Maxar to study future systems for space-based comms for NASA

Maxar Technologies (NYSE:MAXR) (TSX:MAXR) has been selected by NASA to study future systems that could revolutionize NASA’s space-based communications architecture through innovative technologies and commercial partnerships.

The future architecture would be used for scientific and human exploration missions in Earth orbit, at the Moon, and throughout the solar system beginning in the mid-2020s.

NASA’s Space Communications and Navigation Program currently offers space-based radio frequency communications services for all of the agency’s space communications activities via its Space Network. The Space Network consists of a constellation of geosynchronous satellites called TDRS and ground systems that operate as a relay system between satellites.

Leveraging current and planned commercial communication and navigation infrastructure, Maxar will study concepts to augment the Space Network with more advanced optical communications capabilities and enhanced radio frequency services.

Maxar will also study a framework that allows for a transition from government-owned and managed space services to commercially developed and operated services.

This future architecture could unlock the promise of human exploration, new and greater scientific discovery, and reduce development and operations costs for future missions through improved communication and navigation services.

Maxar has decades of experience in developing systems for space communications.

The company has built some of the world’s highest capacity spacecraft, including JUPITER™ 1/EchoStar XVII and JUPITER 2/EchoStar XIX — which power HughesNet® high-speed satellite internet service across the Americas.

Maxar is currently building JUPITER 3, which will provide more concentrated capacity over high-use areas than any other satellite.

Maxar has also contributed advanced concepts for the U.S. Air Force’s next-generation protected satellite communications architecture and has built more than 280 satellites, with 91 commercial communications satellites currently in service.

The operations of DigitalGlobe, SSL and Radiant Solutions were unified under the Maxar brand in February; MDA continues to operate as an independent business unit within the Maxar organization.

Megan Fitzgerald, Maxar’s Senior Vice President and General Manager of Space Solutions, said this award highlights Maxar’s ongoing commitment to the development of innovative space solutions that will open up a new realm of possibilities for human exploration. This future architecture will be designed to yield significant development and operations savings over government-owned systems and will also provide the benefit of frequent technology advancements.

Earth to Sky smallsat to launch with Delta Satellite Solutions

Earth to Sky, Inc. (ETS) has inked a definitive launch services agreement with Delta Satellite Solutions, Inc. (DSS) — the launch will occur in March 2021 to 550 km. SSO and will place 120 cubesats on-orbit.

Delta Satellite Solutions is a provider of affordable rides and payload and satellite integration services for academic institutions and was founded with the intention of connecting the STEM world to engage in real world experiences for space exploration.

Many universities and high schools provide the experience of designing, developing, and creating smallsats but few have the opportunity to put them in space.

Chris Barker, President of ETS, said the company is very excited to be working with DSS, supporting opportunities for educational institutions to fly cubesats. The company’s Sleek Eagle launch vehicle mated with the firm’s Cubesat Ring dispenser is capable of launching dozens of cubesats and other satellites on a single mission.

Evelyn Torres Bada, President of DSS, added that the educational market for cubesat missions is significantly underserved. Various STEM and government programs support development of satellites but not flying them and, as a result, there are hundreds of cubesats in colleges and universities around the world that are waiting for an opportunity to fly.

She added that the current high cost of flying cubesats, even as secondary payloads, has prohibited most from launching. The company’s price point is significantly under today’s costs and the firm plans to meet this large and growing need. DSS understands the tremendous educational value and motivation that being part of a satellite program operating in space can be for students at all levels. These un-launched satellites could become a significant boon for STEM related subjects when they are orbiting the Earth.

Amazon Web Services reveals AWS Ground Station services

Amazon Web Services, Inc. (AWS), an Amazon.com company (NASDAQ:AMZN), has announced the general availability of AWS Ground Station, a new service for customers to control satellites from AWS and download data from satellites into AWS Global Infrastructure Regions using a fully managed network of ground station antennas located around the world.

Once customers upload satellite commands and data through AWS Ground Station, they can quickly download large amounts of data over the high-speed AWS Ground Station network, immediately process it in an Amazon Elastic Compute Cloud (Amazon EC2) instance, store it in Amazon Simple Storage Service (Amazon S3), apply AWS analytics and machine learning services to gain insights, and use Amazon’s network to move the data to other regions and processing facilities.

Getting started with AWS Ground Station takes just a few clicks in the AWS Management Console to schedule antenna access time and launch an Amazon EC2 instance to communicate with the satellite. There are no up-front payments or long-term commitments, no ground infrastructure to build or manage and customers pay-by-the-minute for antenna access time used. To get started with AWS Ground Station, visit https://aws.amazon.com/ground-station

Satellites are being used by more and more businesses, universities and governments for a variety of applications, including weather forecasting, surface imaging, and communications. To accomplish this today, customers must build or lease ground antennas to communicate with the satellites. This is a significant undertaking and cost as customers often require antennas in multiple countries to download data when and where they need it without waiting for the satellite to pass over a desired location.

