Semi active sonar guided torpedo Premade Station

I have made a better guided torpedo that has an onboard sonar! Go check it out: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2502595274

This is not part of the Marino torpedo

Soooooooo....

I've finally finished it all. After a few days of thinking and building I can present you my Sonar Guided Torpedo!


Basically it takes the Sonar input, calculates the target GPS Coordinates and Altitude and sends that to the torpedo via Radio, which then uses a depth hold and interception function to guide itself to the target. To give it some light jamming protection, it generates a random number ranging from 0 to 10000 and takes that as radio communication frequency. The torpedo is only limited to what your sonar can do. I may upload a controller for advanced sonar tracking in the future but I did not want to make it too complicated yet. Alternatively, if your sonar does not work, which may happen since Stormworks has some bugs, you can connect a stabilised camera to a composite input on the Launch Station Controller.


You put the Launch Station Controller on the vehicle you want to launch the torpedo from and hook everything up. The same goes for the torpedo. Torpedo Main Controller and Terminal Phase Controller are placed on the torpedo you are using. Lastly, you build one Torpedo Tube Controller for each torpedo tube you have. All logic nodes are labelled and some described so there should be no trouble understanding what connects to what.

• If you want to connect any other coordinates to the system on the gimbal camera composite node, please put the
  Coordinates in this order:
  x = channel 1, z = channel 2, y = channel 3.
  This is because of the Gimbal Camera using those channels so I had to use them too.

• 22 March 2021: Version 2 is out! I added a Lua interface to display basic target information. There's
  three fonts you can choose from; Default, Dark mode and Old. It's pretty simple and optional but I thought it might
  add a little more overview to the system. A huge thanks to Lassi who helped me by
  implementing a better guidance system. The torpedo might be a bit unstable in terminal phase but will still hit its
  target with an +/-0.5m accuracy. Hope you guys like it!
  
• 24 March 2021: -Fix: Torpedo would return to launch station when launched without input data.

This is a Work-In-Progress. It does work completely fine but I do want to add more features / improve on them.
Possible additions/updates might be:

• Even though the radio frequency is randomly generated, with radio scanners it is fairly easy to jam the
  communication frequency. That's why I am considering pointing a gps guided laser on the target and making the
  torpedo laser guided. That does not come without downsides though. The torpedo would have a limited field of
  view compared to the basically 360° FOV of the gps guidance. Also, countermeasures would not be impossible,
  e.g. a laser beacon buoy could confuse the torpedo and guide it somewhere else.
  
• A lua interface for launching and tracking torpedoes and targets Done
  
• An included Sonar Tracking System

Make sure your Sonar is tracking something, if not you should use the Gimbal Camera instead. The Sonar does glitch in-game sometimes and stops tracking vehicles. Also check if everything is connected right. If that does not work, leave a comment and I'll try to help.

Can be used and modified without credit

A big thanks to Exob, Kubson, Dark_Shadow65 and amccoy2014, who helped me find solutions for problems with radio communication and other problems. Especially Lassi, who gave me a function for PN interception which works great.

You'll find all controllers on my workshop if you wan't build your own guided Torpedo.

Have fun!
