One could think of satellite handover as inter-satellite handover or intra-satellite handover, and intra-satellite handover can be thought of as if you have changed from one part to the other or intra-spot handover.
Satellite handover can be described in terms of inter-satellite handover, and intra-satellite handover and intra-satellite handover can be again bifurcated in terms of inter-spot handover and intra-spot handover.
