What We Do

We specialize in building inspections, for which we use drones equipped with visual and thermal infrared cameras. Our strategic partnership with Inspekt AI, a US-based international firm, involves providing drone imagery to facilitate image analysis and modeling using their proprietary AI technology. This collaboration aims to help building owners and managers save money by identifying defects that could become more expensive to repair over time and pinpointing areas where buildings are experiencing costly energy leaks. Our approach is not only quicker but also more cost-effective compared to traditional inspection methods. Read our article about the importance of inspections in reducing energy wastage and greenhouse gas emissions.

Other than inspections, we are happy to work projects for private individuals as well as with companies that have sites for which they need aerial data (e.g. photos, videos, maps, stockpiles measurements). The uses of such data include monitoring changes in your work environment or in construction project progress, acquiring whole-site or site-elements images for public relations and advertising purposes, monitoring the status of rooftop conditions or of farm crops, property sales, website imagery, support for insurance claims and many more. Essentially, if you need to see your site (or home) from above, we can offer you quick, reliable service at an affordable price. Our operations are fully insured for liability, in accordance with Swiss law.

We can do cut and fill measurements that allow you to confirm that you got the volumes you paid for.

Parhelion also publishes a variety of drone logbooks for professional and hobbyist operators. We offer a selection of UAV Pilot Logbooks and are the first to publish dedicated UAV Aircraft Logbooks in which you can record and keep track of your machine’s maintenance, current condition and use history.

Who we Are

Parhelion Aerospace brings over 35 years of professional aviation industry experience to the relatively new world of drones operations. Our work with UAVs is therefore informed by our experience working with standard aircraft. The same rigor that characterizes the world of professional aviation in general is applied here; as a consequence our aircraft are properly maintained, our pilot is well trained, our flights are thoroughly planned, airspace use, insurance and legal considerations are meticulously observed, and all flights are conducted safely. Our mission is to set a standard of operational professionalism that will lead the drone services industry here in Switzerland. Parhelion Aerospace is a Swiss Bundesamt für Zivilluftfahrt (BAZL)-registered drone operator company. All of our operations are fully insured for liability, in accordance with Swiss law.

Our pilot is a BAZL – registered drone pilot who is fully trained and certificated for the work that we do: he has the A1/A3+A2 Swiss Remote Pilot Certificates, the USA (FAA) Part 107 Remote Pilot Certificate and the ISO 18436-7 Cat 1 Infrared Thermography course certificate. Our pilot is skilled not only in the use of our own equipment but has considerable experience flying the Swiss-made Wingtra UAV (a flying-wing design) and the Matrice 300 RTK, doing professional piloting work for the Zurich-based firm Nomoko, a digital-twin creator. He has the EASA and FAA Airline Transport Pilot licenses and many years of experience flying jet aircraft around the world, so he is very familiar with safe and professional procedures for the use of flying machines.

We are a member of the Swiss Property Owners Association.

The Equipment We Use

For inspections we fly the Mavic 3T (thermal) drone. This professional-grade aircraft is perfect for the buildings inspections mission: it is small, quiet and highly maneuverable. It possesses three cameras, one of which is a very capable radiometric thermal imager. It is able to take coordinated visual and thermal images of the same place at the same time. The Mavic 3T, moreover, has the latest in safety and obstacle avoidance capabilities.

We also fly the Mavic 2 Pro and the Inspire 2 professional-grade drones, for photography, mapping and videography purposes. The Inspire is equipped with the X5S camera and an array of high-quality Olympus and DJI lenses. The Mavic is equipped with a Hasselblad camera and is capable of shooting 20 megapixel photos and H.264, 4k Ultra-HD videos.

Color photographs can be made up to poster-size at 20.8 megapixels. Video data are most commonly delivered as H.264, 4k Ultra-HD, but we can deliver Ultra-HD data up to 5.2K. Additionally, for those who require more post-processing latitude we can deliver your data in D-Log ProRes 422HQ. Samples of our work are presented on this page; in fact, all of the images and video on all of the pages in this website are our own shots (except where stated).

Where we Are

Parhelion Aerospace is based in the Seeland area of Switzerland, near the city of Biel and at the foot of the Jura mountains. We are therefore centrally located and can support projects throughout Switzerland and the nearby regions of France and Germany. For the right sort of project, however, we will travel the world!

Our logbooks are sold online and are therefore available anywhere.
