What are the two operational modes of GPS?

• A. Standard Mode and Advanced Mode
• B. Coarse Acquisition (C/A) and P(Y)
• C. Basic Mode and Security Mode
• D. Navigation Mode and Encryption Mode

Answer: (B)

The two operational modes of GPS are Coarse Acquisition (C/A) and P(Y). The C/A signal is the standard GPS signal intended for civilian use, offering a degree of accuracy suitable for basic navigation purposes. It is widely available and utilized in most consumer GPS devices. On the other hand, the P(Y) code is a more secure, encrypted signal primarily used by the military, providing higher precision and robustness against interference. This distinction is crucial because it highlights the different access levels and functionalities provided by GPS signals to various users, catering to both public and military needs. Understanding these modes is essential for recognizing how GPS technology operates based on user requirements and security considerations. The other choices do not accurately represent the established operational modes of GPS and do not involve the specific technical distinctions between civilian and military applications.
