SPAINSAT NG programme successfully passes Preliminary Design Review (PDR)

Important milestone successfully achieved on schedule despite Covid-19 Spanish industry assumes leadership of communications payload for first time, including integration of both satellites’ payloads in Spain Advanced technologies for Next Generation secu

The SPAINSAT NG programme, owned and operated by Hisdesat, has successfully passed the preliminary design review (PDR) of the payload and the full satellite, including PDR of Pacis 3 (PPP) elements. SPAINSAT NG is being manufactured by a consortium of four co-primes from Airbus in Spain and France, and Thales Alenia Space in Spain and France.

This important milestone confirms the soundness of the preliminary design and technical capabilities of the SPAINSAT NG satellite system.

Despite Covid-19 related challenges, the teams managed to achieve this milestone in the expected timeframe thanks to their commitment to continue working at full capacity, combining remote work with face-to-face activity in the workplace.

“Successfully passing the satellite and payloads PDR, including Pacis 3, in the planned schedule shows the outstanding commitment and performance of all the teams working in this challenging programme. I really appreciate the efforts of everyone, from our main end customer and partner in the SPAINSAT NG PPP: the Spanish Ministry of Defence, and the Spanish Ministry of Industry, Trade and Tourism as lender of the programme, to CDTI, ESA, Hisdesat, Airbus, Thales Alenia Space and the rest of the industry working on the programme”, said Miguel A. García Primo, Hisdesat CEO.

The SPAINSAT NG programme comprises two satellites, SpainSat NG I and II which will be situated in different geostationary positions to operate in X, military Ka and UHF bands.

The communication payloads of both satellites are provided by Spanish industry, including integration of the Communications Module in Spain, a major step forward for Spanish industry. Airbus in Spain is responsible for the X band payload, while Thales Alenia Space in Spain is responsible for the UHF and Ka band payloads. Other companies from the Spanish space industry are also involved. The UHF payload is a new development in Spain, positioning the country at the forefront of the few countries in the world with national systems in the military UHF band.

The satellites are based on the Eurostar Neo platform, Airbus’ new geostationary telecommunications satellite product, a significant evolution of the highly reliable and successful Eurostar series with an entire range of major innovations. SpainSat NG satellites include an X band fully flexible payload, employing active antennas with in orbit reconfiguration capability, an on-board digital processor that will interconnect the X and Ka band payloads for cross-banding, and a dedicated high speed service link enabling fast re-configuration.

“Spain has always been at the centre of our space activities and at Airbus we have a long history in providing payloads for Spanish government missions. This milestone represents an extraordinary achievement as it clearly validates that we have succeeded in further developing our expertise and capabilities on new technologies here in Madrid,” said Fernando Varela, Head of Airbus Space in Spain. ”We are now ready for the next stage and on track with integration of the communication modules in our clean rooms.”

“The successful PDR is an important milestone for the development of the SPAINSAT NG programme, which is on-track and on-schedule thanks to the huge professionalism and commitment of the project team,” said Eduardo Bellido, CEO of Thales Alenia Space in Spain. “For the first time we lead in Spain the development and integration of the payloads for a programme like SPAINSAT NG, which positions us at the forefront of space technology with the capacity to integrate large space systems. This will allow us to take the lead of new payloads and instruments in future missions.”

The development of SPAINSAT NG is supported by the Spanish Centre for the Development of Industrial Technology (CDTI) in the framework of a public-private partnership between the European Space Agency (ESA) and the satellite operator Hisdesat, called Pacis 3.

The ESA Partnership Project supports the development and integration of innovative satellite payload elements, such as the reconfigurable transmit and receive X-band active antennas, and the deployable pallet with individually steerable Ka-band antennas. The Partnership Project will de-risk the partners’ investments to answer market needs through the development of a sustainable end-to-end system up to in-orbit validation. It will also demonstrate novel pooling and sharing concepts to ultimately provide more affordable, flexible and secure communications services for governmental users in Europe.

“The Pacis 3 Partnership Project with Hisdesat is an important step within the Govsatcom Precursor project, part of ESA’s Space Systems for Safety and Security Programme” stated Elodie Viau, ESA’s Director of Telecommunications and Integrated Applications. “Pacis 3 shows how the European space industry can respond to a globally emerging market of secure satellite communications. Partnership Projects, provide an effective and collaborative environment to introduce innovative systems and services, up to in-orbit validation.”

The first of these New Generation SpainSat satellites will be launched at the end of 2023 and the second one a year later, guaranteeing the continuity of secure communications services.

The SpainSat NG satellites will have an operational lifetime of 15 years, remaining in service up to 2039.
