Article devote to development measures which can allow in a further take advantage azimuthally nozzle ANB-1 perisscope surveying compass, so far as subsequent employment ANB-1 due to finishing century become impossible. According of stars movements research was spot the small b-sector for period from 2000 up to 2050 year.; Also was suggest a new scheme to replace exist reference grate ANB-1; to develop working procedure to replace exist reference grate; developing methodology of using azimuthally nozzle for definition directional angle at night before device’s reference grate replacement.
