A solar flare 10 times stronger than anything researchers had previously observed or predicted surprised scientists last December, not only because of its size and strength, but because of the effect it had on GPS receivers and other communications systems.

Mercury Computer Systems introduced two new class II-qualified electronic flight bag (EFB) systems targeting operators of larger aircraft. Mercury’s original VistaNav EFB class-I CIS-1000 is a tablet PC offering a 2-D or 3-D synthetic view of the outside world, including highway-in-the-sky approaches. The tablet receives wireless signals from a separate inertial navigation unit housing a WAAS GPS receiver and solid-state gyros.
