Abstract

Quality analysis of GPS aerial triangulation has only been partially performed so far. Extensive theoretical and empirical accuracy and precision investigations have been carried out. However, reliability, the other aspect of quality, has received almost no attention. For this purpose, under the usual independence assumptions, no new theory is required. All that has to be done is to compute redundancy numbers, controllability factors and sensitivity factors. These parameters have been computed for 20% and 60% sidelap simulated block configurations. The results indicate that the introduction of aerial control makes aerial triangulation even more reliable than before. The paper also discusses the use of trajectory control as a generalization of aerial control points.
