Had the residents of Landshut, a 13th-century city in Lower Bavaria, chanced to look up at the right time over the last few weeks, they might have glimpsed a bright yellow shape looking back at them.  Calin Gologan’s latest Elektra One Solar carries a suite of cameras that can transmit 2D movies in 4K resolution to a ground station up to 40 kilometers (25 miles) away.  Through sophisticated software, the images can be translated into 3D maps with a resolution of five centimeters (just under two inches), the primary mission of the flights. Partner ViaLight, a 2009 spin-off of the DLR (the German Aerospace Center), provided the hardware and software that allows up to 100 Gbps (gigabits per second) data …
