Anchor: #i1000138Summary
Network design includes: 1.) the determination of the number and location of existing control stations for network constraints; 2.) the selection of new project control stations, and 3.) the relative dispersion of network observations.
Network design has relevance for concerns regarding the elimination and/or reduction of potential error sources, as well as for providing adequate ties to the existing geodetic reference system (NAD83). These concerns may be addressed by the choice of which existing control stations should be included, as well as the planning of the new station locations and network observation periods. GPS derived orthometric heights are particularly sensitive to the distribution of observations and network constraints.
