The number and distribution of stations defining the optimum CTS with accuracy of the order of 1 cm or better are still open question (Boucher et al., 1984, 1988, 1989, Mueller et al., 1982, Paquet et al. 1988). This problem is investigated in this paper.

The optimum CTS’s consisting of different number of VLBI and SLR stations have been chosen from IRIS nets, GSFC88R01 and GSFC88L01 sets of stations according to the criterion of the minimum values of the matrix traces of inverse matrices of normal equations computed from observational equations (1). The number of 10–15 well distributed stations seems to be the sufficient number of stations defining the optimum CTS on the level of accuracy of 1 cm. IRIS nets are compared with other optimum CTS’s.