The antennas are just the start of the infrastructure requirements as customers need servers, storage, and networking in close proximity to the antenna to process, store, and transport the data from the satellite. Then customers must build business rules and workflows to organize, structure, and route the data to employees or customers before it can be used to deliver value. This requires significant capital investments and operational costs to build, manage, and securely maintain antennas, compute infrastructure, and business logic at each antenna location.

AWS Ground Station allows customers to more easily and cost-effectively control satellite operations, ingest satellite data, and integrate the data with applications and other cloud services running in AWS.

Using AWS Ground Station, customers can save as much as 80 percent of their ground station costs by paying for antenna access time on demand and they can rely on AWS Ground Station’s growing global footprint of ground stations to downlink data when and where they need it.

These ground stations are also located in close proximity to AWS Regions around the world, so customers can store, process, and analyze the data locally, rapidly gain insights, and then quickly take action.

The recency of data is particularly critical when it comes to tracking and acting upon fast-moving conditions on the ground. This timeliness depends on frequent communications between ground stations and satellites, which can only be achieved with a large, global footprint of antennas maintaining frequent contact with orbiting satellites.

For example, as fast-moving environmental, geopolitical, or news events unfold on the ground, AWS Ground Station customers can downlink current data to any of the AWS ground stations around the world. Customers can get timely data sooner, rapidly experiment with new applications, and deliver products to market faster without buying, leasing, or maintaining complex and expensive antennas and infrastructure. AWS Ground Station’s self-service graphical interface makes it easy to identify downlink opportunities, communications windows, and schedule antenna time. This enables customers to review confirmed times in the console and cancel or reschedule prior to the scheduled contact time.

Because AWS Ground Station antennas are located in close proximity to AWS Regions, customers have low-latency, local access to additional AWS services to process and store data. For example, they can use Amazon EC2 to control satellites and downlink data, store and share the data in Amazon Elastic Block Store (Amazon EBS), Amazon Elastic File System (Amazon EFS), or Amazon S3, use Amazon Virtual Private Cloud (Amazon VPC) for secure communications between Amazon EC2 instances and the AWS Ground Station antenna gateway, hunt for real-time business insights with Amazon Kinesis Data Streams and Amazon Elastic Map Reduce, apply machine learning algorithms and models with Amazon SageMaker, add image analysis with Amazon Rekognition, and improve data sets by combining satellite data with IoT sensor data from AWS IoT Greengrass.  AWS Ground Station is available immediately in U.S. East (Ohio) and U.S. West (Oregon) and will expand to additional regions and locations in the coming year.

Shayn Hawthorne, GM, AWS Ground Station, said the goal of AWS Ground Station is to make space communications ubiquitous and to make ground stations simple and easy to use, so that more organizations can derive insights from satellite data to help improve life on earth and embark on deeper exploration and discovery in space.


Rohde & Schwarz has revealed their latest satellite uplink amplifier

For the first time in the U.S., Rohde & Schwarz presented their R&S® PKU100 Ku-band satellite uplink amplifier in an outdoor version at a recent satellite show.

This uplink amplifier combines the best of two worlds in a single device: the unbeatable strengths of solid-state amplifiers and the compactness and low weight of tube amplifiers.

This weatherproof model is perfectly suited for outdoor applications and features all of the advantages of the indoor model.

The R&S PKU100 can be used in ground stations and satellite news gathering (SNG) vehicles.

Four models of the R&S PKU100 will be available, each in an indoor and an outdoor version.

The R&S PKU100 is obtainable for the 12.75 GHz to 13.25 GHz and 13.75 GHz to 14.5 GHz bands, with RF peak powers of 400 W and 750 W.

The solid-state power amplifier is just as light, compact and energy-efficient as conventional tube amplifiers and therefore clearly superior to comparable solid-state products.

The new outdoor models are particularly robust and weatherproof and comply with IP65 ingress protection specifications, plus they offer numerous features required for outdoor applications.

The R&S PKU100 can be mounted very close to the transmit antenna, saving RF power and minimizing capital and operating expenses.

Same as with the indoor model, the fans can be hot swapped in the event of a failure.

If fitted with an optional redundant power supply, the R&S PKU100 will continue operating should one of the power supplies fail.

The R&S PKU100 uses solid-state output stages throughout and offers a genuine alternative to conventional tube technology.

Should individual transistors fail, for example, the amplifier will continue operating at reduced power.

The R&S PKU100 is the only instrument on the market to offer adaptive linearization.

This improves signal quality, enabling network operators to transmit significantly more data over the same signal bandwidth. The amplifier offers excellent efficiency, reducing operating costs.

The R&S PKU100 can be fitted with a block upconverter (BUC), allowing low-frequency L-band signals to be processed and converted to the Ku-band.

The amplifier can be controlled remotely; it supports all common standards such as a web interface, SNMP, RS 232 and parallel I/O interfaces.
