Wouldn't that also suit an Earth surveillance array with unprecedented resolution?
- 1letterunixname 3y agoIn general, the smaller the separation, the smaller the synthetic aperture. Precise ranging and relativistic corrections are what permit large scale experiments like LIGO and LISA to work as a device the size of the complete aperture.
