Abstract

This article examines convergence of new algorithm of navigation parameters definition on the basis of photographic image developed by author. It is founded that this algorithm based on Newton numerical method is stabile in meaning of solving convergence in particular area of initial datasets only (when the touchdown point is not too far away or too close). Two ways of modification developed algorithm are proposed for problematic areas of initial datasets. The second one is guarantee convergence for whole range of initial datasets.
