longerbaseline
Longerbaseline is a term used in interferometry and related measurement networks to describe configurations in which the separation between observing elements—such as telescopes, antennas, or sensors—is increased beyond a standard or prior setup. The length of the baseline is a primary determinant of the system’s angular resolution and the spatial frequencies that can be sampled.
In general, the angular resolution achievable by an interferometric array scales roughly with the observing wavelength
Applications span astronomy and geodesy. In radio astronomy, Very Long Baseline Interferometry uses baselines spanning continents
Future developments focus on space VLBI, improved synchronization, and advanced data processing to exploit even longer
