Surveying system for the laser-tracker-based determination of coordinates of points of a surface which are to be surveyed, having ∘ a measurement aid (2, 2', 2") for sampling the points of the surface which are to be surveyed, in particular a laser scanner, comprising oan inertial measurement unit, IMU, for determining movement data of the measurement aid, oa reflector, and oa plurality of measurement aid markings (5, 5', 5"), the plurality of measurement aid markings being arranged in a determined position relation with respect to one another and so as to form a pattern on the measurement aid, so that by using the surveying system, a position can be determined by means of the reflector and an orientation of the measurement aid can be determined by means of the measurement aid markings, o a distance measurement module, o a beam module for variable-direction emission of acquisition radiation, o an alignable measurement aid acquisition unit, which is communicatively connectable to the measurement aid and has an acquisition field of view, the measurement aid acquisition unit being configured to ∘acquire and track the measurement aid on the basis of acquisition radiation reflected by the reflector, ∘acquire the measurement aid markings, and ∘determine coordinates of the points of the surface which are to be surveyed, on the basis of ▪ the acquisition and tracking of the measurement aid, ▪ the acquisition of the measurement aid markings, ▪ a distance to the measurement aid, determined by means of the distance measurement module, and ▪ the sampling by the measurement aid of the points of the surface which are to be surveyed, characterized in that o the measurement aid acquisition unit is furthermore configured to determine coordinates of the points of the surface which are to be surveyed, on the basis of measurement aid movement data determined by the IMU, and o the surveying system is configured to align the measurement aid acquisition unit on the basis of measurement aid movement data determined by the IMU, in such a way that the reflector is inside the acquisition field of view. ∘ a measurement aid (2, 2', 2") for sampling the points of
