Abstract

Configuration of a network and observation weights plays an important role in designing and establishing a geodetic network. In this paper, we consider single- and multi-objective optimization models in some numerical investigation. The results illustrate that the reliability model yields the best results in view of internal and external reliability and achievable observation precision. This result we interpret as that the reliability criterion is more sensitive to the configuration of a network than any of the other criteria. We propose re-optimization of the network in the cases where very high (non-achievable) precision is required or when some conditions are not met in the optimization process.
