What technology is used to determine an aircraft's position on the ground?

The concept here is ground surveillance for aircraft and vehicle movement at an airport. The technology used to determine an aircraft’s position on the ground is the Airport Surface Detection Equipment, or ASDE. ASDE tracks where planes and ground vehicles are taxiing on the airport surface and displays their real-time positions to air traffic controllers. This is crucial for safe taxi operations, hold-short decisions, and avoiding runway incursions, especially in low visibility. Modern systems often go by ASDE-X, which combines radar with other sensors to provide even more precise surface position data. Weather radar and visual observation by controllers or pilots don’t provide reliable ground-positioning data, so ASDE is the appropriate technology.
