ALTYS has recently launched a new solution for testing VHF-based data link functions. POCKET is a lightweight, portable, and cost-effective set for checking the VHF connectivity (ACARS, VDL2, or ATN) of an installation, whether aircraft or ground-based.
POCKET validates the installation of next generation communications systems – including CPDLC, ADS-C, DCL, and D-ATIS – providing quick PASS/FAILED indications. In case of connectivity failure, POCKET helps identify the fault segment and expedite the troubleshooting process. Airlines as well as avionics and ground system manufacturers will now be able to check data link function more easily than ever with POCKET.
The unit has wider-reaching capabilities than similar systems available in today’s aviation market – offering the ability to test all data link functions – but is much lighter, smaller, easier to use, and more affordable. The unit is composed of a compact radio transceiver, a mini antenna, and a tablet embedding ALTYS’s communication systems and test application.
Forthcoming product releases will support aircraft SATCOM functions testing as well as surveillance systems testing capabilities, including Mode-S transponders, ADS-B transponders, and TCAS.

ALTYS Technologies has unveiled SAGA to the international airport and ATC community during Airport Show in Dubai last May. SAGA is a turnkey solution for collaborative airport surface management that provides ATC and airport operators real-time visibility over airport surface and terminal area movements, as well as advanced statistics, reports, and alarms.

SAGA can be used either with an existing surveillance infrastructure or with ALTYS’s ASTRA ADS-B ground station and MLAT system.

SAGA provides a means to ensure safer airport operations through enhanced situational awareness – as well as heightened efficiency through better information-sharing among airport stakeholders. ALTYS developed SAGA in response to airports’ growing need to accommodate increased traffic flows despite infrastructure constraints.

Designed for use both by airside teams and strategic management, SAGA heightens users’ awareness over surface operations and provides quantitative performance indicators. SAGA allows users on airside operations teams to visually track aircraft – whether on the airport surface or in terminal area – as well as airside vehicles. The system’s interactive and collaborative web application allows a wide range of airport stakeholders to synchronously receive real-time updates and alarms, such as runway incursion, temporary exclusion zone incursion, and conflict risk alarms.

In addition to its real-time features for airside teams, SAGA boasts sophisticated analytics-generation capabilities in support to strategic management. The system provides operational monitoring and custom reports for in/off-block times, landing/take-off times, taxi in/out times, runway occupancy times, and airport segment utilization statistics – among others. SAGA’s KPIs help airport stakeholders come to informed decisions regarding challenging long-term operational situations, such as standard taxi route modifications and airport improvement projects. It also provides airport operators with an independent and reliable source of information to automatically generate timely and accurate airline invoices. 

SAGA incorporates a Data Fusion system to integrate surveillance data flows (ASTERIX format) from multiple airport surveillance sources: SMR, ADS-B, and MLAT. It additionally processes data from other systems such as ACARS and ATC data link communications. It is flexible to integrate with existing surveillance infrastructures, or ALTYS’s ADS-B ground stations and multilateration system.

 “We have worked closely with airport operators throughout the design and development process to best meet the end user’s needs and make SAGA as easy-to-use as possible,” says Patrick Rahmoune, Head of Monitoring and Data Engineering at ALTYS. “SAGA can be smoothly deployed at any airport Operational Control Center or Controller Working Position, and offers 24/7 web access over a secure server application. It is currently undergoing operational trials at a number of international and regional airports.

The SESAR project AGATHA – part of SESAR WP-E: long-term and innovative research – was successfully concluded early this year, led by ALTYS alongside ENAC (Ecole Nationale de l’Aviation Civile) and M3 Systems. The project proposed detailed technical recommendations to enable the smooth integration of General Aviation (GA) into the SESAR concept. The General Aviation sector currently lags far behind Commercial Air Transportation in terms of CNS capabilities – representing a potential barrier to harmonization in the European ATM system.
The AGATHA project’s main objective was thus to consider the feasibility of applying the latest wireless technologies to General Aviation to support a wide range of SESAR-compatible CNS/ATM applications and concepts, allowing aircraft to operate safely in a “connected” mode – all at an affordable cost. Following a round of consultations with stakeholders from the international General Aviation community, the AGATHA team identified operational priorities for GA and assessed CNS technologies’ ability to meet them.

The cellular communications system “Aero-LTE,” complemented by the Aeronautical Ad Hoc Network for Civil Aviation (AANET) – which functions via inter-aircraft links – proved promising for GA. The project proposed a navigation system for GA based on a GNSS system associated with SBAS (satellite navigation). And the team recommended a combined surveillance and anti-collision system that supports ADS-B and ACAS-X functions. All the systems recommended by the project team depend on low-cost and flexible RF infrastructure based on SDR technology, and use multi-mode, multi-channel antennas.

