Block IIA/IIR IIIA • Increased accuracy (0.63-m spec) • Increased EC power (-151.5 dBW) IIIB • Assured availability • Real-time communications IIIC • Navigation integrity • High-power spot beam
IIR-M: IIA/IIR capabilities plus • 2nd civil signal on L2 (L2C) • Earth coverage M-code on L1 & L2 • L5 Demonstration • Flex power upgrade to defeat low-level enemy
jamming
IIF: IIR-M capability plus • 3rd civil signal on L5
• Basic GPS provides initial navigation capabilities
• Std service (16-24-m SEP) – Single frequency (L1) – C/A code navigation
• Precise service (16-m SEP) – Two frequencies (L1 & L2) – P-code navigation

Airborne platform navigation must be highly precise and requires high-rate GPS data
representation of actual fault ruptures recorded and preserved in unprecedented detail
Terrestrial Laser Scanner is versatile - can scan at
ranges of 200 m
representation of 3D surfaces is extraordinarily detailed; 42 million pts. at Echo Cliffs PBR
Conclusions:
Opportunities Posed by Advances in Geodesy
- GPS (L2C, L5, L1C) / GNSS - ‘new and improved’ signals may offer signficant changes - high-rate and overlap with seismology - real-time, e.g. co-seismic displacements; EEW & tsunami (e.g., Chile) - zipper arrays; co-located GPS and strong-motion instruments
- InSAR
- LiDAR - geodetic imaging - open data formats - software development - artifact removal
- Image Differencing (e.g., COSI-Corr)
