Geodesy is the science of accurately measuring the geometric shape of the earth, its orientation in space, and its gravity field, and monitoring how these properties change over time. Space geodesy is the geodesy that is practiced using extra-terrestrial assets such as satellites and quasars.
Haystack scientists and engineers focus on two aspects of space geodesy: geodetic VLBI, or measuring positions on the earth and the earth’s rotation and orientation, and polar geodesy, or measuring polar ice in the Arctic and Antarctic.
SGIP: Antarctic Seismo-Geodetic Ice Penetrator
Monitoring the response of ice shelves in Antarctica to ocean forces.
The Haystack VLBI Geodetic Observing System (VGOS) signal chain has been in development since 2007 and in service since 2010. It was developed for NASA and has been installed in Texas and Hawaii.