“The research we have done as part of the AGATHA project is an important first step towards the future GA cockpit – conceived and designed primarily in the interest of General Aviation,” says Kanaan Abdo, CTO at ALTYS Technologies. “Over the course of our discussions with the AOPA (Aircraft Owners and Pilots Association) and other GA stakeholders, we have gained an important understanding of specific requirements in order to offer the most relevant solutions. Precisely, this project has taken into account cost, size, and weight constraints in order to best adapt solutions offered to GA.”

Over the last several years, French test solutions provider ALTYS has seen global demand increase from a range of different aviation stakeholders for its data link infrastructure and avionics test equipment used for validating aircraft Controller to Pilot Data Link Communications (CPDLC). The company has progressively been supplying test equipment to both the FAA for its Data Comm program and the Single European Sky ATM Research Joint Undertaking (SESAR JU) for its ongoing study of data link communications issues in Europe. Airframe manufacturers and systems integrators looking to validate their onboard CPDLC avionics before entry into service have also turned to Altys for lab-based testing data link testing activity.

The main test equipment supplied by ALTYS to provide airports, operators, regulatory agencies and research consortiums a third-party means of validating their data link infrastructure equipment and services is the PEER platform and DREAM system. PEER has the ability to emulate either an aircraft sending and receiving standard data link messages to ground automation systems. The PEER technology is also capable of emulating a network of VHF data link ground stations, such as VDL 2, Aircraft Communications Addressing and Reporting System (ACARS) and Aeronautical Telecommunications Network (ATN) ground networks. ALTYS has primarily positioned its PEER test equipment to provide a method for performing comprehensive data link communications system integration testing in a lab environment.

“In addition to PEER we are currently providing our DREAM system in the Americas for the advanced modeling & testing of data communications equipment in a highly realistic environment. DREAM supports the emulation of thousands of aircraft and widely-deployed ground infrastructures (continent-wide), all of which operate fully standard-compliant systems that have been qualified against legacy ground networks and avionics,” Carlos Gonzalez, director of business development for the Americas at ALTYS, told Avionics Magazine.

The FAA has also used the ALTYS distributed and automated aircraft simulation platform, AC-SIM, at its Data Comm network services test bed located at its technical center in New Jersey. AC-SIM has the ability to simulate aircraft performing up to 8,000 flights for test runs lasting several days during which thousands of CPDLC messages can be exchanged, and the ground systems receiving them can be validated.

In Europe, SESAR JU has also used ALTYS test equipment to study the technical issues that have delayed the European mandate for aircraft CPDLC equipage until 2020. Earlier this year, SESAR JU published a report, which found that VDL Mode 2 over a single frequency has already reached its capacity limits and the development of next generation data link technology is going to be necessary to manage projected air traffic growth in Europe. 

Elsewhere in Europe, Dassault Aviation is also using ALTYS’s Commercial off The Shelf (COTS) test solutions to support system integration and validation testing of CPDLC avionics on its new Falcon 5X and 8X programs. Both the Falcon 5X and 8X will be equipped with Dassault’s Easy avionics suite and enhanced graphical CPDLC functionality.

ALTYS also recently achieved its first international deployment of MICRA at Miami International Airport, which is reflective of the wide-ranging capabilities of its various test solutions that go beyond basic send and receive validation testing.

“MICRA is a digital radio receiver that provides the ability to capture all information transferred over VHF data link and 1030-1090 MHz surveillance systems, such as Secondary Surveillance Radar (SSR), Mode S, Automatic Dependent Surveillance Broadcast (ADS-B), and Traffic Collision and Avoidance System (TCAS). MICRA is cloud-connected with ALTYS’s COSMOS system through an Internet Protocol (IP) Wide Area Network (WAN) connection to a Central COSMOS server. The COSMOS system provides real-time and fully Web-based access to advanced analytics, tracking, alarms, and Key Performance Indicators (KPIs) to monitor communication, navigation and surveillance systems performance,” said Gonzalez.

MICRA was deployed in Miami to support Air France Industries KLM Engineering subsidiary Barfield, to streamline its maintenance operations. Another 15 MICRA units have also been deployed in Europe to support monitoring activities for a number of airspace operators. The receiver can simultaneously process VDL2 data over up to four frequencies.

Going forward, Gonzalez sees demand increasing for its third-party testing technology used for more Communications Navigation and Surveillance (CNS) testing and validation, as both the Single European Sky and NextGen programs continue to evolve.

“The current growing sophistication of CNS systems used for aviation means there is a growing need to significantly increase validation efforts, as well as to develop equally sophisticated testing environments. We see an increasing demand for reliable, third-party testing solutions that offer a near-operational environment and an unrivaled level of realism and sophistication with regard to testing capabilities,” said Gonzalez.
