Questions About UAV S20 Aerial Mapping Equipment

What is the recommended flight altitude?

Between 25 and 50 meters ( minimum 10 m – maximum 100 m)

What is the maximum flight duration?

Up to 15 minutes with full batteries. It is recommended to land the UAV when battery level is at 25%.

Can you fly STORMBEE in both autonomous and piloted mode?

YES, both are possible. We recommend to fly autonomously to achieve highest scan data quality and accuracy.

How fast can STORMBEE fly?

Depends on the weather conditions. Stormbee can fly up to 15 meters/second (50km/h, 30mph). The recommend flight speed during scanning is between 3meters/second (10km/h, 6mph) and 8 meters/second (30km/h, 18mph) to achieve the best results.

What weather conditions can STORMBEE handle?

Fly only during dry (no precipitation) weather conditions. Max wind speed : 30 km/h. Do not fly during icing conditions ( atmospheric temperatures below 0°C ). Note that the most FARO Focus scanners currently shut down below 5°C. Only daytime operations are allowed.

What is the accuracy?

The accuracy of the laser scan data depends on the quality of the positioning measurement system on-board the UAV, not the type of FARO scanner. The FARO scanner itself has a 1 mm accuracy (standing still on the ground). Combined with the APX20 Applanix positioning module used by STORMBEE, overall accuracies around 1-2cm can be obtained during flight.

Are all FARO scanner types compatibel with STORMBEE?

NO, just the scanners with the “automation mode”. The client should check the laser scanner’s article number which should end with a letter A. The FARO focus X and S series have this option, the M series has not.

What is the field of view around the scanner under the UAV?

The scanner has an unobstructed field of view of 300 ° (in the vertical plane).

What is the total weight of the STORMBEE solution?

Depending on the type of scanner and batteries the weight will be between 20 and 22 kg (55lbs).

Do you need pilot license?

This depends on the regulations of each country you fly in. Pilots of STORMBEE are required to have received UAV (multicopter/helicopter) training prior to following the STORMBEE training, preferably being a licensed UAV pilot. Additionally, STORMBEE provides a mandatory 2-3 days training to learn to fly specifically the STORMBEE UAV.

Is STORMBEE compatibel with other scanners, camera?

NO, STORMBEE is only build for LIDAR use and is only compatible with FARO Focus scanners. It is not possible to mount any other kind of camera or payload.

Can the client use his own FARO scanner?

YES, client only needs to switch the setting in the scanner to the “helical mode”, a simple procedure described in the STORMBEE user manual. The client’s scanner is attached to the STORMBEE platform using 4 screws. This takes only 2 in minutes.

Does the client need RTK or ground control points?

NO, only if the client wants to increase the accuracy of the laser scan data further. The standard accuracy can also be improved by using additional post-processing software packages, RTK, ground control points or a dedicated base station depending on the mission type and client preferences.

Can STORMBEE fly indoors?

NO, STORMBEE requires a GPS connection for its flight control and concrete reinforced walls and roofs block the GPS signal.

What point density can you collect per square meter?

The point density is usually around 1000 points per m² depending on the scanner setting (488,000 measurements per second), flight altitude (20m from scanning object) and speed (14 kilometres per hour , 8 miles per hour). Maximum scan rate (976,000 measurements per second) , slow flight speed (7 kilometres per hour, 4 miles per hour) and 20m flight altitude results in a point density if almost 4000 points per m². The ranging noise is approximately 1 mm at 25 m distance.
