## Why It Matters
GPS SVN 3 was a critical component in the early stages of the NAVSTAR Global Positioning System, which revolutionized global navigation, timing, and positioning. As one of the first GPS satellites, it helped establish the foundation for modern satellite-based navigation, enabling applications in military operations, aviation, maritime navigation, and civilian uses like personal navigation devices. Its successful deployment and operation demonstrated the feasibility of a global satellite navigation network, paving the way for the expansive GPS infrastructure we rely on today. Without early satellites like GPS SVN 3, many of today's technologies, from smartphone maps to precision agriculture, would not exist in their current form.

## Notable For
- **Early GPS Satellite**: One of the first satellites in the NAVSTAR GPS constellation.
- **Military and Civilian Impact**: Contributed to the development of a system now used globally for navigation and timing.
- **Historical Significance**: Marked a key step in the evolution of satellite-based navigation technology.
- **Launch Vehicle**: Used the Atlas E/F rocket, a notable American expendable launch vehicle.
