IDOP with the change of relative attitude of the intersatellite: (a) the optimal antenna configuration 1 when satellite relative attitudes psi = 0.174 (rad), theta = 0.174 (rad), phi = 0.174 (rad); (b) the optimal antenna configuration 2 when satellite relative attitudes psi = 0.042 (rad), theta = 0.236 (rad), phi = −0.277 (rad); (c) trajectory of satellite relative attitude; (d) IDOPs in the case of satellite relative attitude changing.
