【摘要】：隨著硬件衛(wèi)星接收機技術(shù)的日益成熟,目前導(dǎo)航定位接收機的研究熱點逐漸轉(zhuǎn)移到了軟件衛(wèi)星接收機,而隨著我國北斗二號衛(wèi)星的成功建設(shè),掌握擁有自主知識產(chǎn)權(quán)的接收機核心技術(shù)也勢在必行。軟件衛(wèi)星接收機除了能實現(xiàn)硬件衛(wèi)星接收機的常用功能,還能為商業(yè)硬件接收機的開發(fā)和性能優(yōu)化作研發(fā)依據(jù),因此,對軟件接收機的關(guān)鍵技術(shù)進行優(yōu)化設(shè)計作為一項基礎(chǔ)知識的研究,有著一定的應(yīng)用前景。 本論文在簡要介紹了衛(wèi)星導(dǎo)航定位的原理后,對軟件衛(wèi)星接收機的關(guān)鍵技術(shù)進行了詳細的分析,比較了經(jīng)典熱門算法,并在此基礎(chǔ)上進行了優(yōu)化。主要分析和優(yōu)化了捕獲環(huán)節(jié)和跟蹤環(huán)節(jié)的算法：總結(jié)了串行搜索法、并行搜索法等的優(yōu)缺點,并且將比特分割算法與差分相關(guān)算法進行了更好的組合,能針對微弱信號進行良好的捕獲；總結(jié)了碼跟蹤和載波跟蹤的原理,針對載波跟蹤的環(huán)路濾波器進行了分析設(shè)計,并且通過仿真分析,驗證了加入慣性輔助和卡爾曼濾波技術(shù)的載波環(huán)具有良好的動態(tài)跟蹤效果。最后,使用了通用的高性能的接收機芯片MAX2769和帶有微處理器的USB芯片CY7C68013,對接收機中的硬件部分——中頻前端進行了合理設(shè)計。 分別進行了靜態(tài)和動態(tài)實驗,采集了中頻數(shù)據(jù),使用優(yōu)化的算法對中頻數(shù)據(jù)進行處理,并與高精度的硬件接收機輸出數(shù)據(jù)進行對比,驗證了算法的可行性；在對定位數(shù)據(jù)進行濾波處理后,可得出符合用戶精度需求的位置信息。
[Abstract]:With the development of hardware satellite receiver technology, the research focus of navigation and positioning receiver is gradually transferred to software satellite receiver, and with the successful construction of Beidou 2 satellite in China. It is also imperative to master the core technology of the receiver with independent intellectual property rights. The software satellite receiver can not only realize the common functions of the hardware satellite receiver. It can also be used as the basis for the development and performance optimization of commercial hardware receivers. Therefore, the optimization design of the key technologies of software receivers as a basic knowledge has a certain application prospects. After a brief introduction of the principle of satellite navigation and positioning, the key technologies of the software satellite receiver are analyzed in detail, and the classical popular algorithms are compared. And on this basis, the optimization. The main analysis and optimization of the capture and tracking links of the algorithm: summed up the serial search method, parallel search method and so on advantages and disadvantages. The bit segmentation algorithm and the differential correlation algorithm are combined better, which can capture the weak signal well. The principles of code tracking and carrier tracking are summarized. The loop filter of carrier tracking is analyzed and designed, and the simulation analysis is carried out. It is verified that the carrier loop with inertial assistant and Kalman filter has good dynamic tracking effect. Finally. The general high performance receiver chip MAX2769 and the USB chip CY7C68013 with microprocessor are used. The hardware part of the receiver, if front-end, is designed reasonably. The static and dynamic experiments were carried out, the if data were collected, and the if data were processed by the optimized algorithm, and compared with the output data of the high precision hardware receiver, the feasibility of the algorithm was verified. After filtering the location data, the location information can be obtained.
