KPGO - Kōkeʻe Park Geophysical Observatory

Location of KPGO on a globe

KPGO hosts three of the four geodetic techniques:

  • Global Navigational Satellite System (GNSS): KPGO hosts a Turbo-Rogue GPS receiver with a total of six GNSS receivers, and it is an IGS station.
  • Very Long Baseline Interferometry (VLBI): KPGO currently hosts two VLBI antennas -- a 20-m S/X antenna and a VGOS 12-m antenna. It has hosted additional antennas in the past.
  • Doppler Orbitography and Radio-positioning integrated by Satellite (DORIS): KPGO hosts a DORIS beacon and remote control.

KPGO operations began in 1961. At that time, KPGO was part of the NASA Manned Space Flight Network (MSFN). Since that time, KPGO has supported many NASA and external projects and has hosted equipment from a variety of techniques. KPGO is a highly flexible and useful geodetic site.

The Navy and NASA are jointly preparing an Environmental Impact Statement (EIS) for real estate agreements at PMRF and KPGO
May 08, 2024

The U.S. Navy and the National Aeronautics and Space Administration (NASA) are jointly preparing an Environmental Impact Statement (EIS) to evaluate the potential environmental impacts of proposed real estate agreements with the State of Hawai‘i for the Pacific Missile Range Facility (PMRF) and the Kōkeʻe Park Geophysical Observatory (KPGO). Public involvement is an integral part of the environmental planning process. The public has an important role in providing input during this process to help the Navy and NASA make more informed decisions about the proposed real estate action including potential alternatives, environmental or cultural concerns, information the public would like the Navy and NASA to know, and any other information the public would like to see addressed in the EIS.

Please see this fact sheet and visit the PRMF & KPGO EIS website to learn more about the real estate action, the environmental planning process, or how to submit comments:
