结果组合策略模块、罗兰C系统ASF修正库模块的设计,有效的实现了系统同时接收罗兰C和卫星导航定位数据,并通过组合策略实现四种工作模式的ARINC429格式数据输出。通过实时接收的卫星导航定位数据完善了传统罗兰C在ASF修正库中的应用,实现了对采集库和存储库充分利用。同时通过实地东南沿海跑车积累了大量数据,通过对跑车线路和图形数据的分析充分的验证了系统功能的完整性和可靠性。
[Abstract]:Since the appearance of satellite navigation system, it has been widely used in the world, and its excellent navigation performance has been recognized all over the world. However, in recent years, people began to recognize the problems and shortcomings of the guidance system itself. And realized that if the satellite navigation and positioning system is used in the future only navigation and positioning means is not desirable. In order to reduce the risk of the use of satellite navigation and positioning systems, Russia, Britain, the United States and other advanced countries in navigation development are undoubtedly actively exploring to strengthen the application of their land-based radio navigation systems in reality. In particular, the development and application of Roland C system are further considered [1]. On the one hand, considering the actual national conditions of our country, on the other hand, learning from the successful experiences of advanced countries in navigation, It is clear to us that China should not only improve the level of development and application of Beidou navigation system, but also continue to develop the application scope of land-based radio navigation system. On the one hand, the land-based radio navigation system Roland C can be used as a good supplement to the satellite guidance system; on the other hand, the positioning error ASF (additional quadratic phase factor) correction of Loran C can be calibrated by the real-time positioning accuracy of the satellite guidance system. Furthermore, the navigation and positioning error of Loran C system in China is improved effectively, the geometric factors and positioning accuracy of navigation and positioning are greatly improved, and the risk of using satellite guidance system can be effectively reduced by combined use. Based on the advantages and disadvantages of Loran C system and satellite navigation system, and the application of the two systems in developed countries in the international situation, this paper introduces the research contents of the integrated application of Roland C navigation system and satellite navigation system. The direction and necessity of the system are analyzed. In this paper, the overall structure design of the system is described, and based on the three main function modules, the data receiving module of Roland C system and satellite navigation system, the integrated strategy module of navigation system positioning results are described in detail. The design of ASF correction library module in Roland C system realizes the system to receive Loran C and satellite navigation and positioning data at the same time, and realizes the ARINC429 format data output of four working modes by combining strategy. The application of traditional Roland C in ASF correction library is perfected by the satellite navigation and positioning data received in real time, and the collection database and repository are fully utilized. At the same time, a large amount of data have been accumulated through the southeast coastal sports cars in the field, and the integrity and reliability of the system functions have been fully verified by the analysis of the roadster circuit and graphics data.
