本文介绍了日本如何准备创建一个区域增强系统，即准天顶卫星系统（QZSS），该系统将提供额外的类似全球定位系统（GPS）的信号，旨在提高移动的用户的定位能力，并提供新的通信服务。在这篇文章中，QZSS的成员讨论了拟议的系统设计和预期的好处，以及目前的QZSS概念，设计考虑和替代方案。这包括卫星星座、地面跟踪网络、系统定时和差分校正服务计划。
This article relates how Japan is gearing up to creating a regional augmentation, the Quasi-Zenith Satellite System (QZSS), which will provide additional Global Positioning System (GPS)-like signals designed to improve positioning capability for mobile users, as well as offering new communications services. In this article, members of the QZSS discuss the proposed system design and its expected benefits, as well as the current QZSS concept, design considerations and alternatives. This includes the satellite constellation, ground tracking network, system timing, and plans for a differential corrections service.
