【摘要】：自從衛(wèi)星導(dǎo)航系統(tǒng)出現(xiàn)至今在全球范圍內(nèi)大量投入使用,其優(yōu)良的導(dǎo)航性能已經(jīng)被全世界所公認(rèn)。但近些年來,人們開始逐漸清楚的認(rèn)識(shí)到衛(wèi)導(dǎo)系統(tǒng)自身存在的問題和不足。并且意識(shí)到如果將衛(wèi)星導(dǎo)航定位系統(tǒng)用于未來僅有的導(dǎo)航定位手段是不可取的。為了降低衛(wèi)星導(dǎo)航定位系統(tǒng)的使用風(fēng)險(xiǎn),俄羅斯、英國(guó)、美國(guó)等少許導(dǎo)航發(fā)展先進(jìn)國(guó)家都無疑的積極探索、強(qiáng)化其陸基無線電導(dǎo)航系統(tǒng)在現(xiàn)實(shí)中的應(yīng)用,特別對(duì)羅蘭C系統(tǒng)的發(fā)展和應(yīng)用做了進(jìn)一步考量[1]。一方面從我國(guó)的實(shí)際國(guó)情考慮,另一方面借鑒導(dǎo)航先進(jìn)國(guó)家的成功經(jīng)驗(yàn),對(duì)于衛(wèi)星導(dǎo)系統(tǒng)目前存在的系統(tǒng)風(fēng)險(xiǎn)我們清楚地認(rèn)識(shí)到:我國(guó)不僅僅要大力提高開發(fā)和應(yīng)用北斗導(dǎo)航系統(tǒng)水平,同時(shí)也必須繼續(xù)大力發(fā)展陸基無線電導(dǎo)航系統(tǒng)的應(yīng)用范圍。一方面,陸基無線電導(dǎo)航系統(tǒng)羅蘭C可以作為衛(wèi)導(dǎo)系統(tǒng)的良好補(bǔ)充;另一方面,依靠衛(wèi)導(dǎo)系統(tǒng)的即時(shí)定位準(zhǔn)確性對(duì)羅蘭C的定位誤差A(yù)SF(附加二次相位因子)修正進(jìn)行校準(zhǔn),進(jìn)而有效地提高了我國(guó)羅蘭C系統(tǒng)應(yīng)用的導(dǎo)航定位誤差;大大改善導(dǎo)航定位的幾何因子和定位精度,并且組合使用可以有效降低衛(wèi)導(dǎo)系統(tǒng)使用的風(fēng)險(xiǎn)。本文立足于對(duì)羅蘭C系統(tǒng)和衛(wèi)星導(dǎo)航系統(tǒng)的優(yōu)點(diǎn)和不足,以及當(dāng)前國(guó)際形勢(shì)下國(guó)外發(fā)達(dá)國(guó)家對(duì)兩種系統(tǒng)的應(yīng)用,引出羅蘭C導(dǎo)航系統(tǒng)與衛(wèi)星導(dǎo)航系統(tǒng)組合應(yīng)用的研究?jī)?nèi)容、方向和必要性,進(jìn)而對(duì)系統(tǒng)的需求和可行性進(jìn)行了分析。論文對(duì)系統(tǒng)總體結(jié)構(gòu)設(shè)計(jì)進(jìn)行了整體闡述,并以三個(gè)主要功能模塊為基礎(chǔ)展開,詳細(xì)敘述了羅蘭C系統(tǒng)和衛(wèi)星導(dǎo)航系統(tǒng)數(shù)據(jù)接收模塊、導(dǎo)航系統(tǒng)定位結(jié)果組合策略模塊、羅蘭C系統(tǒng)ASF修正庫模塊的設(shè)計(jì),有效的實(shí)現(xiàn)了系統(tǒng)同時(shí)接收羅蘭C和衛(wèi)星導(dǎo)航定位數(shù)據(jù),并通過組合策略實(shí)現(xiàn)四種工作模式的ARINC429格式數(shù)據(jù)輸出。通過實(shí)時(shí)接收的衛(wèi)星導(dǎo)航定位數(shù)據(jù)完善了傳統(tǒng)羅蘭C在ASF修正庫中的應(yīng)用,實(shí)現(xiàn)了對(duì)采集庫和存儲(chǔ)庫充分利用。同時(shí)通過實(shí)地東南沿海跑車積累了大量數(shù)據(jù),通過對(duì)跑車線路和圖形數(shù)據(jù)的分析充分的驗(yàn)證了系統(tǒng)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.
