Our Services


We provide turnkey solutions for clients comprising hardware, personnel and product delivery. Our current UAV airframe is the impressive Prion Mk3 which is ready to be deployed for your observation (streamed video surveillance), surveying (aeromagnetic surveys) or payload (humanitarian aid) delivery requirement. With a tricycle undercarriage or skid landing gear the Prion can launch from a grass airstrip or otherwise via a compressed gas launcher where no airstrip is available. Equipment, personnel and local staff training are all offered in order that you can control the use of the Prion whilst we are able to ensure the system is configured correctly for your deployment requirements, and the safety of people, property and the Prion is maintained at all times.

Safety and adherence to local civil aviation authority terms of flight operations form the basis of the early planning for any new engagement. We next aim to understand any access and take off / landing limitations of the terrain at the Base Station location. The technical demands of the Prion can then be considered in order to fulfil the project requirements, whilst building in sufficient redundancy into our flight planning to allow for the safe recovery form any mission in the unlikely event of a systems or component failure.

Typical field crews will comprise a minimum of two persons. The training of client personnel is achieved through a combination of formal classroom training, structured in the field practicals and on-the-job training working in a support capacity to an established field team. If a long term service provision for the use of the Prion is required, we aim to facilitate establishing and the continued support of such a turn key arrangement.

Prion aircraft are manufactured and owned exclusively by UAVE Limited. These are subsequently leased to each client project or aircraft are sold to the client outright. Leases include a regular equipment Servicing contract extending to include cover at any location.
