dc.descriptionIn this letter we reexamine the evaluation of \zone in some proposed tests of relativistic gravitomagnetism with existing and proposed laser--ranged LAGEOS--like satellites in the gravitational field of the Earth. A more conservative and realistic approach is followed by using the diagonal part only of the covariance matrix of the EGM96 Earth's gravity model up to degree l=20. It turns out that, within this context and according to the present level of knowledge of the terrestrial gravitational field, the best choice would be the use of a recently proposed combination using the nodes Ωof LAGEOS, LAGEOS II and LARES and the perigees ωof LAGEOS II and LARES. Indeed, it turns out to be insensitive both to the even zonal harmonics of degree higher than l=20 and to the correlation among them
