The checking methods of gyrotheodolite stability were proposed. The main factors estimating the stability of gyrotheodolite were determined. They are the stability of the mean value of oscillating, ze
Solid lubricants lead to substantial weight savings relative to the use of liquid lubricant, especially in the weight-conscious aerospace industry. A new PTFE-A
An algorithm has been developed from various exiting techniques, that provides fully automatic cycle-slip detection at the data preprocessing stage. This algorithm, called pair linear combination, ope
