GPS wouldn't work. Even though the government disabled Selective
Availability last year, commercial GPS still doesn't achieve an accuracy
better than several meters. I would imagine that for GPS to be suitable
in such a competition, it would require an accuracy of no more than a
few inches, and would require that all of the platforms were equipped
with *exactly* identical GPS modules manufactured with very rigorous
tolerances. Also, getting a lock inside any building is difficult and
unreliable at best, and it appears that these types of competitions are
generally held in large steel buildings, an environment totally
unsuitable for receiving a GPS lock.
What about some sort of standardized IR beacon pulse on an
omnidirectional emitter, and equipping the platforms with a servo-driven
rotating unidirectional detector? Since all of these competitions seem
to be one vs. one, have standard emitter designs with two pulse
frequency settings. Then, one competitor could set their locator system
to Mode 1, and the other to Mode 2, preventing a platform's emitter from
interfering with its own detector.
