A minimum of 24 operational Navstar satellites are required for the GPS system to work effectively. These satellites are strategically positioned in orbit to ensure global coverage and accurate positioning for GPS receivers on Earth.
The minimum number of operational NAVSTAR satellites required for global positioning coverage is typically considered to be 24. This number allows for at least four satellites to be visible from any point on Earth, enabling accurate triangulation and positioning. However, to enhance reliability and accuracy, the system often operates with more than 30 satellites in orbit.

The Air Force tries to maintain 30 working satellites, 24 operational and 6 spares. The system can work with 24 operational satellites only.
The full form of NAVSTAR is Navigation Satellite Timing and Ranging. It is a system of satellites developed by the United States for providing accurate positioning and timing information globally.
The first GPS Navstar satellite was launched on February 22, 1978. This was the beginning of the GPS system, which has now grown to include a constellation of over 30 satellites providing global positioning and navigation services.
