GPS signal into simulink via arduino

Hi to all! I'm new here..I'm Valerio and i'm pleased to be part of this forum.

My problem is: I have an autopilot built in Simulink and loaded on my arduino mega board. I have several sensors attached to the board and there is also a GPS rx/tx.

Now i would achieve this goal: I would transfer the NMEA data arriving from the GPS antenna into Simulink with a blockset (that I cannot find until now) having the three coordinates as output.

Is it possible in your opinion? If yes, can you describe the right procedure in details?

I thank everyone for the help.

I am not aware of any blockset directly produced by MathWorks that fulfills this requirement. However, there may be 3rd party blocks that I am not aware of. Also, what is the exact model of the sensor you are doing? You might want to do a web search to see if you can find a Simulink-based block driver for it. If not, you can follow the technique decsribed in Integrating Device Drivers to integrate existing C/C++ drivers as a Simulink block.

Thank you for the kind answer; So your opinion is that i should create a new block through S-function where i describe what are inputs, outputs, and the transformation in the middle. Is this correct? Thak you for helping me.

If the transformation is possible with blocks from the Simulink library, then you need S-function driver blocks for the inputs and outputs only.

Hello,

There is an application example to Read Serial Data from a GPS Shield Using Arduino Hardware for Simulink available from R2018a: https://www.mathworks.com/help/supportpkg/arduino/examples/read-serial-data-from-a-gps-shield-using-arduino-hardware.html

This is just in case anyone is looking for a similar solution.
