In particular, he studied several aspects of the measuringements of the general relativistic [[frame-dragging]] effect with artificial spacecraft, natural satellites, planets and stars orbiting different types of bodies.<ref>

}}</ref> In this context, he performed detailed analyses of several potential sources of systematic biaerrors which may have an impact on the total accuracy of many performed and proposed tests of such a subtle effect predicted within the framework of [[general relativity]]by [[general relativity]] which have been either proposed or actually performed. Another line of research pursued by L. Iorio wais the possible existence of the [[Pioneer anomaly]] as a genuine gravitational phenomena.on<ref>

}}</ref> Indeed, if it was really due to an external gravitational cause, also the orbital motions of the major natural bodies moving in the spatial regions in which the [[Pioneer anomaly]] was detected should be affected as well in the same way. Iorio studied also the phenomenology of various [[several modified models of the gravity]] likeational interaction such as, e.g., the [[DGP]] braneworld model.<ref>
