Abstract

Navigation message is one of the important components of satellite navigation signals, its design will not only influence the system’s performances including timeliness, integrality, flexibility, reliability and extendibility, but also user’s use-cost. Different from other GNSS systems, the BDS system broadcasts not only the basic navigation messages but also augmentation messages including difference and integrity data. In this paper, the design project of BDS wide area augmentation navigation message is analyzed. And the design contents include message parameters, frame structure, data rate, message arranging format and broadcasting orders. On the basic of the designing, the augmentation navigation message’s performances are evaluated. And the evaluation parameters include communication efficiency, parameters’ expressing performances, broadcasting frequency, demodulation performance and signal detection performance. The conclusions can offer theory and engineering guidance for satellite navigation message design, and can apply in the design of BDS system’s wide area augmentation navigation message directly.
