The new Amazonas Nexus satellite launched by Hispasat, has Aicox Soluciones technology

The new Amazonas Nexus satellite launched by Hispasat, has Aicox Soluciones technology for control segment systems and will offer quality Wi-Fi on planes and remote regions.

 

Applause and cheers. The countdown carried out at the NASA base in Cape Canaveral (Miami, USA), was completed successfully during the night from Monday to Tuesday. The leading role corresponded to the Spanish company Hispasat after the launch of its high-performance satellite Amazonas Nexus, considered the most ecological of the moment. The spacecraft will advance to its orbit, which is expected to reach next August, using an electric propulsion system. To facilitate this displacement, the 4.5-ton mass satellite has lightened its weight compared to others of its kind. Among other details, the satellite giant is the first operator in the world that will balance the carbon footprint derived from the launch with the planting of a forest.

This task will be carried out through the company Sylvestris, in which Repsol and Hispasat participate. Specifically, there have been 1,200 tons of fuel consumed in the launch of the Falcon 9 rocket, from the SpaceX company, owned by magnate Elon Musk.

Company sources describe the event as “a new era in satellite communications”, since it will allow high-speed Internet access throughout the American continent, the northern and southern corridors of the Atlantic and as remote points as Greenland and the jungle. amazonian. Among other features, the satellite “is designed to offer high-quality connectivity on planes and ships and will effectively contribute to reducing the digital divide in Latin America in an agile and efficient way.”

The satisfaction of Hispasat and SpaceX, upon verifying that the launch of the carrier rocket works as expected, is also shared by other companies participating in the project. This is the case of the builder Thales Alenia Space (TAS), which has incorporated four Spanish companies into the process: TAS Spain (responsible for the production of the interface unit, multiplexers and filters); Sener (for the manufacture of filters, couplers and reception, transmission, navigation and remote control and telemetry antennas), GMV and Aicox, for control segment systems.

Jordi Hereu, president of Hispasat, acknowledges to elEconomista.es that “the Amazonas Nexus represents an important milestone in the development of the Hispasat project, since it reflects many issues of the strategy that we are carrying out. The Amazonas Nexus allows us to address new markets important and ascending, such as access to air mobility, connectivity with maritime fleets and access to new territories”.

Among other details, Hispasat will be the Greenland telecommunications operator. It is a new generation satellite that allows us greater flexibility because it has the Digital Transparent Processor (DTP) to adapt to new needs in the future. without a doubt, it is much more versatile than previous satellite versions to adapt to the technological changes that occur during its useful life”, he explains minutes before taking off on the flight to Miami (USA).

The financing of the project is valued at 80.7 million dollars from the launch contract, as well as the launch insurance and the initial operations in orbit of the Nexus, the latter granted by EXIM-Bank in the first operation that this entity allocates to the satellite sector since 2015. “Previously, Hispasat had signed the financing for the manufacture of the satellite with BPI France and a pool of four financial entities for an amount of 129 million euros,” they explain from the company.

The profitability of the satellite is guaranteed once, before the launch, it already has 60% of its capacity already commercialized. Among other businesses, the Amazon Nexus will offer “Internet connectivity on planes, which means for passengers to be able to establish video calls on transatlantic flights,” the same sources indicate. It will also provide coverage over the entire American continent, from north to south of the Atlantic and Greenland, and will allow the provision of next-generation telecommunications services linked to broadband connectivity in remote environments and air and maritime mobility. Among the programs that will be launched with the Amazonas Nexus, the Caramuel Project initiative stands out, which will allow Hispasat the first quantum key distribution (QKD) mission through geostationary satellites.

 

24 hour postponement

Uncertainty is part of satellite launches. No matter how much technology exists, it always depends on weather conditions, whose random variability sets the agenda for all projects. Hispasat suffered these contingencies in the early hours of last Sunday to Monday, with a launch due to “adverse weather conditions.” Finally, those responsible for the Space Launch Complex 40 (SLC-40) of the Space Force Station in Cape Canaveral (Florida), decided to delay the operation by 24 hours to execute it successfully, without the imponderal weather against it.

Integrasys Solutions for Government Applications in 2021 EDF Proposals: NAUCRATES and RFSHIELD

Aicox is part of the consortium of companies led by Integrasys to coordinate the “RF Interference Removal for Military Services based on Spaces Link”

The European Commission is supporting R&D projects through the program European Defence Fund (EDF) 2021, with almost €1.2 billion for Defence and R&D projects. INTEGRASYS has been selected as one of the companies for obtaining multiple EDF programs, and two projects, thanks to its defence expertise acquired over the years.

