中文摘要 隨著時代的演進,擁有嶄新訊號結構的現代化全球導航衛星系統(GNSS)在過去十年間迅速的發展。第一顆GPS Block IIF型號衛星已於2010年發射並開始傳送新的L5訊號,在擁有更長的電碼長度與更快的電碼速率的優勢下,能獲得更佳的定位準確度。本論文提供了一個可以對GPS L1/L5雙頻實際訊號後處理的程式架構,並實現從訊號的擷取、追蹤到定位的完整流程。由於目前播送L5訊號的新衛星數量仍不足以單獨定位,文中將以L5的觀測量來協助L1進行定位與消除誤差,以期獲得更好的結果。由於GNSS軟體接收機在處理不同頻率或型式的訊號上,擁有較高彈性與可重複定義的優點,本論文也因此採用兩個軟體無線電平台USRP 來進行同步的雙頻訊號的接收。台灣地處東亞地區,是日本的區域型衛星準天頂系統(QZSS)覆蓋範圍,該衛星發送包含GPS L1、L5與類星基增強系統訊號L1-SAIF,也都納入本論文的探討範圍。此外,由於電離層的的影響一直是GNSS的量測誤差重要的一環,如何估測與消除此項誤差也成為一個重要議題,本文也將探討使用GNSS觀測量來進行電離層相關的誤差估測與修正。
英文摘要 Over time, the modernized Global Navigation Satellite System (GNSS) with the improved signal structure arose and was realized at the last decade. In 2010, a Block IIF GPS satellite was launched and started to broadcast the signal on L5 band. The higher chipping rate and longer spreading code is used in this new satellite for the better accuracy. This thesis presents a dual frequency software procedure for post processing real data of the GPS L1 and new L5 signal. The detail algorithm from acquisition, tracking and combined positioning is realized. Due to the number of satellite that equip with new GPS signal are still insufficient, the positioning experiments are using L5 measurements to assist the L1 for better performance. Since the GPS/GNSS software receivers have been popular these years due to its flexibility and re-configurability while dealing with different types of signal. The implementation of the dual frequency receiver is by means of using two synchronized software radio platforms called Universal Software Radio Peripheral (USRP). The Japanese Quasi-Zenith Satellite System (QZSS) which broadcasted GPS signals on both L1 and L5 band is also considered in the experiment, including its SBAS-like signal L1-SAIF. Furthermore, owing to one of the main measurement error in GNSS is caused by Earth ionosphere, the estimation and elimination of this error can be an interesting issue. Thus, some discussions of ionosphere error estimation using GNSS measurement, QZSS L1-SAIF and IGS data are also present.
