I'm a software developer, don't know much about the hardware specifications and don't know where to start. (Even not sure is that the right stackexchange I should ask this question.)

So, I want to know about (1) the cost and (2) document, link, etc. for the following specifications:

I want to make a project which I will put a chip (?) to a user and track that users 3D location with at least 10 cm accuracy, 10 times a sec, in a particular approximately 25x40 meters place and use that 3D location in my C, C++, Python, Java application. I read something about triangulation, and it makes sense. However that's all I know. I don't know any device that I can buy to do such...

Can you send me something to read?
