Return to main article: "True3D HUD Wins Global SatNav Competition"
Many technologies are created before their best applications are even thought about. This leads to a business phenomenon known as “technology push” in contrast to “consumer pull.” The True3D Volumetric HUD technology did not share this path.

No sooner had GPS positioning helped validate key aspects of Einstein’s general theory of relativity in the Gravity Probe-B program than GPS timing has been cited as helping bring his special theory of relativity into doubt.
At issue is the so-called OPERA (Oscillation Project with Emulsion-tRacking Apparatus) experiment, inaugurated in 2006 with the main goal of studying the rare transformation (oscillation) of muon neutrinos into tau neutrinos.
