Abstract:	Inertial navigation methods show a long application history in the fields of aerospace spacecraft and marine technology. However, in recent years the implementation of inexpensive INS for a wider range of applications can be observed. New applications include smart munitions, a wide variety of land vehicle applications, and video camera image stabilization. For these applications it is necessary to use an inexpensive miniature INS which can satisfy required accuracy characteristics. The exclusion of gyroscopes from navigation system architecture reduces cost. However, the absence of gyroscopes leads to the growth of errors in the anguiar orientation of the navigation system. This, in turn, leads to the growth of errors in the determination of vehicle coordinates. Therefore, one of the main problems in the construction of an integrated navigation system which is based on a gyro-free Inertial Navigation System (INS) and a single antenna Global Positioning System (GPS) is the determination of the initial angular orientation and correction of gyro-free INS angular characteristics on the basis of linear navigation parameters (coordinates and velocity) that are obtained from GPS. This paper describes the proposed solution to this problem.
