Gyromat
Gyromat is the name of a high-precision surveying gyro that was developed in 1978 in Bochum by the Westphalian Mining Union's Office for underground surveying of mines .
While surveying gyros had an accuracy of ± 0.003 to 0.01 gon and required an observation time of the gyro axes of around a quarter of an hour, the measuring system of the Gyromat was automated and the accuracy increased to a few arc seconds .
The Gyromat's distinguishing features are the reduction in mechanical gyro drift and the precise mathematical modeling of the remaining drift errors . The automation not only enables the measurements to be significantly shortened, but also relieves the mine surveyor in his work underground.
Today DMT is the manufacturer of the Gyromat.
