Sentinel's capability to operate under various weather and lighting conditions is...

• A. Daylight-only
• B. All-weather/day-night operation
• C. Nighttime-only
• D. Fog-only

Answer: (B)

Sentinel’s capability to operate under various weather and lighting conditions means it provides all-weather day-night operation. This is because its sensing methods—primarily radar and other non-visible-light channels—are not dependent on ambient light or clear weather. Radar can detect and track targets through rain, fog, dust, and darkness, enabling continuous 24/7 coverage. In contrast, daylight-only or nighttime-only operation would limit performance under half the conditions, and a fog-only capability doesn’t reflect the system’s capability across the full range of weather and lighting.
