📡 Space VLBI Baseline & Resolution Simulator

Compare a single radio dish, an Earth-only VLBI array and a space-VLBI array with an antenna in distant orbit: watch the maximum baseline and angular resolution change, and see a simulated radio-source image sharpen as the effective baseline grows.

⚙ Under the hood

Compare a single radio dish, an Earth-only VLBI array and a space-VLBI array with one antenna in distant orbit: switch modes to see the maximum baseline and angular resolution change live, and watch a simulated radio-source image sharpen dramatically as the effective baseline grows from a dish diameter to Earth's diameter to hundreds of thousands of kilometres.
