Background. The experience of research and development of wave solid-state gyroscopes (WGG) in the Russian Federation in comparison with similar foreign experience does not differ in a variety of techniques, among which the main place is occupied by the solution of the problems of mechanical balancing of resonators, which has proven to be an unproductive and unpredictable procedure. Along with this, it is a well-known fact that the modern HHG is controlled by four systems of automatic control of vibration energy, compensation of angular velocity, quadrature and phase. A generalized criterion for assessing the required quality of operation of these systems is the achievement of the established values of the drift characteristics of the HTG. As a rule, the terms of reference for their development set the required values of the random walk of zero σARW [° / √h] and zero stability b [° / h] without reference to estimation methods, despite the fact that σARW and b are included only in the nomenclature parameters estimated by Allan variations. Materials and methods. Allan's method of variations  is recognized by its developer as an alternative to the well-known methods of classical analysis of variance, which have certain limitations in assessing drifts. Along with this, when VTG GE 006 entered the market, it was necessary to face the skeptical attitude of the consumer towards the Allan method without specifying any compelling reasons for such distrust. Results and conclusions. It’s given the purpose of this article is to justify the choice of the method for assessing the drift characteristics of the HTG GE 006 on examples of a comprehensive analysis of samples obtained in long and short runs using two drift models - Allan variations and classical analysis of variance.
