Which of the following is NOT a NAVWAR characteristic?

• A. Nav signals are weak and easily jammed
• B. Nav signals are vulnerable to spoofing
• C. Nav signals are immune to jamming
• D. Nav signals operate in specific bands

Answer: (D)

NAVWAR focuses on how navigation signals hold up under adversarial conditions: their susceptibility to interference, spoofing, and jamming, and the fact that they are not immune to such threats. Statements that the signals are weak and easily jammed and that they are vulnerable to spoofing describe these vulnerability aspects, which are core to NAVWAR concerns. Saying they are immune to jamming would be contrary to NAVWAR realities. The idea that nav signals operate in specific bands, however, is a matter of spectrum allocation and design, not a vulnerability or resilience characteristic described by NAVWAR. So, this band-specific attribute is not a NAVWAR characteristic, making it the statement that does not fit NAVWAR’s focus.
