"Hi Burkhard.

Awesome project! Where did you find the specification on the intelliducer? I am looking for at similar sonar unit for seafloor mapping around wrecks, but a resolution of 1m below 10m in simply not sufficient. Does the unit output…"

"I will look into this in the evening. :)"

"I am using an accelerometer instead of thermopiles, so my sensor file is altered as well. You should be able to use thermopiles, just keep track of the roll (sensor_roll?) and pitch (sensor_pitch?) variables.
 
The changes in the GPS code is only…"

"For some reason you received floats on your serial channel? Since a float can not be parsed by Integer.parseInt the code fails. I would look into the print functions in the ardupilot code.
The received values should look something like this:…"

"Actually I think you could just use the GPS and print functions, if you have a working setup yourself."

"Hey guys.
 
The trick is to not mess up the data stream from the GPS module, since only one serial port is available. I created a command queue in the ground station, so it transmits one command after each GPS message. These are only received every…"

"Very well written report, and LaTeX ftw!
 
I have not had the time to confirm your results, but they seem reasonable at first glance.

"Once again good post Harald.

I would like to see more depth maps, if possible.

Best regards
Niklas"

"No, as far as I have know, the only buggy reading was in the ground course. The rest should work correctly."

"That's right Jason. Actually a unsigned integer would do the job. As far as I know there isn't a way to use a union to produce a three byte number. The easiest thing is just to use the long union, from already existing code. And just set the two…"

"Your system sounds a bit overkill to me. Check out the posts on "Ardupilot goes into the water". That project is very interesting."

"Hi Jack.

Just a small comment on the neural network you are using. Feed forward networks are excellent for prediction of future values, but you should consider the number of nodes in the hidden layer. Usually a large number of hidden nodes, i.e.…"
