Drifting on an Arctic Ice Sheet for a Year Scientists Use Kepler’s World’s First High-Bandwidth Satellite

Don’t know if any penguins were involved in the successful experiment that Kepler Communications demonstrated delivering over 100Mbps connectivity service in the Arctic region to the German icebreaker Polarstern.

The vessel is located around 85 degrees N and is the home to the MOSAiC scientific expedition. The demonstration marks the first time in history that the central Arctic is successfully connected through a high-bandwidth satellite network. 

Kepler’s two polar-orbiting satellites are being used to transfer data for scientists taking part in MOSAiC, the most extensive research expedition ever to the North Pole. MOSAiC is an international expedition consisting of hundreds of scientists and operations crew, which will remain locked into the Arctic ice sheet to study the environment. The team will spend the next 12 months drifting along with the ice sheet, with the purpose of the mission being to take the closest look ever at the effects of climate change on the Arctic. 

Kepler has provided the Polarstern is equipped witthe world’s only high-bandwidth satellite data link delivered from low-Earth orbit (LEO) that is available in the Arctic. With the vessel operating well outside the range of traditional high-throughput satellites, Kepler is providing 100x higher data speeds, when the satellite passes the vessel than would be otherwise available to the ship. This improved data transfer capability means scientists can share large data files between ship and shore, improving the ability to share, analyze, and disseminate information.

Mina Mitry, CEO at Kepler said that their Global Data Service provides a cost-effective means to transfer large data volumes that will be gathered over the course of MOSAiC. Rather than only storing data locally and analyzing once physical storage can be sent back with supply vessels, they are giving scientists the ability to continuously transfer test and housekeeping data sets over their unique LEO satellite network. 

Kepler’s Global Data Service™ will save time, money and, most importantly, improve the ability for MOSAiC scientists to carry out their critical mission of studying climate change.

In charge of MOSAiC’s logistics is the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI), from Germany. They are responsible for leading this international expedition that involves the joint efforts of 19 countries around the world. With over USD 158 million in funding, the most advanced technology on a research icebreaker, and an astonishing quantity of planning and logistics, MOSAiC is the largest expedition to the North Pole ever in history.

Professor Markus Rex, MOSAiC project leader and atmospheric scientist at the Alfred Wegener Institute in Potsdam added that the high polar regions are the last frontiers of the globe where high bandwidth data connections could not be established so far. Kepler’s new Global Data Service now enables them to send back bulk data, including key data files for monitoring the status of instruments together with experts at home. This will contribute to the success of MOSAiC.

The MOSAiC expedition began when the Polarstern set sail from Norway this past September and will continue for more than a year. Findings from the mission will help better assess the future of Earth’s climate, and provide valuable information to help fight climate change. 

Kepler is the world’s only provider of high-bandwidth satellite services in the poles. Aboard the Polarstern, Kepler has demonstrated data rates of 38 Mbps downlink and 120 Mbps uplink to a 2.4m Ku-band VSAT (Very Small Aperture Terminal). 

 

SSTL Ships Target Satellite to Tokyo for Astroscale’s ELSA-d Mission

Surrey Satellite Technology Ltd. (SSTL) has shipped a 16 kg. Target satellite for Astroscale’s End-of-Life Services by Astroscale demonstration (ELSA-d) mission to Tokyo, where it will be bolted to the Chaser satellite for environmental testing ahead of the launch in 2020.

The ELSA-d mission is designed to simulate capture of orbital debris and validate key technologies for end-of-life spacecraft retrieval and disposal services. The Target and Chaser satellites will be attached for launch and de-orbit, but while on-orbit at 500 to 600 km., they will be deployed in a series of increasingly complex separation and capture maneuvers using search, identification, rendezvous, docking, and de-orbit technologies.


The ELSA-d mission comprises of a Chaser satellite and the Target satellite, and will demonstrate key technologies for orbital debris removal.

The ELSA-d Target satellite was designed and manufactured by SSTL in Guildford, UK, and incorporates S-band communications, GPS positioning, and a 3-axis control system. It will also fly an HD camera and lighting to record the capture sequences during eclipse. A ferromagnetic docking plate with optical markers is attached to the Target, allowing the ~180 kg. Chaser satellite to identify and estimate attitude before deploying a capture extension mechanism with a magnetic plate to latch on to the Target satellite.

