The main sources of errors of coordinate information of strapdown inertial navigation systems (SINS) are considered. The requirements to the errors and instabilities of laser gyroscopes as primary information sensors of SINS of the 1-3rd accuracy class are analyzed. An algorithm for selecting laser gyroscopes for precision navigation measuring systems is proposed taking into account the design and accuracy characteristics of a specific laser gyroscope. This approach was tested during experimental studies of the GL-2D device. The test results confirmed the possibility of using GL-2D in the development of SINS of the 2nd accuracy class for solving precision navigation problems by land and aviation objects.
