About PMRF and KPGO

The U.S. Navy's Pacific Missile Range Facility (PMRF) is the world's largest instrumented multi-domain training and testing facility. What makes PMRF unique is its ability to simultaneously support surface, subsurface, air, and space operations. PMRF brings about $150 million annually to Kauaʻi County.

NASA’s Kōke‘e Park Geophysical Observatory (KPGO) is located on a remote ridge within Kōke‘e State Park. NASA operates KPGO to collect geodetic data about the Earth’s shape, orientation in space, and gravity. This data supports modern navigation technology such as the Global Positioning System (GPS), spacecraft navigation, and the geolocation of Earth observations.
