“…Zeeman LG produced by "POLYUS" is presented in Fig. 3 [3,19]. The most important condition for achieving LG stable operation and high precision characteristics, including super-high stability of the scale factor, is to ensure the constancy of the laser cavity length so that the ring laser generates on the single mode.…”

“…The main means to ensure the high quality of LG (Fig. 3) are the installation of new fast and automatic test equipment, simulation of LG behavior under the influence of the environment factors to reduce the time of real tests in development and production [3,[9][10][11]. Our next investigation is devoted to way of using computer simulation of the ring laser resonator length control system to reduce times of technological step of LG production with getting data for sorting LG on accuracy and ability of long-term singlemode operation.…”

Laser strapdown inertial navigation system has become the mainstream of the medium and high precision inertial navigation systems, and its core component is a laser gyro (LG) [20,23].The LG have the advantages of high precision, large dynamic range, fast starting, super stable scale factor, strong environmental adaptability, high reliability and long working life [1,13,18].Apart from Russia, only four countriesthe United States, France, China and Israelhave been able to master the complex knowledge-intensive technology of laser gyros production [13,23,24].Even though the new types of gyros appeared, but the LGs still keep the highest market share and are largely used in navigation and guidance systems. As it is seen in Fig. 1 [24], LGs occupy the highest accuracy zone with bias instability about 0.01 °/h and much less.

In the paper, we consider the ways to improve the quality and economic efficiency of development and production of complex innovative electronic devices, among which are laser gyros (LGs). Development, manufacturing and testing of high-tech LG are relatively expensive. The accurate thermal modeling at the early stages of LG designing is an effective way to reduce overall costs owing to noticeable savings of expenses on multiple-laboratory tests of the LG under development and its re-design due to overheating. Use of the inexpensive Russian computer system ASONIKA for thermal modeling provides yet another boost to cost efficiency. In the paper, details of application of the electro-thermal analogy method, finite difference method, grid method, graph method in ASONIKA are described. The developed algorithm of creation of LG thermal model with the procedure of step-by-step disaggregation (zooming technique) is presented. The process of LG modeling by ASONIKA computer system is explained; the created LG thermal model in graphic view and the obtained thermal field of one of PCB in colored view are demonstrated. Electronic components prone to overheating are specified. The paper also presents the results of empirical verification of modeling with actual measurement of temperature by the thermal sensors installed in places corresponding to the model nodes; those measurements confirmed high accuracy of ASONIKA-based simulation.
