SELF-ALIGNING LEVELING INSTRUMENT

摘要

geodetic instruments, optical leveling geodetic levels. SUBSTANCE: given leveling instrument has optical system completely free of technological errors with digital reading of altitude excesses displayed on screen that can be recorded by printer in case of necessity. Internal photoelectric reading unit insensitive to technological errors of optical system can be inserted in self-aligning leveling instrument, television and automatics can be employed also. Technical achievement of proposed invention lies in leveling without geodetic rack, in sighting and observation on TV screen of video control unit distant from leveling instrument at any range convenient for observer. EFFECT: improved functional capabilities of self-aligning leveling instrument. 1 cl, 1 dwg
