Zeroizing P Codes will impact which aspect of the mission system?

• A. Mission system accuracy
• B. Encryption integrity
• C. Communications bandwidth
• D. Sensor calibration

Answer: (A)

The important idea is that P codes on GPS provide higher-precision positioning and timing, along with protection against spoofing. If P codes are zeroized, the system loses access to the encrypted, high-precision signals and must rely on the less precise signals, so the navigation solution becomes less accurate. In mission systems, accurate positioning and timing are foundational for navigation, timing synchronization, and coordinated operations, so removing the P code capability directly degrades overall mission system accuracy. While encryption protection would also be affected by the absence of P codes, the primary operational impact emphasized here is the drop in accuracy rather than the cryptographic aspect.
