It is a mathematical system which helps with space curves; it starts with the idea that the tangent to a curve can be found by taking the derivative of the curve's functional definition wrt the distance along the curve.

Then two more orthogonal vectors are created, providing a co-moving orthogonal reference system.

This is usually first encountered in a vector calculus course, though it is useful in many areas of engineering.
