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.

Nathan Strout The U.S. Army has invested another $190 million into a counter-small unmanned aircraft system (C-sUAS), but it's determined that the system will need to be replaced by a U.S. Marine Corps alternative. On July 20, the Army announced it was awarding DRS Sustainment Systems $190 million to develop, produce and deploy the Mobile-Low, Slow, Small Unmanned Aircraft System Integrated Defeat System (M-LIDS). While the system will be deployed, it doesn't have a long-term future with the military. Despite the Army investing in the program for years, M-LIDS is a casualty of redundancy. As the Department of Defense has become more concerned by the threat posed by small drones in recent years, the services have each developed their own C-sUAS responses — mobile, stationary and dismounted. Recognizing the redundancy in that approach, the defense secretary delegated the Army to lead the effort to narrow the number of C-sUAS solutions for use by the joint forces. On June 25, the Army's Joint C-sUAS announced it had selected eight C-sUAS for future investment and deployment by the joint forces. M-LIDS didn't make the cut. But then, about a month later, the $190 million M-LIDS contract was announced, “Mobile-LIDS (M-LIDS) was not selected and will be replaced by the next generation mobile system,” said Jason Waggoner, an Army spokesman. In the meantime, “M-LIDS will be deployed with Army units to the CENTCOM area of operations.” M-LIDS would likely be replaced by the Light-Mobile Air Defense Integrated System (L-MADIS), a C-sUAS developed by the U.S. Marine Corps and the only mobile solution approved by the Joint C-sUAS Office. L-MADIS has already been deployed for testing and was reportedly used to down a drone off the coast of Iran last year. The Joint C-sUAS office told reporters in June that the services were conducting an analysis of how many systems would need to be replaced under the new arrangement. However, leaders were not able to provide a timeline for how quickly they expected to replace those systems. The series of announcements in this market came quickly this summer. Two days after the M-LIDS award, the Army announced a contract for one of the C-sUAS solutions that was included on the list for future investment: the Expeditionary-Low, Slow, Small Unmanned Aircraft System Integrated Defeat System (now known as FS-LIDS). The $426 million contract with SRC Inc. provides for the development, production, deployment and support of FS-LIDS, the only fixed-site solution approved for the joint forces by the Joint C-sUAS Office. “Development of FS-LIDS is complete and systems are being deployed to U.S. forces globally, with a focus in the CENTCOM area of operations,” Waggoner said. “FS-LIDS will remain in use until replaced with newer technologies.” C-sUAS spending hasn't been limited to the Army in recent weeks. On Aug. 10, the U.S. Air Force issued Black River Systems Co. an $89 million contract for an operational C-sUAS open systems architecture https://www.c4isrnet.com/unmanned/2020/08/13/army-buys-189m-counter-drone-system-but-already-has-plans-to-replace-it
