Zala Aero Unveils Zala 421-16 UAS Upgrade

Zala Aero has launched the latest version of its Zala 421-16 unmanned aerial vehicle (UAV) with a focus on civil sector aerial photography customers. The newest version of the system includes a dual frequency GPS/Glonass receiver TRE-G3T with frequencies L1 and L2 supporting RTK increasing the accuracy of the aerial photography coordinates to centimetres.

The company is aiming the upgraded 421-16, originally launched in 2009, at the energy and land management sector as a ‘cost-effective solution’ for large scale aerial photography, with coverage of over 1000 km in a single flight.


The system has also been equipped with two high-resolution professional cameras that make it possible to obtain 3D images with accurate coordinates embedded, to increase the data output available. 


The 421-16 interchangeable power plants have not been modified, the company said, as the two-stroke and four-stroke engines offer a selection to customers depending on different mission characteristics.
