Abstract:

When estimating precision geodetic control network design, people may use the preset formula, in which medium the angle error according to norms, important components of the islands reflected structural diagram has been idealized and chemical formula is also approximated. So if you use this formula to estimate the network was measured in the field, it will no longer true. The contents of this article has surveyed formula approximate estimate accuracy some characteristic triangular network, from which to draw conclusions about the case applies and recommendations.
