The overall goal of this project is to identify technical problems and potential barriers to the exploitation of Global Navigation Satellite Systems (GNSS) in the UK for safety-critical applications. This can be done best through a short, focused and dedicated effort to bring people together. Our aim is to bring together academic and industrial partners from the UK and overseas to focus on GNSS systems operating in different environments and the problems that they encounter.GNSS encompasses all Global Navigation Satellite Systems such as GPS (Global Positioning System) and Galileo. GPS has become a consumer technology and for many applications it is entirely adequate. However, there are a number of systems that require more than accuracy - integrity is vital. Integrity is a term used in the GPS community that refers to knowledge of the reliability of the navigation solution. Guaranteeing the integrity is a tricky problem. Problems that can occur that affect integrity include interactions of GPS signals with the local environment (e.g. buildings) and interactions of GPS signals with the Earth's atmosphere and ionosphere. This project will unite industry, academia and representatives from the GPS user community to identify GPS integrity threats and will form strategies to deal with them in the future.

该项目的总体目标是确定全球导航卫星系统（GNSS）在英国用于安全关键应用的技术问题和潜在障碍。要做到这一点，最好的办法是把人们聚集在一起，做一个简短、专注和专注的努力。我们的目标是将来自英国和海外的学术和工业合作伙伴聚集在一起，专注于在不同环境中运行的GNSS系统及其遇到的问题。全球导航卫星系统包括所有的全球导航卫星系统，如GPS（全球定位系统）和伽利略。GPS已经成为一种消费技术，对于许多应用来说，它是完全足够的。然而，有许多系统需要的不仅仅是准确性，完整性是至关重要的。完整性是GPS社区中使用的一个术语，指的是对导航解决方案可靠性的了解。保证完整性是一个棘手的问题。可能发生的影响完整性的问题包括GPS信号与当地环境（例如建筑物）的相互作用以及GPS信号与地球大气和电离层的相互作用。该项目将联合工业界、学术界和GPS用户社区的代表，确定GPS完整性威胁，并将形成未来应对这些威胁的战略。
