Abstract

Within the European Space Agency's (ESA) Space Weather Service Network, the development of performance indicators for the Global Navigation Satellite System (GNSS) has been identified as essential to meet the growing needs of end users for Space Weather information in the field of navigation. This requires a targeted analysis of Space Weather-related disturbances of technical systems and services in the field of satellite-based navigation, considering the growing requirements of all the different users in this domain. The goal of the Space Weather Impact on GNSS Performance: Application Development (SWIGPAD) project is to develop GNSS performance indicators (GPI) based on Space Weather data provided by European research institutes through the ESA Space Weather Service Portal (available at https://swe.ssa.esa.int) with the aim to fulfill representative use cases derived from dedicated meeting with industry and government experts. The application that serves the GPI will provide the user with information about current and expected effects of Space Weather on positioning at their respective location. Additionally, end users in the various GNSS application domains shall be assisted with an overall numerical and graphical estimate of the positioning uncertainty resulting from ionospheric conditions and its evolution over time. The intent of this article is to present the results of the project and the capabilities of the GPI application.

制定缓解空间天气对全球导航卫星系统影响的绩效指标

在欧洲航天局（欧空局）的空间气象服务网络内，全球导航卫星系统性能指标的制定被认为是满足最终用户对导航领域空间气象信息日益增长的需求的关键。这就需要有针对性地分析卫星导航领域技术系统和服务中与空间天气有关的干扰，同时考虑到该领域所有不同用户日益增长的需求。空间天气对全球导航卫星系统性能的影响：应用程序开发项目的目标是根据欧洲研究机构通过欧空局空间气象服务门户网站（可在https://swe.ssa.esa.int)目的是实现通过与行业和政府专家的专门会议得出的具有代表性的用例。为GPI服务的应用程序将向用户提供有关太空天气对其各自位置定位的当前和预期影响的信息。此外，应协助全球导航卫星系统各应用领域的最终用户对电离层条件及其随时间演变造成的定位不确定性进行总体数字和图形估计。本文的目的是介绍该项目的结果和GPI应用程序的功能。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
