A target that is usable in a position determination system such as, for example, a wheel alignment system, is structurally stable over wide temperature ranges, protected from humidity and chemical contamination, and not subject to breakage. A layered target structure includes a substrate board, a retro-reflective layer formed on the substrate board, a transparent sheet overlaying the retro-reflective layer, and an opaque patterned layer between the a retro-reflective layer and the transparent sheet. The layered target structure may be secured a support assembly.
