The Laboratory for Geodetic Measurement Techniques has a comprehensive range of classical surveying instruments for a wide variety of surveying purposes, including the necessary accessories. In addition, there is a wide range of state-of-the-art surveying equipment for teaching and research activities, including professional surveying drone systems (UAV, unmanned aerial vehicle).
In the laboratory a large number of supervised practical exercises for students of surveying, civil engineering and industrial engineering and construction and real estate take place every semester. The laboratory equipment is also used every semester for numerous bachelor and master theses as well as for research projects.
A number of surveying test devices are permanently installed in the basement. Special electronic instruments, such as inclination sensors and a high-precision laser interferometer, are available here if required. The measuring cellar also offers a generous open space for variable experiments and stationary investigations under laboratory conditions.
The laboratory is equipped with the latest total stations from Leica, Topcon and Trimble. All devices have cameras and a robotic function. Some of the devices also have scanning functionality (multi-stations).
In addition, the corresponding accessories (reflectors, target plates, tripods, robotic equipment, etc.) are of course available in large numbers.
With this extensive instrumentation, in addition to the standard measurement procedures, integrated measurement procedures (with GNSS, graphic field book, video camera), "one-man measurement procedures", reflectorless measurements and measurements of highest accuracy can be carried out.
.
In the laboratory, GNSS receivers from Leica, Topcon and Trimble are available and can be used with the existing equipment for both static and kinematic measurements. Besides a post-processing evaluation, the devices can also be used with the different real-time services (e.g. SAPOS).
Together with total stations, the GNSS receivers are also used for integrated measurement procedures.
In the laboratory there are "digital" compensator levels from the companies Leica and Trimble, and "analog" compensator levels from Askania, Breithaupt, Fennel, Kern, Leica, Nikon, Wild and Zeiss. Levels also include an extensive range of levelling staffs, including pairs of precision barcode levelling staffs.
The available instruments allow both accuracy classes to be covered for levelling (engineering levelling, precision levelling).
For more extensive 3D capturing, 2 "classic" laser scanners with corresponding accessories such as target spheres and scanner targets are available.
In addition, further 3D measuring systems for industrial applications (Faro Freestyle, GOM Atos, GOM Tritop) or mobile mapping systems (GEOSLAM ZEB1, Leica BLK3D) can be used.
A total of 6 surveying drones can be used in teaching, for final theses or for research projects. They are supervised by the 5-member pilot team of the Surveying Department, which is the holder of the drone knowledge certificate.
The following survey drones are available:
All use an RGB camera as a sensor, with the DJI Inspire 1 additionally equipped with a Parrot Sequoia near infrared camera. The DJI Matrice 300 RTK can be equipped with additional sensors in the future thanks to its design and a special interface.

The following surveying drones are available:
DJI Inspire 1
Topcon Falcon 8
DJI Phantom4 pro
DJI Matrice 300 RTK
DJI Mavic3
All of them use an RGB camera as sensor, whereby the DJI Inspire 1 was additionally equipped with a Parrot Sequoia near-infrared camera. A near-infrared camera (Altum-PT) is also available for the DJI Matrice 300 RTK.

The equipment of the graphic field books / field computers includes tablet PCs and field computers with Windows or Windows CE operating system (Leica, Mettenmeier, Panasonic, Topcon, Trimble). All graphic fieldbooks and field computers can communicate via WLAN or Bluetooth interfaces with different measuring devices and external sensors, so that many flexible applications in research and teaching are possible.
A wide range of installed onboard programs or apps can be used to control the various measuring devices.
In the laboratory there are other devices available which are not listed in the other categories:
The other equipment includes many "little things", but some of them are indispensable for surveying exercises, bachelor or master theses. These include, for example: Measuring tapes, pole straighteners, plumbs, ranging-rods, pole stands, thermometers, barometers, compasses, clinometers, field book frames, radios, safety material (pylons, warning vests, warning signs, helmets), marking material, field umbrellas.
