Abstract: This paper provides a simple and accessible derivation of the inner constraints for 3-D survey networks. There are three positional constraints, three rotational constraints, and one scale constraint. These constraints are often used in minimally constrained free net adjustments where error ellipses reflect the geometry of the network rather than the arbitrary imposition of constraints.
