Hello everyone
currently i am researching to design an NMEA to synchro signal converter. but I don't know how this conversion principle works. I also don't understand how to control a selsyn with a microcontroller.
Can anyone help me or provide me with documentation on this issue. I would like to thank everyone very much.

That's a complex digital to analog converter project. The signal decoding and 60/400Hz three-phase + driver coil outputs could be handled with a 32-bit processor board like this if you need high precision positioning and signal generation but the programming is not trivial but you can sorta fake the drive signals using a Arduino uno or something like that. There just is not much simple DIY information on building things like this.

The board has two RS232 and one RS422/485 ports for communications.
