The objective of the ESA MENOS Evolution project is to develop a coherent end-to-end IP network for multimedia exchange over satellite capable to support HD, Hybride services and broadcast work flows.
The aim of this study is to identify and evaluate innovative multilayer solutions involving GEO satellites, LEO/MEO constellations and High Altitude Platform Systems (HAPS) to provide internet for all services.
A detailed model of the preferred solution has been realised and simulated to evaluate the performance of the multi-layer system showing the interest and complementarity of the different layers.
The project completed the design and manufacture of an Engineering Qualification Model (EQM) of a Feed Block Assembly (FBA) for future Ka Band Single Feed Per Beam (SFPB) antenna programmes.
Through the Artes-34 R&D project “TTC” with ESA, Norspace has developed and qualified three different EQMs. These are a Command Receiver (Rx), a Beacon Transmitter (Bx) and a Telemetry Transmitter (Tx). In addition a 31dBm Ku Band output amplifier module has been qualified under the frame of this contract.
This has been an important and strategic activity for Norspace, and this development project has established the company as a provider of TTC equipment for space.
The main strategic and technical objectives have been met, and commercial orders for flight models of Beacons, Transmitters and Command Receivers have been signed. This success shows that this program has been very useful and demonstrates an efficient use of ESA funding.
In this project, an efficient spectral monitoring concept design will be bread-boarded and validated using realistic in-space spectral sensing scenarios. Dynamic sensing within the C-, Ku-, Ka-bands are targeted, considering integration in commercial satellites with minimal impact in terms of size, weight, power consumption and complexity. This project targets a proof-of-concept architectural design and not a direct equipment design.
Flexible payloads in correlation with the raise of interest for C-band multibeam payloads due to frequency spectrum scarcity are emerging. Customers are currently considering the potential use of multibeam solutions for the replacement of ‘conventional’ solutions generating large beams. One of the main challenge is to develop the antenna configuration and associated feed clusters.
The study investigated various Optical Beamforming Networks (OBFN) and associated optical techniques and technologies to satisfy the mission scenarios and requirements developed during the initial part of the study.
Two options were identified as the promising option to investigate further and detailed design of these two options were investigated.
LNAFIN Oy implements a Q-band LNA according to ESA specifications. The unit is waveguide packaged, and its specifications include NF=2.5 dB, gain >30 dB and better than -18 dB wideband matching.
NanoSpace has under this contract continued to develop a gauging system to predict the residual propellant on-board satellites in orbit. The target market is medium and large satellites in Geo-synchronous orbits. The main value lies in capability to predict end-of-life with high accuracy – for a typical satellite down to a few weeks. A first engineering model has been designed, built, and tested together with propellant tanks up to 368 litres within this contract. Test results have demonstrated accuracies between 0.07% to 0.35%, depending of amount of gas injected. Test results compared with EcosimPro-simulations shows excellent agreement.
The objective of this activity was to increase the robustness and speed of the EEE parts procurement and testing of the Regys20 gyrometer for space applications. This comprised of 2 main work packages: i) EEE parts procurement transfer from Syderal to Sagem, through a CPPA (centralized parts procurement agent), and ii) the robustification of the testing process. This latter WP consists of 4 main points of improvement:
- 2 additional two-axes rate tables were qualified to avoid a bottleneck in the AIT process
- The EEPROM management process was enhanced with multiple checks to avoid human operator error and detect read/write errors
- The calibration process was robustified to automatically detect out-of-family-behaviour
- The test sequence was automated to allow weekend and night-time automated testing and save considerable time.
The combination of the above 2 WPs has considerably increased the competitiveness of the Regys20 and increased the robustness of the AIT process.
The design of a T/R Ku-band electronically steerable antenna based on a horizontal integration has considered various approaches, covering both technological and system aspects, enabling the realization of a low-cost architecture. The antenna uses the available aperture for both Tx and RX functions and the RF components are integrated in a single horizontal board which allows an effective manufacturing process and avoid the need for complex mechanical structures and RF connectivity.
The objective of the study is to develop and validate a digital test bench for use during AIT and IOT for all C-band to Ku-band payloads, exploiting innovative and rapid RF test techniques to significantly reduce the overall test schedule. Furthermore extension to Ka-band payloads and RF interface using optical fiber are designed.
In the frame of this activity an innovative Ku-band high power reconfigurable multibeam broadcast antenna has been designed, with the development and test of a demonstrator model. The most promising payload solutions suitable to support the present application in terms of both antenna configuration and front-end architecture have been identified and investigated in detail. This extended trade-off activity led to an innovative antenna solution consisting of a Confocal antenna configuration fed by an aperiodic feed array.
The designed Confocal antenna architecture, associated with sparse/aperiodic array feeding system, creates an innovative approach capable to fulfill the reconfigurable regional coverage mission in Ku-band, with full array operation and then full reconfiguration capability, full power allocation flexibility and graceful degradation, minimizing the number of controls.
The objective of this ARTES3-4 project is to study and to design a multi-reflectors pallet antenna. This new antenna product is envisaged to generate several coverages from one antenna structure and one single deployment. The design drivers of the product are the capability to accommodate several reflectors from 2 to 5, with different diameters varying from 1600mm to 900mm, a focal length varying from 1.9m to 3.2m. The reflector mounted on the pallet shall be able to operate in Ku and Ka frequency bands, and to realise mono beam and multibeams misions. Moreover, the pallet product shall be compatible of small launchers and several platforms like Spacebus, Eurostar and Alphabus. This antenna should be accommodated in double deployment. All these characteristics are considered to design this new product.

For now several years, the RPAS (Remotely Piloted Aircraft System) insertion issue is a very hot topic both in the US and in Europe, and the Command and Control (C2) link is one of the most important technological challenges to be addressed.
Regulatory and standardization bodies (especially ICAO, EUROCAE, JARUS) are making progress on this topic. Nevertheless, the work in front of us is still significant.
CERES study aimed, generally speaking, at supporting this effort and, in particular, at fostering the development of an adequate framework for the development of an appropriate C2 link satellite communication capability, by analysing the potential performances and security requirements as well as standard needs.
Furthermore, CERES complemented this top down approach by a bottom up approach, via the analysis of potential satcom candidate systems wrt. these requirements and needs.
The project is composed of 3 topics aimed to improve harness mass, cost and performances:

The objective of the project was to identify the best potential opportunities for European satellite service providers to engage in service delivery over integrated satellite and terrestrial networks.
Composite overwrapped pressure vessels are difficult to inspect for damage, particularly with respect to stress-rupture, creep and damage fibres embedded within the epoxy resin composite. To mitigate this risk of failure due to undetected damages, tanks are manufactured with significant margins and are thus “over engineered” in terms of flight needs. The project’s aim is to design a demonstrator of health monitoring system capable of detecting potentially dangerous damages and thus increasing safety of the vessels. The monitored vessels could be subsequently manufactured with smaller margins which result in their lower weight and reduced operation cost.
