DEVICE FOR POSTING THE SENSITIVITY GRAVIMETER AXIS

Angle measurement means are one of the advanced directions for the application of gas ring lasers. The requirements of ring lasers used in angle measurement devices are different, in many respects, from those used in navigation. A simple ring laser developed for implementation in high-precision angle measurement instruments is described. The main specifications are presented. Methods of the accelerated tests are imperfect for determining a term of storage; therefore, tests during a real storage term remain the most reliable. Operation of the ring lasers in angle measuring instruments during 20 years has demonstrated their high stability. Using the described ring laser the angle measurement means of accuracy that exceeds an accuracy of the existing National Standards for a plane angle can be developed.
