The linear ac response of a pinned vortex system in uniaxial anisotropic superconductors is studied. The physical model for the interpretation of electrical transport experiments in the linear regime with arbitrary angles between the applied magnetic field, the applied current, and the anisotropy axis is provided. In particular, the pinning constant (also known as Labusch parameter) and Campbell resistivity tensors are derived for arbitrary orientations. The applicability to the various tensor quantities of the well-known angular scaling laws for the angular dependence on the field orientation in uniaxial superconductors is commented. Examples of data analysis based on the present results are provided.
