    • 數據廣播系統(RDS)是一個發展超過20年的成熟系統, 基於FM無線電的普遍使用、低成本需求與廣播的便利性, RDS適合使用於大範圍與低載量資料的無線傳輸。本論文中提出了RDS系統在為輕航機所設計之數位航電儀表系統(EFIS)上的應用。地面監控站上即時的監控資料可以經由無線傳輸被傳送到輕航機上的RDS接收器。因為低建構成本的RDS 廣播站與廣泛的RDS接收器應用,RDS在輕航機EFIS發展計畫上的GPRS監控系統中扮演的是一個備援的角色,本論文所提出的RDS應用是建構在EFIS上,經由多次的測試能驗證並支持這個設計的可行性。

    Radio Data System (RDS) is a mature technique which has been developed over the past 20 years. Due to the common use of FM radio, the traits of low estate requirement and the convenience in broadcasting, RDS is suitable for using in wireless transmission of large-range and low-load data. This article proposes the application of RDS in the Electronic Flight Instrument System (EFIS) of Ultra Light Aircrafts. The real time surveillance information from the airport control center of ultra light aircrafts can be wirelessly transmitted to the RDS receiver in the aircrafts. Because of the low-price of RDS broadcast station to widespread receiver application, the RDS is used as a redundant system to GPRS surveillance for ultra light aircrafts on the electronics flight instrument system (EFIS) developing project. The proposed RDS application is established onto EFIS with verification tests to support the designed capability.
