ANSPs and air defence jointly discuss surveillance data distribution

Frequentis Comsoft hosted the first Surveillance Data Distribution Solution Networking Group at the end of October to address user needs, exchange ideas and share current working practices with air traffic control and military organisations

The need to integrate an increasing number of surveillance systems, operating multiple, disparate systems can result in a situation where effective communications or data sharing is not possible. Replacing legacy systems is costly.  Frequentis Comsoft’s next generation of Surveillance Data Distribution Solution (SDDS-NG) bridges that gap, enabling all surveillance sensors, processing systems and other data users to connect seamlessly, organising disparate surveillance data services into a single infrastructure.

Multiple organisations from Europe took part in the networking group and the event began with a topical visit to the German ANSP Deutsche Flugsicherung (DFS) Area Control Centre (ACC) in Karlsruhe where participants could see first-hand how SDDS-NG plays a role in their daily operations.

ADS-B, MLAT & WAM

To boost efficiency, streamline operations, cut infrastructure costs and enhance safety, Air Navigation Service Providers (ANSPs) are looking at new technologies that can out-perform traditional radar for both air and ground surveillance. In many cases, they need to replace end-of-life radar systems, and would benefit from a lower-cost alternative.Two key technologies within the domain of Secondary Surveillance Radar (SSR) are multilateration (MLAT) and Automatic Dependent Surveillance – Broadcast (ADS-B).

To boost efficiency, streamline operations, cut infrastructure costs and enhance safety, Air Navigation Service Providers (ANSPs) are looking at new technologies that can out-perform traditional radar for both air and ground surveillance. In many cases, they need to replace end-of-life radar systems, and would benefit from a lower-cost alternative.

Two key technologies within the domain of Secondary Surveillance Radar (SSR) are multilateration (MLAT) and Automatic Dependent Surveillance – Broadcast (ADS-B). MLAT analyses tiny differences between the times at which signals are received by multiple small ground stations to determine an aircraft’s position with greater accuracy and precision than conventional secondary radar. ADS-B relies on aircraft to broadcast their position, identification, velocity, projected path and other useful information. MLAT is backward-compatible with existing SSR transponders and forward-compatible with ADS-B.

The Quadrant product from Frequentis Comsoft uses advanced MLAT algorithms to provide 3D position measurements, and offers lightweight, cost-efficient ADS-B sensors as a replacement for – or addition to – SSR. Highly flexible, Quadrant can scale easily and rapidly to support requirements from a single remote deployment to national Wide Area Multilateration (WAM). The system could also be used by a consortium of regional airports to centralise ATC to a single location for reduced costs.

Quadrant employs patented Simultaneous Tracking and Calibration (STaC) technology developed by Frequentis Comsoft to maintain system synchronisation, enabling increased accuracy and reduced dependency on GPS timing signals.

By supporting a more accurate and detailed Air Situation Picture, Quadrant can enhance airport safety for both ground and air traffic. The system has a field-proven capacity to maintain throughput even in severe weather conditions and low visibility.

With small, easily accessible sensors that contain no moving parts and that can be installed on existing structures such as roofs or mobile network masts, Quadrant offers the potential for significant reductions in lifecycle cost compared with conventional radar. It also enables airports to reach operational readiness faster and with less capital investment.

Surveillance Data Distribution

It is vital for Air Navigation Service Providers (ANSPs) and air defence organisations to ensure effective communication and data-sharing between surveillance systems. They must be in full control of the information flows and be able to apply comprehensive quality assurance to data, or risk losing situational awareness. With the number and variety of systems and standards constantly increasing, it is becoming more challenging for organisations to maintain their surveillance distribution environments.

They must be in full control of the information flows and be able to apply comprehensive quality assurance to data, or risk losing situational awareness.

With the number and variety of systems and standards constantly increasing, it is becoming more challenging for organisations to maintain their surveillance distribution environments. Newer technologies such as ADS-B and multilateration are becoming more common, and data volumes are rising exponentially, not least because of the proliferation of drone traffic. These developments further complicate the assurance of quality and safety in the surveillance data chain. Simply boosting network bandwidth and system processing power is not an adequate response: ANSPs need a centralised platform for integrating, monitoring, configuring and controlling any type of surveillance data, today and tomorrow.

With next-generation Surveillance Data Distribution Systems (SDDS-NG) from Frequentis Comsoft, ANSPs can bring all surveillance data services into a single infrastructure. The solution integrates data from any kinds of sensors and automatically converts data to and from standard and non-standard formats.

Available as a true turnkey solution, SDDS-NG enables ANSPs to continue to use legacy equipment and data formats while introducing newer technology from any vendor. This boosts cost-efficiency by extending the value of past investments, while reducing vendor-dependency for greater flexibility.

Field-proven in more than 35 major deployments operational globally since 2011, SDDS-NG offers exceptionally wide support for legacy and modern data formats and protocols. User-configurable data filtering – for example, by geography or by aircraft code – helps boost efficiency by giving each user only the information they need for their operational role, avoiding the potential for information overload. An integrated ADS-B server provides a coherent, rationalised air-situation picture by removing redundant information from multiple sources of overlapping data.

By harmonising data across disparate systems, SDDS-NG supports interoperability even across isolated systems based on proprietary standards. With a maximum transfer delay of 50ms, the solution also helps ensure currency of data for more accurate shared situational awareness. The layered solution architecture offers flexible connections with any vendor or generation of surveillance technology, and the solution supports comprehensive vertical integration with software-defined networks.

