Laser-powered UAS

This entry is part 25 of 25 in the series PangaeaAs noted in our latest issue about tethered drones, the ability to power UAS from the ground exponentially increases flight times and allows the use of heavier sensor payloads. Tethering accomplishes this at the cost of range, however: generally 200-400’ with commercially available tethering systems....

The Power of Tethered Drones

This entry is part 1 of 25 in the series PangaeaBefore the FAA’s Rule 107 allowing UAS use for commercial work, we waited patiently (and often impatiently) for the day when UAS would be “unleashed.” Ironically, now a new class of UAS gets its power from actually being on a leash. Tethered drones use a...

Color coding in this image of Mars represents differences in elevation, measured by NASA's Mars Global Surveyor. While surface liquid water is rare and ephermal on modern Mars.

Straight on to Mars (and Beyond)

This entry is part 24 of 25 in the series PangaeaIn the last issue we raised the question of whether mankind should go back to the Moon as a way to fuel future space exploration. While that article states the many salient reasons to take this path, many people feel we should aim higher and...

Aerial Data Collection: Little Drone Takes on Big Airport

This entry is part 6 of 7 in the series May 2017In a first-of-its-kind project, a UAS is tasked to collect aerial data of an international airport. By Jeff Salmon Normally when you add the words “drone” and “airport” to a sentence, it classifies as cringe-inducing. Just the opposite is true with this ground-breaking UAS...

UAS: From FUD to FOMO

This entry is part 3 of 7 in the series May 2017By Jeff Salmon Welcome to our semi-annual UAS-focused issue. Looking back over the last six years of UAS development, I am struck by how far the technology has progressed. Right before our eyes a new industry has developed, one that promises to bring far-reaching...

Should we settle on the Moon before Mars?

Back to the Moon? Or—Straight on to Mars?

This entry is part 2 of 25 in the series PangaeaEditor’s note: at xyHt and Pangaea we’ve been adding “geo-space-al” content into our geospatial mix, and readers have been responding positively. Surveying on Mars is a great example. When you think about it, geospatial technology and space are inextricably intertwined; from GNSS to satellite-based remote...
