GPS provides two levels of service - ________ (SPS) for civilian users, and ________ (PPS) for military users.

• A. STANDARD POSITION SERVICE and PRECISE POSITION SERVICE
• B. STANDARD SERVICE and PRECISE SERVICE
• C. STANDARD NAVIGATION SERVICE and PRECISE NAVIGATION SERVICE
• D. GLOBAL POSITIONING SERVICE and NAVSTAR SERVICE

Answer: (A)

GPS provides two levels of service: Standard Positioning Service for civilian users and Precise Positioning Service for military users. The civilian open service is designed for general use and provides reliable positioning with standard accuracy, while the military service is restricted and encrypted to deliver higher accuracy and security features, such as anti-spoofing protections. The names in the correct choice–Standard Positioning Service and Precise Positioning Service–match these official designations. The other options mix up or omit key terms (for example, missing “Positioning,” using generic “Standard/NAVSTAR” wording, or pairing brand names rather than the actual service labels), so they don’t accurately describe the two GPS service levels.
