FIELD: geodesy.
SUBSTANCE: invention relates to geodetic instruments, namely to instruments for taking readings when performing tacheometric survey of pipes in horizontal position, and can be used for assembly of walking excavator boom. Device for tacheometric observations, including a landmark with a magnetic tip and a reflector, further has a U-shaped housing, thickened in the central part of the crossbar, two legs which are symmetric with respect to the vertical axis and which are support elements having rounded magnetic elements at the ends, and the pole is installed in passing through thickened central part of body through hole, with possibility of translational movement, wherein one end with magnetic sharp tip is located in middle between support elements, and on second, extending outward from above, reflector is installed and fixed, wherein the housing has cylindrical levels, one of which is parallel to the pole, and the other – at a right angle to it.
EFFECT: technical result is that it is possible to determine the location of the axis, take a count, id est obtaining coordinates of points, which means accurate connection of pipes.
