Question
How many NAVSTAR GPS satellites in standard constellation are operational and provide uninterrupted service?
The correct answer is
24
GPS Constellation Size
The standard NAVSTAR GPS constellation is designed to have a specific number of operational satellites to ensure continuous global coverage and uninterrupted service.
Operational Satellite Requirement
A minimum of 24 operational NAVSTAR GPS satellites are required in orbit to provide uninterrupted service worldwide. This number ensures that at least four satellites are visible from any point on Earth at any given time, which is necessary for accurate positioning, navigation, and timing (PNT) services.
Understanding Constellation Design
- The GPS constellation is structured with satellites distributed across multiple orbital planes.
- This strategic placement guarantees redundancy and global coverage.
- Having 24 satellites ensures that even with occasional maintenance or satellite failures, the network can still provide the necessary PNT services without interruption.
