Got GPS? Thank Hedy Lamarr
I know what you’re thinking, and you’re right. Hedy Lamarr, the gorgeous and glamorous Hollywood star of the ‘30s and ‘40s, had nothing to do with the invention of GPS. She did, however, invent a technology that underpins almost all modern communications. Lamarr and avant-garde composer George Antheil invented and patented a technology that Bluetooth,...
Drones over Venus
While attending the AUVSI XPONENTIAL conference last May, I spoke with the team at Black Swift Technologies, a Boulder, Colorado-based UAS engineering firm specializing in scientific platforms, and I asked them to keep me updated with their progress. I recently received the news that it has been awarded a NASA contract to develop a UAS...
Find Your Home – on Pangaea
First, a bit of “geosplaining.” When we started this newsletter we looked for a name that had a “geo” feel without having geo in the name. For those who don’t follow geology, Pangaea was the most recent supercontinent which was formed roughly 200 to 250 million years ago, according to the plate tectonics theory. Flash...
Will Drones Replace Fireworks?
Here’s a slice of life from the western edge of the Eastern Plains of Colorado. As I write this, the Fourth of July is tomorrow, and I’m shopping for our holiday “staycation.” BBQ pulled pork, buns, baked beans, corn on the cob, and “tater salad.” Check. Should I pick up some fireworks? The informational sign...
NASA’s Awesome Long-endurance VTOL UAS
The wizards at NASA’s Langley Research Center took a look at the current state of UAS and found two big problems: The flight time and range of electric multicopters is too short, and many fixed-wing UAS require extensive ground support for launch and recovery. With these challenges in mind, the team came up with two...
Low-cost Tech for Aerial Archeology, Part Two
To round up this short series on low-cost approaches to aerial archeology surveying, we’ll look at an even lower-cost sensor technology that can be used in certain types of archeological projects. In the first part of this series we talked about how new, affordable multispectral sensors are being used with (relatively) inexpensive UAS to find...
