How to make a GPS positioning device using a microcontroller? Can I use my mobile phone to check the GPS location? Please give me a tutorial.

This seems a bit difficult, so for convenience, buy a GPS module, buy a GSM module, get a phone card and insert it into the GSM module, and use a microcontroller to receive GPS information, usually RS-232 Interface, the GSM module is responsible for communication, and is also connected to the microcontroller, and then sent to your mobile phone in the form of text messages through China Telecom or China Unicom network. OK, if you want to see the specific location, you need to develop a message on your mobile phone. This is the positioning software for maps and GPS information.
