Can inertial navigation make ground-robot swarms real?

Developers are examining whether inertial navigation can support coordinated ground-robot movement when satellite positioning is unreliable or unavailable. Onboard motion sensors can estimate a vehicle's movement without external signals, but errors accumulate over time and make sustained position accuracy difficult, especially across rough terrain. A practical swarm would need reliable relative positioning, obstacle avoidance and communication among vehicles so that navigation errors do not compound across the group. The discussion concerns a possible technical route and its limitations; it does not identify a deployed military swarm, an acquisition award or validated performance figures for a specific system.
