(17 August 2020 – BlackSky) BlackSky has announced it has completed initial system checkouts and has begun delivering imagery from its fifth and sixth satellites 58 hours after launch.

Taking full advantage of the advanced analytics offered by its Spectra AI platform, BlackSky is now providing customers high velocity insights that were previously unattainable.

In the first port image BlackSky captured, three images were collected in rapid succession over Port Elizabeth, South Africa, on August 10, 2020, at 11:31 a.m. local time. By analyzing these images, BlackSky is able to extract critical economic and financial indicators to offer a near-real-time view of commercial activity in Port Elizabeth. In particular, with the assistance of Spectra AI, BlackSky can count the number of container stacks in the container yard, identify the container and bulk carrier ships currently berthed, count the number of vehicles awaiting export in the car terminal, track ground vehicle movements, and even determine which cargo holds are actively being loaded.

“The rate and volume at which our customers are consuming global monitoring information is increasing dramatically,” said Brian O’Toole, CEO of BlackSky. “To help customers immediately access critical information, BlackSky has developed GEOINT technologies combined with machine learning to rapidly deploy and seamlessly integrate satellites into our product suite. The speed with which we were able to reach first light demonstrates our ability to move industry benchmarks forward so our customers are always the first to know.”

The addition of these satellites to the BlackSky constellation increases opportunities for intraday observation of customer targets and reduces decision-making timelines. In collaboration with satellite manufacturing partner LeoStella, BlackSky has an active assembly line delivering two satellites per month.

BlackSky’s latest two satellites were launched into an inclined orbit at 1:12 a.m. EDT on August 7 via SpaceX’s Starlink mission. The satellites provide panchromatic and color imagery with submeter resolution. BlackSky now has six satellites on orbit and plans to launch six additional satellites by the end of Q1 2021, advancing its dawn-to-dusk global monitoring capability.

RUAG Space has developed a new powerful computer for satellites

RUAG Space has developed a new powerful computer for satellites

(1 December 2020 – RUAG Space) RUAG Space has developed a new powerful computer for satellites called “Lynx”.

The development was achieved with the help of a contract from the European Space Agency’s program of Advanced Research in Telecommunications Systems (ARTES) and has been done at RUAG Space in Gothenburg, Sweden. “Our computer contains an extreme amount of power”, explains Anders Linder, Senior Vice President Electronics at RUAG Space. Lynx is 250 times more powerful than the normal On Board Computers, which RUAG currently delivers to ESA programs.

Computing power for Artificial Intelligence

“We have been very early with this development. This year, we are seeing that Artificial Intelligence and Machine Learning is starting to arrive in space development programs and now we have a computer ready that perfectly matches the requirements of these customers”, says Anders Linder. “Customers who want to do Machine Learning in space need a lot of computing power – which our computer can provide.” The Lynx On Board Computer will be qualified for space until end of 2021.

High performance, long life

The Lynx Single Board Computer is designed for a long life in any satellite orbit (e.g. 15 years in geostationary earth orbit) or spacecraft trajectory. The computer offers a high-performance processor, which is provided by an ARM processor delivering 30000 DMIPS (short for Dhrystone MIPS, a computing benchmark). “That is a huge leap forward in processing performance for spaceborne computers”, adds Linder. A powerful FPGA (field-programmable gate array) offers flexibility in terms of communication, interface and processing capability. The computer can be used on the platform or in the payload. For its entire electronics portfolio RUAG Space offers a direct technical interface to U.S. clients in its office in Denver, Colorado.

Origami antenna springs up for small satellites

Origami antenna springs up for small satellites

(1 December 2020 – ESA) A novel helical antenna that sprang from a container the size of a tuna can is now operational in orbit. Developed by Oxford Space Systems in partnership with ESA, this origami-inspired antenna is equal in length to the shoebox-sized satellite hosting it, part of a growing constellation of nanosatellites providing Internet of Things services around the globe.

This latest operational satellite from UK company Lacuna Space, was launched on 28 September into low Earth orbit. After launch, it underwent a series of in-orbit tests to establish it as part of Lacuna’s Internet of Things network.

As a 3-unit ‘CubeSat’ built up from standardised 10-cm boxes, the satellite is smaller and cheaper than traditional satellites, but can still pick up signals from battery powered ground-based sensors, small enough to hold in the palm of a hand. The mission is targeting Internet of Things applications such as agricultural and environmental monitoring as well as equipment and freight tracking – aided by its high-performance helical antenna.

This new antenna took shape through an ESA R&D project, supported by the UK Space Agency through ESA’s General Support Technology Programme (GSTP), preparing promising technologies for space and the open market.

“The Internet of Things is going to be one of the catalysts for the green revolution we all want to see – helping us monitor everything from air and water quality, to assessing pollution levels around factories, rivers and cities,” remarks UK Space Agency Chief Executive Graham Turnock. “These green technologies are being made possible by cutting edge inventions by UK space companies, like this new Oxford Systems antenna.”

“Until this project, no European-made antenna of this kind was commercially available,” explains project technical officer Benedetta Fiorelli of ESA’s Antennae & Sub-mm Waves section.

“Having identified this gap in the market we proposed addressing it to various funding schemes, and it was GSTP that gave us the chance to take the idea forward. The result, little more than a year after the project started, is a tangible product already operating in space.”

CubeSats are growing in popularity because they draw maximum benefit from the latest miniaturised commercial-off-the-shelf components, to do more with less. But antennas are one satellite subsystem that cannot easily be shrunk down in size.

“We hit hard physical laws that link the size of the antenna’s radiating element with the frequency being used,” adds Benedetta. “So it becomes a challenge to accommodate the antenna aboard a small platform and still do useful work. For instance many CubeSats use simple thin wires antennas deploying from satellite bodies.

“But their performance is not optimal for Internet of Things type applications. Helical antennas are an inherently flexible design with many more parameters that can be tuned precisely as required – the antenna radius, number of spirals, pitch angle and so on.”

Founded in 2013 and based at ESA’s Harwell space campus, Oxford Space Systems has its focus on small, light satellite booms and antennas, to be folded away tightly before launch then spring to full size in orbit, origami-like.

“When we started working on deployable helical antennas we looked at which companies might be interested in that, and Oxford Space Systems was high on the list,” says Benedetta. “We engaged on the GSTP side while the company gained the support of their national ESA delegation, allowing the project to happen.

“It’s a good example of the role ESA should play: we identify a technology gap while industry spots a market opportunity, then we support industry in responding to it. The bulk of the work was done by Oxford Space Systems, including physical properties, radio frequency and deployment testing – slowed down somewhat by this year’s COVID-19 restrictions.”

Midway through the project, the company found a customer for their product, in the shape of Lacuna Space, a Harwell neighbour. Since then a second antenna has also flown, aboard another Lacuna CubeSat launched from India earlier this month.

“Even if it was in our plan since the beginning, I was surprised when they told me,” says Benadetta. “Activity sped up significantly during summer due to this flight opportunity,. In space terms that’s a fast turnaround to go from starting a project to a product working in space, so all involved are proud of it.”

Sean Sutcliffe, CEO of Oxford Space Systems, comments: “This represents a key milestone for OSS as it continues to execute the strategy to be the leading global deployable antenna company for space. Not only is this our first successful deployment of an antenna, but our second successful hardware deployment this year and our fourth in total. We continue to develop and deliver our range of antenna products which give leading performance capabilities with low launch mass and small stowage volumes.”

The satellite platform and early operations have been supplied by nanosatellite integrator NanoAvionics, with the payload developed and tested by Lacuna Space.
