The Hamiltonian formulation of modified dispersion relations (MDRs) allowsfor their implementation on generic curved spacetimes. In turn it is possibleto derive phenomenological effects. I will present how to construct thekappa-Poincare dispersion relation on curved spacetimes, its sphericallysymmetric realizations, among them the kappa deformation of Schwarzschildspacetime, and its implementation on Friedmann-Lemaitre-Robertson-Walkerspacetimes with arbitrary scale factor. In addition we will construct thegeneral first order modifications of the general relativistic dispersionrelation. Afterwards we will use the perturbative MDRs to calculate specificobservables such as the redshift, lateshift and photon circular orbits.