In addition to providing a single point of access and distribution for surveillance data, SDDS-NG enables centralised, cost-effective management. The solution is also highly scalable: organisations can deploy anything from a single remote-tower solution right up to a large, multi-node, fully redundant international network. Regardless of their individual scale, different systems can be managed centrally.

Surveillance Data Processing

The reliability and accuracy of surveillance data is critically important for safe and efficient Air Traffic Management (ATM). Losing access to surveillance data in one section of airspace can significantly reduce Air Traffic Control (ATC) capacity, putting pressure on neighbouring airspace. It is therefore vital for ATC organisations to exchange and make optimal use of all available sensor data. In particular, organisations in different countries must be able to generate and share a seamless, accurate and reliable Air Situation Picture (ASP).

It is therefore vital for ATC organisations to exchange and make optimal use of all available sensor data. In particular, organisations in different countries must be able to generate and share a seamless, accurate and reliable Air Situation Picture (ASP).

Creating a valid ASP in real-time depends on rapidly, reliably and accurately processing large volumes of diverse sensor and radar data in multiple different formats from multiple sources.

Since 1998, EUROCONTROL’s ARTAS (ATM suRveillance Tracker And Server) system is one of the most advanced and most successful tracking systems for ATC capable to produce a reliable, accurate and real-time ASP, and today is in active use in more than 43 ATC centres tracking almost 90 percent of air traffic in Europe.

Since 2001, Frequentis Comsoft is the industrial partner for EUROCONTROL’s CAMOS (Centralised ARTAS Maintenance and Operational Support), the maintenance and development service supporting EUROCONTROL’s ARTAS system. EUROCONTROL’s CAMOS has actively contributed to the success of ARTAS (e.g. it ensures the continued ARTAS maintenance and development in a SWAL3 manner).

Thereby Frequentis Comsoft has long since acted as a key development and support partner to EUROCONTROL for ARTAS, and, as well as deep expertise in surveillance tracking technology, Frequentis Comsoft has years of experience in the installation, configuration and tuning of ARTAS systems, and offers turnkey deployments of the technology.

Frequentis Comsoft is a EUROCONTROL-licensed ARTAS Distributor, and therefore authorised to deploy EUROCONTROL’s ARTAS systems for Non-EUROCONTROL Member State Organisations (NEMSO) upon agreement with EUROCONTROL, as well as to provide tuning, training and support services to NEMSO ARTAS End Users.

ATM Modules

The final link in the Air Traffic Control (ATC) surveillance chain is the presentation of accurate information to the controllers, giving them situational awareness of both air and ground traffic. As Air Navigation Service Providers (ANSPs) face up to the challenges of achieving efficient gate-to-gate operations, they are increasingly required to integrate information from multiple sources, and to present different views of this data to enable seamless switching between each phase of a flight.

The final link in the ATC surveillance chain is the presentation of accurate information to the controllers, giving them situational awareness of both air and ground traffic. The display component of any surveillance solution naturally plays a vital role in the safe and efficient management of aircraft both in the vicinity of aerodromes and en-route to their destinations.

As ANSPs face up to the challenges of achieving efficient gate-to-gate operations, they are increasingly required to integrate information from multiple sources, and to present different views of this data to enable seamless switching between each phase of a flight. At the same time, ANSPs are under pressure to reduce costs and enable greater flexibility in working practices, while reducing complexity at controller working positions. ATC must also cope with new potential safety threats arising from uncoordinated drone operations.

The Air Situation Display (ASD) product from Frequentis Comsoft provides a configurable, high-performance user interface for air traffic controllers and aerodrome flight information service officers. Designed by controllers, for controllers, ASD features an optimised, heads-up display that reduces workload and prioritises the most important information. Multiple ancillary windows complement and enrich the information shown in the main traffic window, keeping controllers focused on core tasks but also aware of supporting data – for example, weather conditions.

Built-in support for flight data handling enables controllers to create, edit and save flight plans, then match data against current aircraft tracks by callsign, Mode S address or Mode 3/A code. ASD features a highly adaptable functional model, enabling users to configure the system to meet their operational requirements and display preferences in tower, approach and en-route settings.

Plug-and-play installation and integration with both legacy and web-based environments helps ensure rapid, cost-effective deployment, and ASD’s modular architecture makes it easy to add functionality – for example SafetyNets features such as Short Term Conflict Alerts (STCA), Area Proximity Warnings (APW) and Minimum Safe Altitude Warnings (MSAW).

ASD can be used within a unified solution spanning multiple remote sites, and can scale from a single working position up to a distributed control and monitoring system with multiple data-acquisition and control-centre sites. Open interfaces and conformity to industry standards help future-proof the system, and there are no single points of failure across hardware, software or networking components.

Frequentis Comsoft also offers a range of tools to support surveillance, including R2D2-V2: a state-of-the-art system for the legal recording and replay of surveillance data, audio data, and screen content. Combined with the RMD‑V2 product, R2D2-V2 enables comprehensive post-event analysis and investigation.

To help ensure conformity to ASTERIX standards, Frequentis Comsoft offers its EUROCONTROL-qualified RAPS (radar analysis and playback system) product. RAPS – now in its third iteration – is a highly versatile tool that enables organisations to generate, test, analyse, filter, convert and validate surveillance data. System and radar engineers can use RAPS for system testing, fault analysis, quality monitoring and trouble shooting.
