On July, 19th we christened our (first) small ship. It got the name "MISSy", which stands for "MIMO SONAR System". We did this at the "Kitzeberger Strand". Beside having a small party due to the event, we also did several measurements. One of them was testing a first version of our underwater telephone system. One subscriber was located at the pier, while the second one were Thorben and Alexej cruising with MISSy about 100 to 200 m in front of the pier. We had quite good signal quality, even when operating in so-called full-duplex mode (both subsribers can talk simultaneously). Several people tested the phone - even very young ones, as you can see on the picture.
Thanks again to all people who helped us to let MISSy see finally the water (Matthias, Martin, Dietmar, Jan, and all the others).
