Abstract

Recently, Japan Aerospace Exploration Agency (JAXA) provides Quasi-Zenith Satellite System (QZSS), a regional satellite system covering East Asia and Oceania region. The objective of QZSS is to improve the availability as well as the performance of GNSS system. Besides navigation signals, QZSS also transmits L-band Experimental signal (LEX) for augmentation corrections including orbit and clock information that support Precise Point Positioning (PPP). In this paper, a method for decoding LEX signal is first presented. Next, the availability of the LEX signal and the quality of the broadcasted correction messages for PPP solutions are evaluated in Vietnam. The results of PPP using LEX signal have been compared to those using augmentation corrections from International GNSS service (IGS) in both static and kinematic positioning modes. Experimental results conducted in Hanoi, Vietnam show the feasibility of using LEX signal to deliver high accuracy positioning service to Vietnamese GNSS users.

越南QZSS LEX信号精确点定位评价

最近，日本宇宙航空研究开发机构(JAXA)提供了准天顶卫星系统(QZSS)，这是一个覆盖东亚和大洋洲地区的区域卫星系统。QZSS的目标是提高GNSS系统的可用性和性能。除了导航信号外，QZSS还发送l波段实验信号(LEX)，用于增强校正，包括支持精确点定位(PPP)的轨道和时钟信息。本文首先提出了一种LEX信号的解码方法。接下来，对越南的LEX信号的可用性和PPP解决方案广播修正信息的质量进行评估。在静态和运动定位模式下，将使用LEX信号的PPP结果与使用国际GNSS服务(IGS)增强校正的PPP结果进行了比较。在越南河内进行的实验结果表明，利用LEX信号向越南GNSS用户提供高精度定位服务是可行的。
