What feature makes the DAGR more resistant to jamming compared to commercial GPS receivers?

• A. It uses higher power signals
• B. It has wider frequency ranges
• C. It includes a backup power source
• D. It operates with fewer satellites

Answer: (B)

The correct choice highlights that the DAGR (Defense Advanced GPS Receiver) is designed with advanced capabilities that enhance its resilience against jamming. Specifically, its ability to operate across wider frequency ranges allows it to utilize multiple signals that can help mitigate interference from jamming attempts. In military applications, jamming can severely disrupt navigation systems. By using a broader frequency spectrum, the DAGR can maintain functionality even when certain frequencies are being targeted and jammed by adversaries. This adaptability makes the DAGR a significantly more robust option for military navigation compared to commercial GPS receivers, which typically operate on more limited frequency bands and are thus more vulnerable to targeted jamming. Understanding this distinction is crucial, as it illustrates why military technology often incorporates more complex and versatile features to ensure reliability in challenging operational environments.
