July 2, 2020 - TNO has signed a contract with ESA to demonstrate cutting-edge optical communication technologies for future terabit-per-second telecom satellites. The TOmCAT project (Terabit Optical Communication Adaptive Terminal) will enable high-throughput laser communication between ground stations and satellites.
This project is Phase 2 of TOmCAT, which started in 2017. It brings together key players in the Space and High-Tech industries, including: TNO, Airbus Defence & Space Netherlands, FSO Instruments (consortium partner Demcon), Hittech Multin (NL), Celestia-STS (NL), MPB Communications (CA), Airbus DS SAS (FR) and Eutelsat (FR), SES (LU).
TOmCAT is a co-funded activity in which TNO, the companies involved, the Canadian Space Agency and the Netherlands Space Office invest through the ESAs ARTES Strategic Programme Line ScyLight.
Key technologies include high-bandwidth adaptive optics, thermally stable opto-mechanics, high-power photonics, and high-throughput optical transceivers.
TNO Space aims to enable secure broadband connectivity that will support the growing demand for data and increase communication efficiency. We also help stimulate economic growth in the Netherlands and Europe by enabling companies to realise new products, generate new business and improve their competitive position. TOmCAT is one example of these goals in practice.
HOW DOES TNO CONTRIBUTE TO TOMCAT?
TNO brings all parties together and integrates all expertise to:
1) Design the end-to-end Optical Feeder Link for high-throughput satellites.
2) Build and test cutting-edge technologies required for future Terabit Optical Ground Stations.
3) Build an end-to-end Optical Ground Terminal demonstrator and test it in a 10 km ground-to-ground link. This will show the technical feasibility of future terabit-per-second laser communication between ground and satellite terminals.
TNO considers development in the TOmCAT project to be a major and important step towards the realisation of commercial Optical Ground Terminals and Optical Ground Stations for high-throughput Optical Feeder Links.
Furthermore, TNO will work in the coming period, in parallel with TOmCAT phase 2, with Airbus Defence & Space Netherlands on business development and, in collaboration, position Airbus DS NL as future Original Equipment Manufacturer (OEMer) of these Optical Ground Terminals and Optical Ground Stations.
TECHNOLOGY AND APPLICATION
TOmCAT is a technology development project with the end goal of developing a commercial optical ground station product. With high-data-rate laser links, this ground station can communicate with the next generation of Very High Throughput Satellites.
One of the innovative elements of TOmCAT is its ability to pre-correct the laser light with adaptive optics. When light moves between the surface of the Earth and space, it gets distorted due to the fluctuations in the atmosphere. TOmCAT measures the distortion of the received laser light from the satellite, and by applying the inverse of this distortion to the transmitted light, a robust communication link can be established. In order to enable this, high speed adaptive optics is required. An important objective for the project is to build a demonstrator to test and prove this concept.

Tony Osborne June 22, 2020 Germany is set to become the first of the Eurofighter Typhoon partner nations to retrofit an active, electronically scanned array (AESA) radar, a move that should bolster the fighter's export potential. The German Parliament has given a green light for Berlin to spend €2.8 billion ($3.1 billion) to install the Euroradar consortium's Captor-E radar in all—around 106—of the German Air Force's Tranche 2 and 3 aircraft from around 2023. Contracts should be signed in the coming weeks. Hensoldt will be the design authority for the retrofit program Germany is receiving the Mk. 1 version of the Captor-E AESA Export customers will receive Captor-E first. Kuwait has ordered 28 aircraft, and Qatar 24, and a batch of Kuwaiti aircraft will be delivered this year. But program officials believe that with the AESA finally receiving partner nation backing, the Typhoon's chances in competitions closer to home may have moved up a notch. AESA-equipped Typhoons are proposed for both Finland and Switzerland. But the radar's capabilities could not be evaluated when the fighter took part in trials in those countries, as the participating aircraft were not fitted with it; its competitors were. All four Eurofighter partner nations, Germany, Italy, Spain and the UK, supported development of the radar, done by a consortium of Leonardo, Hensoldt and Indra, but have been reluctant to make the retrofit investment. That is due in part to budgets, but also reflects their satisfaction with the currently installed mechanically scanned Captor. The AESA, however, boosts radar performance and range, giving the aircraft a sensor that can match the performance of the MBDA Meteor beyond-visual-range air-to-air missile. A mechanical repositioner helps widen the radar's field of view to around 200 deg., from 120 deg. with the existing mechanically scanned radar. For the German retrofit program, Hensoldt will take a leading role in the production and delivery of the radars and act as the design authority, while Airbus will act as the test and integration lead. “With this decision, Germany is taking on a pioneering role in the field of key technology for the Eurofighter for the first time,” says Hensoldt CEO Thomas Muller. “It is a signal for Europe that Germany is investing in a technology that is of crucial importance for European defense cooperation.” Airbus Defense and Space CEO Dirk Hoke says the addition of the radar will increase the mission effectiveness of the aircraft and help integrate it with the Franco-German Spanish Future Combat Air System. Leonardo, which led Captor-E development, will provide support to Hensoldt in its role as design authority. Leonardo will also supply the radar's processor. Three different versions of the Captor-E have been developed or are under development. The German retrofit program calls for the installation of the Mk. 1 radar, which has been developed from the Mk. 0 radar that will be delivered to Kuwait and Qatar. The Mk. 1 adds new modes and a multichannel receiver. Along with being retrofitted to the German Tranche 2 and 3 aircraft, it also likely will be fitted to the 38 new-build aircraft planned under Berlin's Quadriga buy to replace its existing Tranche 1 Eurofighters, which lack the computing and electrical power for an AESA installation. Work has also begun on the Radar 2 being developed for the UK, which will feature an electronic attack capability. It is expected to enter service in the mid-2020s, and the UK plans to install it on its Tranche 3 model aircraft. Spain too is planning a retrofit program with the Mk. 1 radar, but also limited to its Tranche 3 fleet. Airbus revealed last November, however, that the novel coronavirus pandemic appears to have delayed Madrid's plans. An AESA has been part of the Eurofighter's development road map for around 15 years. The consortium had originally hoped that it could form part of the Tranche 3 fleet. The capability was also part of the consortium's ultimately unsuccessful offer for India. But it was not until 2014 that the first Captor-E development radar began flying in the aircraft, making an appearance at the 2014 Farnborough Airshow. The AESA radar capability is added through the Eurofighter's Phase 3B Enhancement (P3E(b)) package that will be delivered to Kuwait. Leonardo completed flight trials in support of the Mk. 0 radar development and P3E(b) in late May. Along with the Quadriga purchase, known in Germany notionally as Tranche 4, the country is also planning to use the Eurofighter, as well as the Boeing F/A-18 Super Hornet, to replace the Panavia Tornado fleet, although these plans are subject to parliamentary approvals that could come as late as 2022-23 (AW&ST May 4-17, p. 50). Egypt is also reportedly interested in purchasing up to 24 Eurofighters, possibly as part of a multibillion euro procurement from Italy that also includes jet trainers, helicopters and warships. https://aviationweek.com/defense-space/sensors-electronic-warfare/germany-first-modernize-eurofighters-aesa-radar
