Abstract :
Six terrain stochastic linearization techniques are discussed. Among them are three new ones which were developed for TAN (terrain-aided navigation). These three are the improved full-plane fit (IFPF), the mean tangent-line (MTL), and the two-subgroup fit (TSF) techniques. Performance evaluations for each technique are made and compared. The evaluation for each technique makes use of six measures. Each technique has its merits and demerits. On the whole, the TSF technique appears to be the best
