You don't need advanced math for navigating, but sin and cos for
calculating coordinates in an X/Y coordinate system. This you need
independently from your steering system. Brickos has no math lib, but
there where some posts on this list some times ago with trigonometric
math functions.
Lejos has sin and cos and even classes for X/Y navigation with
rotationsensors, but I think, it would be interesting to try navigation with
C/C++/Brickos, just because the rotation navigator class from lejos has
bugs and the lejos project seems to be dead, so that no improvements can
be expected.
Here is a tutorial for navigation with lejos:
