A fourth speaker has joined the panel of the free April 20 webinar, “From Flying Drones to Doing Business,” addressing UAVs in business applications. Francois Gervaix, product manager of surveying for senseFly, will address the business benefits of high precision GNSS, covering: high precision in photogrammetry drones, survey-grade accuracy, workflow flexibility and time/cost savings.

Webinar attendees will have the opportunity to ask direct questions of the speakers, both upon registration and during the live event. Register for free at

Gervaix joins a panel consisting of Gustavo Lopez, product manager GNSS solutions for UAV applications for Septentrio; Jan Leyssens, 
managing director of sales and business development for Airobot; and Zak Kassas, assistant professor in the Department of Electrical and Computer Engineering at the University of California, Riverside.

Other subtopics to be covered include the integration of various surveying and mapping sensors aboard a UAV platform; meeting safety demands for UAVs by providing intelligent safety components, specifically designed for drones, and in facilitating end-users’ success in completing their missions; and exploiting long-term evolution cellular signals for accurate and resilient autonomous vehicle navigation in the absence of clear GNSS signals.

Gervaix is a qualified geomatics engineer who has worked for Leica Geosystems and as a professor at the Technical University for Applied Sciences Western Switzerland. In 2010, he launched project R-Pod, Photogrammetry on Demand, before founding Easy2map, a drone-based photogrammetry service provider. He joined senseFly in February 2016. He is also president of the Swiss Society of Photogrammetry and Remote Sensing.
