This list is by no means exhaustive; however, we hope that someone can help us with additional material to expand this homepage.

The balloon theodolites described here were made available to us by Prof. Dr.-Ing. Wilhelm Heger (Professor for Practical Geodesy and Surveying Instruments) at the Neubrandenburg University of Applied Sciences.
