The two-position passive system of radiovision intended for observation over objects in the millimetric range of lengths is considered. For such system the comparative analysis of the offered and the alternative methods of coordinate system mutual orientation and estimation of ranges to objects is carried out. The aim of the work – is a comparative research of the offered and the alternative methods of objects spatial coordinates estimation in the specified system. The method offered earlier as well as the known alternative method of coordinate estimation is considered. Modification of the alternative method is offered. The quantitative characteristics of the algorithms realizing the methods are received. The advantage of modification according to the accuracy of coordinate estimates and high-speed performance in comparison with the alternative method is shown.

Key words: two-position system, passive radiovision, mutual orientation, conjugate vectors, estimation of ranges.
