The initial phase of planning a geodetic network where the coordinate system and datum are defined. It addresses the datum defect problem by choosing an optimal reference system for the network coordinates before any physical measurements are planned. This mathematical foundation ensures that the subsequent network design, observations, and least-squares adjustments are grounded in a stable, defined space.

Before we start worrying about station intervisibility, we need to finalize the zero-order design and lock in the datum parameters.
