The camera has a 30 mm lens installed. Optionally a 19 mm lens can be ordered.

You cannot use the same camera because it has to be permanently modified by a specialist. In case you need such a camera it has to be ordered separately.

The ground coverage from 120 AGL is 94 m x 62.4 m.

The photos are downloaded directly from the SD Card connected into the computer.

Usually you would need to replace the system's propeller blades. During its lifetime the fuselage or wings might also need repair or replacement if they are used in a harsh environment.

The UAV can be equipped with color RGB, NIR, multi-spectral, hyper-spectral cameras or gas detection sensor.

The maximum payload weight for BRAMOR ppX is 500g.


The cruise speed of the UAV is 58 km/h.

The strongest wind it can fly can reach up to 17 m/s.

Total weight of the system (incl. catapult launcher and GCS) is 30 kg.

The aircraft can be equipped with a locating beacon upon your request.

Flights can be executed up to 5000 m above sea level.

The aircraft can be optionally equipped with a locator beacon.

Replacements usually include propeller blades and batteries. During it's lifetime the fuselage or wings have to be replaced if the UAV has been used in a harsh environment.

Standard flight time at cruise speed for Bramor ppx is up to 3,5hours, depending on the wind conditions and flight altitude.


The UAV lands with the parachute.

Users usually land inside a radius of 20 m from the GCS. With more experience, they get even more accurate.

The take-off is achieved with the catapult launcher (elastic or pneumatic).


With the GeoPilot flight planning software the user can create flight plans consisting of arbitrary waypoints or automatically create areas of arbitrary shapes or linear shapes like roads, power-lines, rivers, etc.
