A new method of high-energy gamma ray incident direction reconstruction is
developed for gamma-ray detectors with multilayered converters. The method uses
data from converter and, if available, from position-sensitive calorimeter to
reconstruct an electromagnetic cascade axis and to determine the incident direction
of a primary gamma. For the first time to find point of intersection of gamma
direction line with a convertor plane, the median of energy deposit in sensitive
plane of a convertor is used. Applied, for example, to space gamma-telescope “GAMMA-400” this method allowed to achieve the angular resolution ~ 0.01° at gamma-ray energy of 100 GeV, being much better than accuracy of the past and present space-
and ground-based experiments. In the algorithm presented, a trade-off between the
angular resolution and the effective area can be found to meet scientific goal of an
