The use of a Demand-Controlled Night Marking of Wind Turbines (BNK) is requested by law in Germany from 01.07.2021. This can be achieved through a system that makes use of transponder signals of surrounding aircraft.
In co-operation with f.u.n.k.e. AVIONICS Deutsche Windtechnik has developed a global and independent system for this purpose.
The transponder receiver unit x-BNK, developed by f.u.n.k.e. AVIONICS, represents the core component of the overall system. This device receives signals from approaching air vehicles, performs a respective verification and activates the danger fire if needed.
At the end of an intensive test campaign over several months, including as well overflight testing via a drone around a wind turbine, the system finally received certification on the 17th of September 2020 through airsight GmbH, the first official testing authority named by the Federal Ministry of Transport and Digital Infrastructure.
This certification proves once more the profound know-how and long lasting experience of f.u.n.k.e. AVIONICS in the field of Mode S transponder technology. The system has now entered production stage and and is ready for widespread installation in the years to come. The system is sold exclusively via our partner Deutsche Windtechnik (www.deutsche-windtechnik.com/bedarfsgesteuerte-nachtkennzeichnung-bnk).
In early 2018 f.u.n.k.e. AVIONICS GmbH signed a contract with Thales Alenia Space France (TAS-F) to supply subsystems for the Uplink Station (KUS) in the frame of the South Korean Augmentation Satellite System (KASS) which is currently realised by Thales Alenia Space.
Development of the subsystems was now concluded and respective units were delivered to TAS-F.
The KUS SGS Integrity Box (IB) is part of the KASS Uplink Station. The main function of the IB is to ensure that no misleading SBAS data is provided by the GEO satellite. It compares the uplink messages received from the KUS SGS Core Computer with the downlink messages received from the receiver.
Developed under TAS-F Design Authority, which owns the IPR, the KUS SGS Signal Generator (SG) is part of the KASS Uplink Station as well. The main function of the SG is to generate the L1 and L5 RF signals which are used for uplink of SBAS correction data to the GEO stationary satellite. The code and carrier phases of these signals have to be steered for time synchronization and compensation of signal propagation effects.
The project covered the development of the complete hardware. The data processing was implemented on a FPGA. The specification, design and verification was conducted according to design assurance levels B (DAL-B) requirements. Detailed qualitative and quantitative analyses for reliability, availability, maintainability and safety (RAMS) have been performed. This included Failure Mode and Effects and Criticality Analysis (FMECA), Fault Tree Analyses (FTA) and Mean Time between Failures (MTBF) calculations.
WIth this project f.u.n.k.e. AVIONICS has shown its profound know-how and experience in developing challenging technical subsystems according to customers specifications. The resulting SIgnal Generator, in particular, is indeed the first European Signal Generator to enter the world of Satellite Based Augmentation Systems.
It is expected that these technical solutions will be used in the future for the realisation of similar implementation projects all over the world.
The 2020s have started now completely different from what we have expected. Our scheduled participation at the exhibitions in Madrid and Friedrichshafen were cancelled and the exciting meetings with customers, partners and suppliers will not happen in the near future.
Sun is shining, spring is coming and a great flying season could start now – at least for the next few weeks this will not be the case in many regions.
But also this phase will pass by sooner or later, maybe you take the new time gained in order to think about new avionics components for the cockpit, assuming that the flying season is not cancelled, but just postponed for a few weeks. Our company still runs in almost normal business mode and production, support and shipment capbilities are fully kept.
We wish you, our customers, partners and suppliers, all the best in these difficult times and hope for a better situation soon.
Even if you might hear it quite often at the moment: stay healthy and all the best to overcome this crisis.
Your team from f.u.n.k.e. AVIONICS GmbH
Die 2020s have started, f.u.n.k.e. AVIONICS thanks all our customers, business partners and suppliers and wishes all the best for the New Year 2020! We look forward to meeting you all again in the new decade.
Together with our partner Stangl Funktechnik we present our ground VHF radios (including our mobile VHF radio FSG8) from March 10 to 12 at the World ATM Congress in Madrid (booth 185). As every year we look forward to meeting you again later from April 01 to 04 at the AERO 2020 in Friedrichshafen. We look forward to a great flying season and wish always happy landings!
