I can assure you that VLT is capable of detecting the radiation at almost any wavelenght. VLT (Very Large Telescope) is an Observatory that contains five telescopes, each one with at least two instruments, and every instrument is set to different wavelengths. See more at www.paranal.cl.
I think nobody has noticed that a WAAS enabled GPS will not achieve the precision given by WAAS, but only the standard GPS precision (somewhere between 20 - 5 mts.). In other words, a WAAS enabled GPS WILL work, but it will not use its WAAS feature at all. If the guy is going to buy a new GPS, don't make him waste extra on a feature he won't use.
