Xilinx launches ‘industry’s first’ 20 nanometer space-grade FPGA chip

June 9, 2020 by Sam Francis Leave a Comment

Chipmaker Xilinx claims it has achieved “lift-off” with the launch of what it says is the industry’s first 20 nanometer space-grade FPGA for satellite and space applications.

Xilinx, which invented field-programmable gate array chips, says the new FPGA provides full radiation tolerance and ultra-high throughput and bandwidth performance for satellite and space applications.

The new 20nm Radiation Tolerant Kintex UltraScale XQRKU060 FPGA provides true unlimited on-orbit reconfiguration, over a 10x increase in digital signal processing (DSP) performance – ideal for payload applications – and full radiation tolerance across all orbits, says Xilinx.

European Space Agency to launch robot to clean up space

December 12, 2019 by Sam Francis Leave a Comment

The European Space Agency is planning to send a robot out into space to clean it of debris, which mainly consists of the countless satellites sent into orbit over the past few decades.

The vast majority of these “junk” satellites – communications, weather, military – have operational lifetimes lasting a few years – about five to 10 years, after which there is no system for bringing them back or clear them in any way. (See simulation of space debris around Earth below.)

Some have previously proposed to build robots that can travel to those obsolete satellites to perhaps fix them or make use of them somehow or at least maintain them so they are operational for longer, but that is an idea that is still in development, although also mentioned as part of ESA’s plan.

Second SpaceDataHighway satellite to launch in July

May 24, 2019 by Anna

The EDRS-C satellite, the second node of the SpaceDataHighway network (also known as EDRS), will be launched into geostationary orbit at 31° East on 24 July 2019 by an Ariane 5 launcher.

Once positioned above Europe, it will provide redundant back-up for the SpaceDataHighway system, double transmission capacity and be able to relay the data from two observation satellites simultaneously.

This second satellite will be joining EDRS-A which transmits the images of Earth acquired by the Copernicus programme’s four Sentinel observation satellites on a daily basis.

MDA recognized by Nasa for robotic servicing of International Space Station

MDA US Systems, a division of MDA managed by SSL, has been recognized by Nasa’s Johnson Space Center for its “outstanding support” of a robotic upgrade to the International Space Station’s power system which took place in January.

The MDA team based in Houston played a critical role in planning and validating the robotic maneuvering both before and during the mission.

Nasa JSC ground controllers used the 15-degrees-of-freedom Special Purpose Dextrous Manipulator (Dextre) arm to install six new 430-pound lithium-ion batteries in two power channel integrated electronics assembly pallets.

Dextre first removed 12 older and depleted 740-pound nickel-hydrogen batteries from the pallets, nine of which were put on the Japanese H-II Transfer Vehicle’s external pallet to burn up on re-entry with it.

Nasa places order with SSL for robotic spacecraft which will fix satellites in orbit

New craft will be used to service satellites out in space

Nasa has placed an order with Space Systems Loral for a robotic spacecraft which will go and fix satellites while in orbit.

Nasa calls it the Restore-L servicing mission, and it is designed to demonstrate the ability to extend the life of a satellite in Low Earth Orbit. Scheduled launch is in 2020.

The Restore-L spacecraft will use robotics to grasp, refuel and relocate an existing US government satellite already in LEO orbit with the goal of demonstrating tools, technologies and techniques that can be implemented on future government and commercial missions.

SSL to build low earth orbit satellite for new customer

April 26, 2016 by Abdul Montaqim

Space Systems Loral, a provider of commercial satellites, has been awarded a contract to provide a Low Earth Orbit (LEO) satellite to an undisclosed customer.

In addition to building the satellite, SSL will also provide the launch and will operate the satellite on orbit.

“Our production of innovative small satellites is growing in both size and diversity,” said John Celli, president of SSL.

SSL’s manufacturing facility for small satellite production provides lower cost and faster production time than has been typical for satellite manufacturing in the past. With this contract award SSL now has 21 LEO satellites under construction.
