For how many hours per day is GPS available?

GPS, or Global Positioning System, is designed to provide continuous, worldwide coverage for positioning, navigation, and timing services. The system relies on a constellation of satellites that orbit the Earth, and it operates 24 hours a day, seven days a week, regardless of weather conditions or geographic location. This constant availability makes GPS an invaluable tool for navigation at sea, on land, and in the air, allowing users to pinpoint their location and navigate effectively at any time. Therefore, stating that GPS is available for 24 hours is accurate, as it reflects the system's functionality that operates continuously throughout the day and night.
