21 June/July 2016 unmanned systems inside Professional systems are also known for their reliability, which is key during mapping, said Francois Gervaix, product manager for surveying at senseFly. Systems should repeatedly provide the same quality information, no matter where they're f lown or what the application. Thomas Haun, vice president of strategy for PrecisionHawk, agreed. The UAS and the sensor need to repeatedly and ac- curately capture the data, he said, so it's possible to repeat the f light and look at trends in the data over time. That's exactly what Alex Pearson, who owns AG UAV, was looking for when he decided it was time to add a multirotor drone to his f leet. He always had been wary of multirotor air- craft—especially because he tends to f ly over active construc- tion and quarry sites where people are working. With an un- manned fixed-wing platform, even if something goes wrong, it's fairly easy to control and recover the aircraft. He doesn't have that confidence in a multirotor, or at least he didn't. After researching the options, Pearson decided to go with the md4-1000 from microdrones. He knew it was a reliable system that wouldn't falter even in a gust of wind, and would safely col- lect data of the area being surveyed. "The craftsmanship and quality of the product is extremely high. I'm very happy to show it off to any of my clients who want to take a closer look," said Pearson, who also noted the drone's endurance. "And this is coming from someone very wary of multirotor aircraft. They've really won me over in terms of how much I trust it, how reliable it is and how easy it is to use." Effciency Benjamin Benharrosh, co-founder and sales and marketing di- rector of Delair-Tech, said advanced systems reduce the time spent in the field. Delair-Tech manufactures the DT18 and the DT26X and was one of the first companies authorized to f ly UAS beyond visual line of sight. Operators can check the qual- ity of the data and make necessary adjustments to the pro- fessional grade camera's parameters during f light—a feature starter systems don't have. "If you go with a system that's too basic the quality of the data will not be good enough," Benharrosh said, noting the need for quality sensors and accurate IMUs (inertial measurement units). "Maybe three or four years ago people tended to use the cheaper systems because they wanted to discover the technology. Now they realize the quality of the data and the accuracy were not good enough. So now people already using UAS technology are switching from basic to more professional tools." A miniature IMU Weight: 0,12 lbs (55g) Volume: 2,0 cu. in. (35cm 3 ) • When size, performance and robustness matter Available now – contact us to discuss your application Certain missions demand unsurpassed precision, stability and reliability. Having perfect control and fully understanding the smallest detail is what it takes to be a world leader. With this in mind, we developed the Inertial Measurement Unit STIM300, a small, utra-high performance, non-GPS aided IMU: • ITAR free • Small size, low weight and low cost • Insensitive to magnetic fi elds • Low gyro bias instability (0.5°/h) • Low gyro noise (0.15°/√h) • Excellent accelerometer bias instability (0.05mg) • 3 inclinometers for accurate leveling STIM300 is the smallest and highest performing, commercially available IMU in its category, worldwide! … TO BE EVEN BETTER!
