‘Fibre in the sky’ makes 10 000 laser connections

Published

on

The SpaceDataHighway system – the world’s first ‘optical fibre in the sky’ based on cutting-edge laser technology – has achieved 10,000 successful laser connections. The reliability rate has reached 99.8 percent, and during the first one and a half years of routine operations these successful connections have downloaded more than 500 terabytes of data.

The system’s satellites are designed to lock on to low-orbiting satellites via laser and collect their data as they travel in low Earth orbit scanning the Earth. From its position in geostationary orbit, the SpaceDataHighway acts as a relay, transmitting the large quantities of data acquired by these observation satellites down to Earth in near-real time at a speed of 1.8 Gbit/s, instead of storing the data on board until the satellites pass over their own ground station.

The establishment of the laser connections is controlled by the SpaceDataHighway’s Mission Operation Centre which operates 24 hours a day, seven days a week at Airbus premises near Munich. Operators receive transmission requests from customers, programme the space and ground segment and monitor the performance of communications.

“While 2017 has been a year of ramp-up for the system, we have now reached more than 1,000 connections per month in 2018 with a very high level of reliability,” said 

Hughes Boulnois, Head of the SpaceDataHighway programme at Airbus Defence and Space. “The total amount of data transferred is equivalent to around 100 million MP3 music files, but the transmission capacity of the SpaceDataHighway goes far beyond that.”

Each day, the SpaceDataHighway is capable to relay up to 40 terabytes of data acquired by observation satellites, Unmanned Aerial Vehicles or aircraft, to Earth. It is currently used by the European Union’s Copernicus programme, but its capacities could be used by many more customers.

In 2019, the system will also relay information from the Columbus module of the International Space Station (ISS). From 2020 the Pleiades Neo satellites will begin to use the SpaceDataHighway.

The SpaceDataHighway is a public-private partnership between the European Space Agency and Airbus, which today owns and operates the system, with the laser communication terminals developed by Tesat-Spacecom and the DLR German Space Administration. EDRS-A, the first SpaceDataHighway relay satellite launched in 2016, offers coverage from the American East Coast to India. A second satellite, EDRS-C, will be launched in 2019. It will double the system’s capacity and extend the coverage and redundancy of the system. Airbus intends to expand the SpaceDataHighway with a third node, ERDS-D, to be positioned over the Asia-Pacific region.

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entires via Twitter, so please don’t enter through the comments section of this article.)

2. Tell us on Twitter, via @GadgetZA, mentioning @Takealot in your posting, how many Watts the Poster Heater consumes.

cleardot.gif3. The competition closes on 31 July 2018.

4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.

5. The competition is only open to South African residents.

Deezer to host Hotstix’s Mandela tribute playlist

Deezer is celebrating Nelson Mandela on the centenary of his birthday by hosting a tribute playlist created by music legend Sipho “Hotstix” Mabuse.

Mabuse, a legendary figure in African music, first rose to prominence in the 1970s with his band Harari and later developed a name for himself as a solo artist. One of his best known songs was the global hit BurnOut in the 1980s.

The playlist takes the listener on a captivating musical journey through the life of Nelson Mandela.  It was compiled by Mabuse, who consulted with Mandela’s family and friends to ensure that the music would be relevant and accurate. The playlist also features commentary by Mabuse, which was recorded in his Soweto home.  

“I have tried to tell the story of the music that Madiba loved,” says Mabuse. “The Playlist excludes the time in prison obviously, as Madiba would not have had exposure to music in that time.  We have focused on the music we know he loved before and after that period. This recording was really an emotional journey for me, but an incredible opportunity to document these memories.”

The playlist features the music the young Mandela loved, such as The Manhattan Brothers, Solomon Linda, Brenda Fassie and Miriam Makeba.  It includes struggle songs from Chicco, Johnny Clegg, Hugh Masekela and Yvonne Chaka Chaka.  The playlist also includes Mandela by Zahara, one of the younger artists who caught Madiba’s ear.

Mabuse also offers stories of his own songs, such as Shikisha, a song greatly beloved by the former President.

“I was delighted to share my thoughts and hope the listeners enjoyed the musical journey,” says Mabuse. “Madiba did enjoy music immensely and we all have a purpose wherever we are in the world to celebrate culture and to learn from different cultures and music forms and styles.”

This playlist was inspired by the Nelson Mandela 100 campaign, calling on corporates and individuals to act as sources of inspiration and engage in conversation and action.
