Abstract	We present the ATLAS implementation of the generic track-based alignment framework. Being modular and highly configurable it is applicable to all tracking systems of ATLAS: silicon and drift tubes if the Inner Detector as well as the gaseous Muon System. The implementation of the common parts and virtual interfaces is separated from the detector system specific parts. We summarize the implemented formalism of the alignment based on the least squares principle and present the general layout of the software implementation within the Athena framework.
