Abstract:

With respect to the widely use and important position of the global navigation satellite systems (GNSS), protection for it is of vital importance. This paper presents a multi-attribute tradespace exploration (MATE) based design method for protection of GNSS. The method comprises four phases. In the first phase, the mission needs and GNSS performances that the decision-makers preferred are defined and specified with attributes. In the second phase, the attributes are inspected and various design variables (i.e. protection means) are proposed. In the third phase, models are built to link the protection means to attributes and costs. In the fourth phase, tradespace analyses are made, and all the designs are analyzed in the same tradespace here. As proved by empirical results, its advantages of analyzing multi-attribute of all the designs in the same tradespace can provide comprehensive foundation for system design and evaluation.