While rendezvous has been performed on-orbit in the past, ELSA-d will demonstrate the first semi-autonomous capture of a non-responsive, tumbling Target, as well as the first identification of a Target that is outside of the field of view of the relative navigation sensors on the Chaser. Once the demonstration concludes, the linked satellites will be moved to a lower orbit in readiness to re-enter the atmosphere where they will burn up.

NovaSAR-1 was designed and manufactured at SSTL, with an S-band payload developed by Airbus Defence and Space in Portsmouth, UK, and an Automatic Identification Receiver supplied by Honeywell Aerospace. The SAR payload has a dedicated maritime mode designed with a very wide swath area of 400km to enable the monitoring of the marine environment and will provide direct radar ship detection information simultaneously with AIS ship tracking data to assist with the identification and tracking of sea-going vessels.  

Mission partners already under contract for NovaSAR-1 data include the UK Space Agency, Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Indian Space Research Organisation (ISRO). 

NovaSAR-1 is owned and operated by SSTL.

Andrew Cawthorne, Director of Earth Observation at SSTL, said the company is delighted to welcome DOST-ASTI colleagues to the NovaSAR-1 data team. SSTL anticipates that the Philippines will benefit greatly from NovaSAR-1 data, particularly as the country has a tropical climate with frequent cloud cover, and an extensive coastline and maritime territory.

Dr. Joel Marciano, Jr., Acting Director of DOST-ASTI, added the SAR imaging capability of NovaSAR-1 is a timely and powerful resource as the institute continues to push scientific data, computing and space technology in support of evidence-based politics and decision-making in the country.

Mr. Alvin Retamar, Chief Science Research Specialist at DOST-ASTI, commented that NovaSAR-1’s simultaneous acquisition of SAR and Automatic Identification System (AIS) data targets enhanced maritime domain awareness that is expected to lead to more effective interventions.

Hiber’s Smallsat IoT Network is Now Live

Following the launch of its first smallsats into the stratosphere in late 2018, Dutch startup Hiber has announced that the firm’s Internet of Things (IoT) network is now live.

After only three years of product development, the commercial launch of the fully automated end-to-end service known as Hiberband, marks the latest step for Hiber, where it will see its first customers trialing the technology.

Hiber’s first customers will be trialing the service over the coming months with projects based in the 90% of the world that have previously lacked a network. Hiber is unlocking a $100 billion opportunity for growth in the wider IoT market and the network will power projects working hard to improve people’s lives and make a positive impact on the environment. 


Artistic rendition of a Hiber smallsat on-orbit.

Existing terrestrial networks (such as Lora, NB-IoT or GSM) only work in urban areas, while traditional satellites that provide wider coverage are expensive and power hungry. Hiberband is disrupting global connectivity by empowering individuals and organisations to reliably transmit data (text message size) from the world’s most hard-to-reach places for less than a dollar per month per device with its state of the art end-to-end service. 

With more than 70 customers already signed up, projects on every continent will benefit from Hiberband. Any industry operating in remote and developing areas can use the network, with early adopters being from government, environment, transport & logistics, agriculture and mining. A sample of some of the first uses cases to trial the network include:

– Soil Moisture Monitoring – Monitoring soil moisture levels on farms helps farmers understand whether their crops need water. The sensors developed by Hiber partner Royal Eijkelkamp ensure that farmers make the right irrigation decisions, reducing water waste and increasing crop yields. Hiberband makes this solution globally available.

– Beehive Monitoring – Bees have been facing the threat of extinction for more than fifteen years, and Hiberband’s technology will be instrumental in ensuring successful cultivation and preservation of bee colonies. Bee farmers can monitor the environment inside hives anywhere on the globe using sensors connected via Hiberband, ensuring that the conditions are optimal for bee survival and honey production.

– Crop Monitoring / Post Harvest – Monitoring crops will help farmers across the world reduce food waste and spoiled crops. Centaur Analytics has developed an “Internet-of-Crops™” platform that monitors the condition of harvests all the way from the farm to the consumer. Hiber enables Centaur to provide customers in the US and globally with updates on crop conditions no matter where they are in the world.

Hiber will introduce two networks, Hiberband Direct (a modem + antenna that talks directly to Hiber’s satellites) and a gateway solution, Hiberband Via, which can operate on LoRa (a network widely used for IoT connectivity), Bluetooth or WiFi. Hiber launched its first two satellites from sites in Sriharikota, India and California, USA in November and December, 2018. It will be launching its third and fourth satellites in Q1 2020 also in Sriharikota, India.

