Welcome to this podcast episode in which I talk to engineer Jürgen Rüffer. He is the managing director of ALLSAT GmbH in Hanover, where everything revolves around surveying. 
Jürgen Rüffer is a geodesist, a surveying expert and much more than that.

But where do you actually need surveying at sea? Well, if you've ever seen an offshore installation from the air, you might have noticed that the individual wind turbines are lined up like on a string of pearls, very precisely. 

How do you measure something like that? How accurate can you get with GPS data, for example?  Not that accurate, says Jürgen Rüffer, only to within 1 meter. However, he manages to determine the location of an offshore wind turbine with centimetre accuracy.  He will explain to us how this works in the course of this podcast episode.
