We construct a single smooth orthogonal projection with desired localization whose average under a group action yields the decomposition of the identity operator. For any full rank lattice, a smooth projection is localized in a neighborhood of an arbitrary precompact fundamental domain. We also show the existence of a highly localized smooth orthogonal projection, whose Marcinkiewicz average under the action ofSO(d), is a multiple of the identity on. As an application we construct highly localized continuous Parseval frames on the sphere.