Integrasys will be coordinating RFSHIELD “RF Interference Removal for Military Services based on Spaces Link”. The project will take up to 30 months, until June 2025. RFSHIELD will ensure the protection of the SatCom services from intentional and non-intentional interferences, increasing the availability and performance of COMSATCOM/MILSATCOM services for military users. The reason why INTEGRASYS has been designated as coordinator is due to the current expertise that the company has in Interference Removal solutions, with its available CLEANRF product. The consortium of the project is formed by 5 companies, AICOX, MBS, and INGESPACE as INTEGRASYS’ partners, who are also specialized in defence capabilities.

The company has also been awarded NAUCRATES project, which is focused on microsatellites for Geostationary Orbit Surveillance and Intelligence. The project duration will be until December 2025, and the main goal is to design and demonstrate a microsatellite with less than 100kg mass, positioned in a stable orbit outside the GEO belt, as an in-orbit optical sensor with the capability to approach other objects in GEO to take centimetre level resolution images.

Integrasys is highly-oriented to defence solutions as the company is committed to contributing to innovation in this dynamic sector, so EDF 2021 is one of the multiple defence initiatives. “‘’We are very honoured to support defence with the rising threats from more allies nations and we look forward to supporting more missions in the future’’, says Alvaro Sanchez.

Gallium Nitride (GaN) Amplifiers in Multiple Carrier Operation

GaN amplifier technology has had a real impact on Block Upconverter and SSPA design for Satcom applications. And it’s a hot buzzword in the industry.

Terrasat have implemented GaN into several IBUC models where it is perceived to deliver benefits for customers. It brings advantages:

  • higher power density– delivering higher power in a smaller, lighter enclosure.
  • Reduced power consumption.
  • Cost reduction in some frequency band–output power combinations.

Terrasat Engineers have implemented techniques to compensate for the inherent nonlinearity of GaN devices. This has resulted in a significant reduction in the amount of output power back-off required to meet the MILSTD definition of Linear Power (PLin) which is the useable output power and standard for comparing BUC/SSPA output power performance.

Graph A

 

…significant reduction in the amount of output power back-off required to meet the MILSTD definition of Linear Power (PLin)…

 

 

 

 

 

Limitations that Deserve Respect

All technologies have their strengths and limitations. It is as important to understand the limitations as it is to know the advantages. With GaN devices, limitations can become evident in operations using more than one carrier. This is not to say that it cannot be used with multiple carriers. But GaN performs differently than GaAs or TWTA amplifiers with respect to multicarrier operation. There are two situations where this limitation should be respected.

First, with a GaAs amplifier, you typically see a relatively linear and continuous IMD3 improvement with output power back-off. Below in Graph A is an IMD3 plot for a 200W C IBUC R GaAs amplifier. (The purple line is the -22 dBc IMD3 part of the MIL-STD linearity definition).

Graph B

 

 

GaN performs differently than GaAs or TWTA amplifiers with respect to multicarrier operation.

 

 

 

 

 

GaN & GaAs Challenges

You can see from this plot that IMD3 with a GaAs amplifier decreases rapidly and in a fairly strong correlation to an increase in output power backoff.

With a GaN unit there is a different result. Please see the IMD3 plot below of a 200W Full Ku IBUC G GaN unit. Things start out fine, but the curve quickly starts to flatten. Then at about 6 dB back-off it hits a “floor”. It doesn’t get any better. This is a characteristic of GaN devices that cannot be overcome.

What this means is that there is a limitation to the quantity of carriers that can be accommodated.

The second limitation is a bit scarier. It only shows up in situations with widely separated carriers. By the MIL-STD definition, all manufacturers measure IMD at a 5 MHz offset for specifications shown on the data sheet. Graph C shows IMD products at wider offsets.

The red line is the defined -22 dBc IMD level. The other lines plot IMD above and below the test channels at saturated power and then with 1 dB of output power back-off. At the 5 MHz offset there is clearly no problem meeting the -22 dBc requirement. However, this shows how the intermodulation products are increasing in intensity as the carrier offset increases. Whereas logic from working with amplifiers would say that the further two carriers are from each other, the less they will interact, it turns out that the opposite is true with GaN devices. With carriers spaced more than 25 MHz apart, there will be intermodulation products that may interfere with other services.

Graph C

GaN technology, when implemented well, can provide many benefits in terms of size, weight, and power consumption

At Terrasat we strive to enable our customers to make informed decisions. One thing we do not want is for any of our customers to learn the facts only after they install and commission their terminal. As a general statement Terrasat Engineering advises caution in planning carrier spacing greater than 20 MHz.

In summary, GaN technology, when implemented well, can provide many benefits in terms of size, weight, and power consumption. It is prudent to take the multi-carrier limitations into consideration when determining what BUC to invest in for a site.

Please note that the manufacturers of the GaN devices are working on a next generation of devices that will mitigate these limitations. This information is applicable to GaN amplifiers available as of this writing and we look forward to improvements.
