#4 Precise Positioning in The Sea with Jürgen Rüffer, ALLSAT GmbH

<p>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. <br/>Jürgen Rüffer is a geodesist, a surveying expert and much more than that.</p><p>But where do you actually need surveying at sea? Well, if you&apos;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. </p><p>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.  </p><p>www.allsat.de<br/>www.baerbel-fening.de<br/>www.maritime-technik.de</p>
