METHOD OF ADJUSTING AND TUNING TOPOGRAPHIC PRECISE POSITIONING AND NAVIGATION SYSTEM EQUIPMENT Russian patent published in 2014 - IPC G07C3/00 G05B23/00 

FIELD: physics.

SUBSTANCE: method involves assembling the article to be tuned, adjustment thereof and using a sample (reference) article. Before tuning and adjustment operations, quality assessment criteria are determined, said criteria being a function of distribution of adjustment errors of the topographic precise positioning and navigation system or distribution of its output parameters based on the set tolerance limit; the tuning and adjustment process is broken down into a series of simple operations with pre-adjustment separate assembly units; adjustment is carried out on installations on measuring devices or by comparing the article to be adjusted with a reference sample (electrical drawing method). The process of adjusting the equipment is broken down into a series of steps, the first step involving shaking the article on a vibration stand in order to remove foreign objects and detect loose joints, the second step involving checking correct assembly based on pre-plotted maps and tables, covering all circuits of the checked device, the third step involving checking operating modes of microcircuits and semiconductor devices, the fourth step involving checking functioning of the device overall and performing adjustment to obtain given characteristics with further control of criteria of the quality of the topographic precise positioning and navigation system executing assigned tasks in conditions comparable with real operating conditions.

EFFECT: high quality of tuning and adjustment operations.
