This EXPRO+ procurement is part of the NAVISP Programme, under Elelment 1, Work Plan 2017.This activity aims to explore the use of two-way ranging for radionavigation, to overcome the some of the shortcomings of passive ranging systems such as GNSS. Prominent amongst these shortcomings is the fundamental vulnerability of passive-ranging systems to malicious compromise via spoofing or meaconing. Rather than operating on the principles of time-of-arrival ranging, the proposed research will define a new scheme that will form ranging estimates based on infrastructure interrogation, using cryptographic distance-bounding techniques, thereby firmly asserting the validity of the channel estimates. Unlike the loose concept of security that can be offered via cryptographically enhanced GNSS signals, the proposed demonstration will derive position estimates based on provably secure observations.
