The geostationary belt looks orderly from the ground — satellites parked at fixed longitudes, serving fixed regions. But maintaining that apparent stillness requires continuous propulsion against a set of forces that would otherwise move every satellite off its assigned position within weeks.
Several physical forces continuously perturb GEO orbits, requiring active correction.
Operators don't hold satellites to a single point — they maintain them within a defined 'box' around the assigned longitude.
GEO station-keeping burns are small and frequent — their TLE signatures are subtle but detectable.
The apparent stillness of geostationary satellites is the product of continuous propulsive effort. The moment that effort stops, the physics of the perturbed GEO environment reasserts itself — and what was a fixed communication asset becomes a drifting debris hazard.
