The baseline length for the Primary Geodetic Network, 3rd order is.

In geodetic networks, the order of the network determines how precise the measurements must be and, consequently, how long the baselines between control points can be. For the Primary Geodetic Network at the 3rd order, the maximum allowable distance between adjacent control points is five kilometers. Short baselines help limit the accumulation of observational errors from instrument biases, atmospheric effects, and refraction, ensuring the network stays within the required accuracy and remains well connected. Distances like fifty, fifteen, or fifty-five kilometers would exceed what a 3rd-order network is designed to tolerate, leading to degraded precision.
