ESA’s JUICE moving expeditiously to the Jovian system

On April  14th, 2023, at 09:14 a.m., local time, an Ariane 5 launcher  operated  by  Arianespace successfully lifted  off from Europe’s  Spaceport  in Kourou,  French Guiana, carr ying the  European  Space Agency  (ESA)  JUICE space probe, built  by  Airbus  Defence and Space.

JUICE will spend at least three years making detailed observations of the planet’s icy moons: Europa, Ganymede and Callisto, and will arrive at the Jovian system in July of 2031.

JUICE will study these moons as potential habitats for life and will address two key questions: what are the conditions for planet formation and the emergence of life, and how does the solar system work ?

The propulsion system for the JUICE spacecraft was developed, built, and integrated in Germany by ArianeGroup’s Orbital Propulsion teams, and is comprised of the 400 N main engine that will be used for the Jupiter orbit injection, 20 small thrusters, and two titanium propellant tanks.

After this mission, one Ariane 5 launch remains before Ariane 6 (artistic rendition below) takes up the baton, supporting Europe’s institutional missions and meeting the rapidly growing needs of the commercial market.

The Ariane 5 heavy-lift launcher is an ESA program carried out in cooperation between public institutions and industry across 12 European partner countries.

ArianeGroup is the lead contractor for the development and production of Ariane 5, as well as being responsible for launcher preparation operations up to lift-off. As prime contractor for Ariane 5 and Ariane 6, in charge of development and production, ArianeGroup is at the head of an industrial network comprised of more than 600 companies, including 350 small and medium-size enterprises (SMEs).

ArianeGroup delivers a flight-ready launcher on the launch pad to its subsidiary, Arianespace, which markets and operates Ariane 5 from Europe’s spaceport in French Guiana. During launch campaigns, Arianespace works closely with the CNES, the French space agency, the design authority for Ariane 5 and responsible for the satellite preparation facilities and the launch base.

“Arianespace is honored to have been entrusted with this launch, the first European mission to Jupiter, and to play a part in expanding our understanding of the solar system and the necessary conditions for the emergence of life. In preparing for this mission, we have worked hand in hand with ESA, Airbus Defence and Space, ArianeGroup, and French space agency CNES. I take this opportunity to thank all the teams who have given so much for 10 years to bring us to today’s successful result. And good luck to// JUICE for the incredible journey it is about to embark on.”
— Stéphane Israël, CEO of Arianespace


Kratos debuts their integration-ready OpenEdge™ Digitizer

Kratos Defense & Security  Solutions, Inc.  (Nasdaq: KTOS) has released their OpenEdge™ 2500 digitizer that is specifically designed  to help satellite  antenna makers digitally enable their products.

When integrated into any antenna, the compact digitizer reliably converts radio frequency (RF) signals into Internet protocol (IP) data streams that are easily consumed for use in modern, software-defined, communications networks.

The OpenEdge 2500 enables digitization to occur natively within nearly any parabolic, electronically steerable, or flat panel antenna. Today, when digitization is done at all, it occurs within a separate, added network component located either at the gateway, at the remote user terminal or somewhere in between. For both accuracy and transport efficiency, however, it is best to digitize as close to the signal’s origin as possible, and there is no place closer than within the antenna itself.

Cobham SATCOM will be the first to integrate the OpenEdge 2500 into its Comms on the Pause (COTP) SATCOM Tactical Terminals as well as other parabolic and flat panel electronically steerable antenna (ESA) terminals for maritime and land applications. Cobham SATCOM has considerable prior experience in the development and integration of digitization in its product lines and is an ideal partner to introduce the OpenEdge 2500.

The OpenEdge 2500 easily and effectively transforms traditional satellite antennas into digital ones, streamlining operations and allowing satellite service providers far more flexibility in configuring the best terminal solutions to meet their customers’ needs.

Specifically, the availability of digital-ready antennas will provide network operators with an additional path for migrating to software- enabled (SE) terminals.

SE terminals replace the purpose-built, proprietary equipment used at the network’s edge today with generic off-the-shelf compute, placing far more application power and security directly in the user’s hands.

The OpenEdge 2500, like all Kratos OpenSpace® products, is based on industry standards, including the DIFI interoperability standard, enabling seamless integration with other standards-compliant devices and virtualized network functions from other vendors.

Other advantages of the OpenEdge 2500 that will help antenna manufacturers better support their customers, especially when compared to alternative digitization equipment and processes include:

Increased operational efficiency. Operational integration occurs at the board level as an embedded component within the antenna. As a result, the OpenEdge 2500 does not require its own space, power or temperature control, or a separate enclosure.

• Low Size, Weight, and Power (SWaP)
The OpenEdge 2500 was designed for maximum per formance at the far thest edge of the network. At less than an inch tall, the OpenEdge 2500 is less than 
one-third the size of today’s smallest digitizers and architected specifically to fit most antenna form factors, with alternate configurations for unique platforms coming.

• Rugged Design
The OpenEdge 2500 can withstand shock, vibration, wide temperature and humidity ranges and other environmental factors, making it ideal for terminals on the move or in contested or challenging locations.

• Native BUC and LNB Support
Power and frequency references are supplied automatically from the OpenEdge 2500, enabling streamlined operations with any needed signal- enhancing equipment such as Block Up Converters (BUC) or Low Noise Block Converters (LNB).

• WGS ready
The OpenEdge 2500 is built ready to work with Wideband Global SATCOM Satellites (WGS), the backbone of the U.S. military’s wideband satellite communications capability. WGS provides worldwide, high-capacity communications for U.S. Government Agencies, the Department of Defense (DoD), international partners, and the North Atlantic Treaty Organization (NATO).

OpenEdge products are part of Kratos’ OpenSpace® Platform, supporting Kratos’ ongoing effort to bring satellite services into the communications mainstream by digitally enabling ground systems to operate seamlessly with today’s wireless and terrestrial networks.

“Digitization offers much needed flexibility and opens up new ways to drive forward satellite communications. As one of the first antenna manufacturers to join the Digital IF Interoperability (DIFI) Consortium, we have long promoted standards-based digitization for the next generation of multi-orbit, multi-domain and multi-network terminals and gateways into the digital age. Adapting and optimizing the OpenEdge 2500 will allow us to deliver much desired digital-ready capabilities to both government and enterprise users, whether on COTP terminals deployed in the electronic battlefield, or to New Space and research organizations at the forefront of signal processing, virtualization, and cloud connectivity.” — Bob Potter, TRACKER CTO at Cobham SATCOM

“Digitizing at the antenna is the critical first step in the digital transformation of satellite ground systems. With digital antennas powered by the OpenEdge 2500, antenna manufacturers can help their customers get fast, assured data transport over any IP network. They can also provide their customers with the ability to leverage IP networking and cloud architectures and fully virtualized and orchestrated operations to achieve their business goals.”
Kevin Tobias, Director of Edge Product Management at Kratos
