NAVAID Calibration Drone by Cursir helped speed up flight check of landing system of the Ulyanovsk airport


The aerodrome at the Ulyanovsk-Vostochny airport has a difficult terrain

Last year, by order of the Federal Air Transport Agency of Russia, a working group was created to implement UAVs to calibrate, check and configure navigation aids at Russian airports. As part of the activities of this working group, Cursir implemented NAVAID Calibration Drone at the Ulyanovsk-Vostochny airport.

NAVAID Calibration Drone is a mobile radio measuring complex developed by Cursir (subsidiary company, R&D department of RTS Union). It was used to pre-configure the radio equipment system at the Ulyanovsk airport. The use of the drone made it possible to reduce the number of flights of a specialised aircraft (a flying laboratory), speed up NAVAID commissioning and cut maintenance costs.

NPO RTS, the head structure of RTS Union, is carrying out a contract to install an ILS 734 (instrument landing system) and an RDF 734 (radio direction finder) at the Ulyanovsk-Vostochny International Airport. At the commissioning stage, NPO RTS engaged Cursir to carry out system checks using NAVAID Calibration Drone. In June 2021, the Drone performed diagnostic flights, during which it obtained data for preliminary adjustment of ground equipment.

Alexander Tyurkin (Lead commissioning engineer, NPO RTS) said, “The aerodrome of the Ulyanovsk-Vostochny airport has a difficult terrain, which complicates the initial configuration of the equipment. The use of a NAVAID Calibration Drone made it possible to set up the system in a short time and prepare for control flights performed by a special flight inspection aircraft.”

Vitaly Munirov (CEO, Cursir) noted that the use of NAVAID Calibration Drone radically changes the nature of commissioning, accelerates and reduces the cost of further flight inspections.

“Thanks to the use of a UAS platform, it is possible to perform preliminary configuration of the equipment without the involvement of a flight inspection aircraft. The cost of operating a NAVAID Calibration Drone is noticeably lower than that of a specialised aircraft, and the extensive functionality makes it possible to effectively solve a significant part of the tasks that arise during flight check of radio aids,” he said.


The NAVAID Calibration Drone used by Cursir was designed for in-flight measurements of radio technical flight equipment. The Drone consists of a UAS platform, receiver and software. Due to its low weight and compact size, the receiver is placed onboard a UAV. The complex is highly functional: it can measure the parameters of such radio and navigation equipment as ILS, VOR/DVOR, RDF and light equipment. 

Compared to traditional measuring systems carried by flight inspection aircraft, the NAVAID Calibration Drone can significantly reduce the cost of performing flight checks by lowering the cost of performing many hour flights in the airfield area, flights between airports, also eliminating the cost of wages for flight crews.

Cursir was founded in Russia in 2015 to carry out scientific and practical research in landing and navigation systems and systems for their diagnostics and control.
