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).

Our SONAR Simulator Supports Underwater Speech Communication Now

Due to the work of Owe Wisch and Alexej Namenas (and of the rest of the SONAR team, of course) our SONAR simulator supports now a real-time mode for testing underwater speech communication. A multitude of "subscribers" can connect to our virtual ocean and send and receive signals. The simulator consists of large (time-variant) convolution engine as well as a realistic noise simulation that ...