Laurens Groenendijk, Managing Director Commercial and co-founder at Hiber (and co-founder of JustEat and Treatwell) said, “We are extremely proud to announce that after only 3 years of hard work, Hiberband is the first network of its kind to become operational on a global scale. We have the team, partners, technology and regulatory building blocks in place to shortly be the industry leader. With full freedom to operate everywhere in the world, we are looking forward to supporting our customers wherever they need to be.” 

Sotiris Bantas, CEO at Centaur Analytics said, “Earth’s growing population combined with climate change is placing enormous stress on the world’s food supply chain. The lack of transparency in the chain is causing about one third of the crops in the world to be wasted before consumption. Together with Hiber, we are now able to effectively monitor crops after harvest globally – no matter the location. This means that Centaur and Hiber together combat food waste and promote sustainability, while at the same time providing new business opportunities for producers, traders, and CPG companies.”

The ALE Sky Canvas Shooting Star Project Satellite Gets the Spaceflight Treatment for a Rocket Lab Electron Launch

Spaceflight has arranged for Tokyo-based ALE to launch that firm’s entertainment and science satellite on Rocket Lab’s next Electron launch.

The mission, called “Running Out of Fingers” by Rocket Lab to signify the company’s tenth mission, represents Spaceflight’s third launch with Rocket Lab this year and follows the launch of seven spacecraft on Rocket Lab’s inaugural “Make it Rain” mission in June and three on the “Look Ma No Hands” mission in August. 

Similar to the previous missions, Spaceflight managed the launch capacity procurement, integration, and mission management services for the rideshare spacecraft. The Electron, carrying the ALE satellite, will lift-off from Rocket Lab’s Launch Complex 1 at the southern tip of Mahia Peninsula, on the east coast of New Zealand’s North Island. The launch window opens on November 25, NZDT.

ALE’s Sky Canvas, the world’s first man-made shooting star project, will deploy to a 400 km. circular Sun Synchronous Orbit (SSO), which is beneath the International Space Station. The company’s satellite will create man-made shooting stars by safely releasing particles, precisely controlling the reentry location, date, and timing. When the particles re-enter the Earth’s atmosphere, they fully burn up, creating the appearance of shooting stars on the ground. 

In addition to the entertainment factor, the Sky Canvas project will also study the path and mechanics of shooting star particles during re-entry from the upper atmosphere. The data collected in the mesosphere will be helpful in the aerospace industry to help predict the path of satellites and artificial objects as well as contributing to scientific understanding in several technology fields including meteorology and the study of climate change.

Following this launch, Spaceflight will have launched 11 spacecraft on the Electron and has plans to continue partnering with the launch vehicle provider in 2020. Spaceflight has completed five missions already this year, with another five planned in 2019. Other noteworthy missions from the last year include Spaceflight’s GTO-1, which deployed the first commercial lunar lander aboard a SpaceX Falcon 9, and SSO-A, the company’s historic dedicated rideshare mission, successfully launched 64 unique smallsats, making it the single largest deployment of satellites from a U.S.-based launch vehicle.


Curt Blake

Curt Blake, the CEO and President of Spaceflight, said the company’s experience offering end-to-end launch services across multiple launch vehicles continues to be highly valued by organizations — regardless if they’re a newer customer like ALE, or an experienced constellation developer. The firm’s expertise and long-standing relationships provide reliability, flexibility, and the confidence that we’ll get customers to space as efficiently as possible. Spaceflight is really looking forward to taking ALE on this third Electron launch this year.


Lena Okajima

Lena Okajima, the CEO of ALE, added this launch gets the company much closer to realizing the world’s first man-made shooting star. ALE really appreciates Spaceflight`s support and attention to this mission and the company is honored to take this big step with them.

 

 

China Launches Three Chinese Satellites Plus a Sudanese SRSS-1 Smallsat 

On Sunday November 3, China launched a new Earth Observation (EO) satellite, Gaofen-7, which will play an important role in land surveying and mapping, urban and rural construction and statistical investigation, according to the China National Space Administration (CNSA).

The Gaofen-7, launched on a Long March-4B rocket at 11:22 a.m. (Beijing Time) from the Taiyuan Satellite Launch Center in north China’s Shanxi Province, is China’s first, civil-use, optical transmission, three-dimensional surveying and mapping satellite that reaches the sub-meter level, CNSA said.
