Positioning by Navstar-GPS: Theory and Practice
Introduction
The Global Positioning System (GPS) is a global navigation satellite system (GNSS) that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. The system is maintained by the United States government and is freely accessible to anyone with a GPS receiver.
How GPS Works
The GPS system consists of a constellation of 31 satellites that orbit the Earth at an altitude of approximately 20,200 kilometers (12,550 miles). Each satellite transmits a signal that contains its current position and the time. GPS receivers use these signals to calculate their own position and time by measuring the time it takes for the signals to travel from the satellites to the receiver.
Applications of GPS
GPS is used in a wide variety of applications, including:
- Navigation: GPS is used for navigation in cars, boats, airplanes, and other vehicles.
- Surveying: GPS is used for surveying land and creating maps.
- Tracking: GPS is used to track the location of people, animals, and objects.
- Timing: GPS is used to synchronize clocks and other devices.
- Remote sensing: GPS is used to collect data about the Earth's surface from satellites.
Benefits of GPS
GPS is a powerful tool that has many benefits, including:
- Accuracy: GPS can provide accurate location information within a few meters.
- Reliability: GPS is a very reliable system that is available 24 hours a day, 7 days a week.
- Accessibility: GPS is freely accessible to anyone with a GPS receiver.
- Versatility: GPS can be used for a wide variety of applications.
