【摘要】 PNT体系能力评价是构建PNT体系的一个重要的反馈式参考和指导。PNT体系能力体现为满足最广泛应用需求的程度。由于服务对象的需求多样性、应用场合的分布广域性,以及服务手段的构建多源性,不能简单地用是或否对PNT体系能力的满足程度进行描述。本文以应用要求为最基本的出发点,指出影响PNT体系能力的关键问题,提出了描述PNT体系能力的基本要素和关键要素,从而为PNT体系能力的定量评估奠定基础。更多还原

【Abstract】 The evaluation of the capacities of the PNT architecture is an important feedback reference and guidance to construct PNT system. The capacities of the PNT architecture reflect the degree of meeting the most wide application requirements. The degree of PNT system satisfying the application requirements cannot be described simply by yes or no because of the diversity of user requirements, the broad of application distribution and the multi-source of service means. The key problems which affect the capacities of the PNT architecture are presented. And the basic elements and key elements of representing the PNT architecture capacities are proposed. Moreover, a multi-dimensional presentation space is constructed based on impact factor and capacity coefficient to describe the capabilities of the PNT architecture quantitatively更多还原
