![]() ![]() The ATLAS drone allows to improve the ILS inspection operations by dramatically reducing the manned aircraft flight check frequency and thus decreasing the overall operational cost for airport operators. The ILS check drone is currently used by skyguide in Geneva (GVA – LSGG) and Zurich (ZRH – LSZH) airports. The development of the ILS-check UAV solution involving an OnyxStar® ATLAS drone, started in 2015 and is operational since January 2018. OnyxStar® ATLAS improves airport management and aircraft safety Thanks to its lifting power, efficiency and reliability, the CNS drone performs inspections in the far field. Elevation profiles and mini approaches are conducted by the ILS inspection UAV in order to analyze the ILS signal (course alignment, slope angle, alarms, displacement sensitivity, etc.) and complete the ground and manned flight measurements. This is where the solution developed in a partnership involving AltiGator and skyguide intervenes. The ground ILS (Instrument Landing System) calibration operations are indeed restrained to the runway threshold, since they are performed using masts that generally don’t go higher than around 25 meters, from the ground. It requires preparation together with ground measurements in order to optimize the manned flight intervention.īoth of the above operations have their limitations: the manned aircraft is costly, noisy and environment unfriendly while the ground one is limited in terms of reachable distance and height. The regular ILS (Instrument Landing System) calibration control is made in flight, using a manned aircraft. These companies are always looking to improve these processes. In order to maintain the ICAO ILS certification, dynamic measurements need to be performed by the airport operators, their subcontracted flight inspection organizations or government agencies. ILS is an essential navigation aid to help pilots land their aircraft in low visibility conditions during IFR flights (Instrument Flight Rules). OnyxStar® ATLAS is a CNS drone operating ILS checks since January 2018 To achieve this, a combination of ground and air inspections are necessary, like the localizer measurements for ILS CAT III ( Instrument Landing System). This means that these systems must be tuned to radiate the correct signals in the airspace, at any time. Indeed, Air Traffic Management (ATM) companies strongly rely on advanced, unfailing and efficient navigation aid equipment in order to accomplish their mission in the best conditions.Īmong the numerous requirements from ICAO ( International Civil Aviation Organization), Flight navigation systems must be regularly calibrated, inspected and maintained to ensure that all essential navigation aids for pilots are always working properly. These systems enable Air navigation service providers to ensure that aircraft can reach their destination in due time safely, despite the permanent density increase. ![]() AltiGator and skyguide use drones for the calibration and maintenance of automatic airport landing systems OnyxStar® ATLAS is world’s first drone to perform ILS check flightsįlight navigation systems are essential in a world where the global air traffic growths continuously.
