Description: The article deals with the issues of using free-of-charge platforms of inertial navigation systems based on the use of MEMS-sensors, ring-shaped laser and fiber-optic gyroscopes for perspective systems high-precision weapons. Examples of the use of new sensors in US HPW samples are given: GMLRS (guided multiple launch rocket system), Army TACMS (army tactical missile system), SAM PAC-3, SAM THAAD, improved position determining system for MLRS M270А1. Analyzes the technical characteristics of the sensors and their cost. Examples of the use of new sensors integrated with the satellite navigation system in the ISKANDER-M and TORNADO-S missile control systems developed in Russia are given. Consideration is being given to the development of the Ukrainian companies «Khartron-Arkos LTD» and «Arsenal» of a free-form inertial navigation system for the advanced missile system «Grom-2». As one of the most important directions in the development of positioning systems, the inte-gration of free-form inertial navigation systems with GPS and GLONASS satellite navigation systems is considered. The article concludes that using satellite navigation systems as a means of positioning makes it possible to obtain fairly cheap high-precision weapons, which greatly increases the risk of such weapons being used by terrorist groups. However, the experience of combat operations in Syria has shown that the use of such systems is possible mainly in local conflicts in opposition to armies not equipped with modern EW systems. In this connection, when creating promising samples of the HPW, the emphasis is on the integration of positioning tools of various physical nature. The main problem of the development of high-precision weapons of the 5th generation is the possibility of their effective combat use only in conjunction with modern reconnaissance, communica-tion and navigation systems. The use of the HPW outside such systems leads to a decrease in its effectiveness to the systems of the 4th generation.
