## FAQs
### Q: What is GPS-III SV02's role in the GPS constellation?
A: GPS-III SV02 is a Block III satellite enhancing the Global Positioning System, improving navigation accuracy and signal strength for U.S. and allied users.

### Q: Who manufactured and launched GPS-III SV02?
A: Lockheed Martin Space manufactured the satellite, while United Launch Alliance provided the Delta IV Medium+(4,2) launch vehicle.

### Q: How does GPS-III SV02 differ from earlier GPS satellites?
A: It belongs to the advanced GPS Block III series, featuring a more powerful signal, increased resistance to jamming, and support for the new L1C civil signal.

### Q: What power systems does GPS-III SV02 use?
A: It relies on two spacecraft solar arrays and a LEROS propulsion system.

### Q: When was GPS-III SV02 deployed?
A: It was launched on August 22, 2019, becoming the second operational Block III satellite after GPS-III SV01.

## Why It Matters
GPS-III SV02 significantly modernizes the U.S. GPS constellation by delivering three times greater accuracy and eight times improved anti-jamming capabilities compared to legacy satellites. It introduced the new civil L1C signal, compatible with international systems like Galileo and QZSS, fostering global interoperability. As part of the $13 billion Block III program, it directly enables critical applications—from military precision targeting to civilian aviation—while setting the stage for the next decade of space-based navigation.

## Notable For
- **Second Operational Block III Satellite**: Following GPS-III SV01, it expanded the modern GPS constellation.
- **First Civil L1C Signal Transmission**: Enabled compatibility with non-U.S. navigation systems.
- **Enhanced Anti-Jamming**: Delivered eight times greater resistance to signal disruption than legacy satellites.
- **High-Power L-Band Signal**: Provided three times stronger civilian navigation signals.
- **Extended Power Systems**: Utilized dual solar arrays and LEROS propulsion for sustained operations.
