DVI2AM® Drone for VOR and ILS/Infrastructure Advanced Maintenance

Mission:

Inspection is a crucial factor for the evaluation of facilities performances asrequired by ICAO. Traditional procedures rely on ground check using special and expensive vehicles or instruments, together with
periodical flight checks. Based on these premises, Techno Sky, as part of ENAV Group, has developed its own UAS solutions for near-ground ight inspections of NAVAIDS and airport infrastructures.

Operational Scenario:

TheDVI 2AM® productis a high-performance drone that can be equipped with instruments such as compact VHF/UHF receiver/analyzer, spectrum analyzer, high - resolution camera or infraded camera and dedicated payload for FOD detection, assessment of runway/taxyway pavement status and bird control.

• Better cost efectiveness compared to traditional ground check vehicles and equipment
• High flexibility of operations achieved by handling customized payloads
• High precision GNSS+RTK positioning
• Drone solution forILS ground check approved by Italian CAA as an alternative forGround Check Vehicle
• Performing BVLOS operations (if approved by local regulator) enabling cost reduction also via implementation of centralized control centers

 
Regulations and certifications:
Reg.EU 2019/947
ICAO Annex10 Vol I
ICAO Doc 8071 Vol I
• FTS compliant to EASA MoC Light-UAS.2511
• Class Mark C3 (Reg. EU 945/2019)
• Reg. EU 139/2014
• Parachute compliant to EASA MoC 2512

Main capabilities:
Our drone solution can inspect and/or perform
measurements on the following types of facilities:
• ILS (GP and LOC)
• Marker
• VOR
• DME
• PAPI
• Communication channels (VHF/UHF)
• GBAS
• Runway and taxiway pavement integrity status
• Elevated infrastructures status (e.g. RADAR RADOME)
• Airport lightning visual aid
• FOD detection (Foreign Object Debris)
• Airport perimeter surveillance

Main Measurement profiles for NAIVIDS (ILS and VOR):

• ILS Localizer Course Alignment: dynamic analysis of Localizer, carried out across the runway axis at constant speed and altitude, allows to analyze the magnitude of interest such as Dierence in Depth of Modulation (DDM), Sum of Modulation Depths (SDM), 90/150 Hz Modulations (MOD 90/150)
• ILS Localizer Displacement Sensitivity: dynamic analysis performed crossing the runway heading towards the Localizer and passing over the threshold. This process measures the ratio of Dierence in Depth of Modulation (DDM) to lateral displacement, ensuring precise alignment and sensitivity
• ILS Localizer Off-Course Clearance:
dynamic evaluation of signal integrity and coverage beyond the course sector, performing an arc of +/- 35° at a radius of 150 meters from the Localizer center. This process ensures that the Localizer provides accurate guidance and maintains signal clarity even when the aircraft is of-course
• ILS Glide Path: static and dynamic analysis of GP, carried out raising the drone to a pretederminated altitude on a fixed point e.g.  runway threshold), allows analyzing DDM and its temporal stability at several altitudes of the runway perpendicular
• VOR stability: static analysis of VOR antenna carried out acquiring data in specific positions on the reference radial or other default, allows analyzing the temporal stability of the magnitudes of interest.

Payloads:

Leveraging on high flexibility, Techno Sky UAS can be equipped with different payloads such as:
• electro-optical camera
• infrared camera
• multispectral camera
• VHF/UHF analyzer
• LIDAR
• Speaker

Ground Control Station:

Techno Sky UAS is equipped with a customized HMI that allows:
• planning of ight missions
• command & control
• real time data display
The HMI is battery powered and can be easily carried to site and mounted on a standard tripod. It includes all devices that allow a reliable and stable datalink with the drone during ight. It can be also equipped with an external RTK base station to ensure high-precision GNSS positioning.
