Augmented UTM (AUTM) example:
The results of such elevation angle and range distortions may not be so apparent when all simulations involved use AUTM. However, in a federation involving GP SRFs, the distortions may become evident. Use of AUTM increases visibility, causes interactions to prosecute too fast, leads to an uneven playing field, and is not recommended for use in joint simulations.
Several distortions are introduced, especially at the higher latitudes
