The secure communications satellite SpainSat NG I has been successfully launched early this morning by a SpaceX Falcon 9 rocket from Cape Canaveral (Florida). An unprecedented milestone for the Spanish space sector.
The SPAINSAT NG program, owned and operated by Hisdesat Servicios Estratégicos S.A., comprises two satellites, SpainSat NG I and II. Thales Alenia Space, a joint venture between Thales (67%) and Leonardo (33%), together with Airbus Defence & Space, has led the execution and construction of both satellites, SpainSat NG I and its twin, SpainSat NG II, which will be launched this fall. The two satellites will be positioned in different geostationary positions to operate in X-band, military Ka-band, and UHF, providing coverage to two-thirds of the Earth’s surface, from the United States of America to Singapore. It will provide services for the next 15 years.
Thales Alenia Space in Spain has been responsible for the UHF and military Ka-band payloads and the integration of the Communication Module for the two satellites along with Airbus. The Communication Module is the main body of the satellite, which embarks the communication payloads that give purpose to the mission.
Specifically for this mission, the company built an assembly and integration clean room at its site in Tres Cantos, Madrid, inaugurated in 2021, where the Communication Modules of the two satellites have been integrated. These advanced cutting-edge facilities represent a qualitative leap in Spain’s space industry capabilities for the assembly and integration of large space systems, something within the reach of a few space powers worldwide.
Being the largest satellite system ever integrated in Spain, the SpainSat NG I Communication Module weights more than 2 tons and measures 6 meters high, and is fully equipped with cutting- edge technology in the field of space communications, comprising hundreds of sophisticated electronic units.
The company has also designed and manufactured in Spain, France, Italy, and Belgium over 200 of electronic and radiofrequency units that are an integral part of the communications payloads and the satellite’s telecommand and telemetry system. Among them are the UHF processor, the heart of the UHF-band payload; the Transparent Digital Processor (DTP) that interconnects the X-band and military Ka-band payloads; and the Hilink unit, responsible for providing a high-speed service link that will facilitate a quick reconfiguration of the payloads.
The SPAINSAT NG program
SpainSat NG I is one of the most advanced secure communications satellites in Europe and ranks among the most innovative in the world. It is expected to begin to provide services early in the second half of 2025 to the Spanish Armed Forces, international organizations such as the European Commission in the GOVSATCOM program, NATO, and other allied governments.
Its mission is to ensure effective command and control of Armed Forces operations over a large portion of the Earth’s surface, guarantee communication capability in theatres of operations lacking communication infrastructure, ensure secure governmental communications in any operational environment (air, maritime, land), and provide strategic space capabilities to third nations. The SpainSat NG satellites, which will replace the current Hisdesat communications satellites, Spainsat and XTAR-EUR, will be capable of providing secure satellite communications with maximum protection against interference or other threats, including a high-altitude nuclear event, with maximum flexibility thanks to its real-time software-defined payload.
