ASECNA In Conjunction With NIGCOMSAT And Thales Alenia Space Provides The First African Early SBAS Open Service

Published

on

The Agency for Air Navigation Safety in Africa and Madagascar, ASECNA, has started to broadcast an SBAS (Satellite-Based Augmentation System) signal over Africa & Indian Ocean (AFI) region, providing the first SBAS open service in this part of the world via NIGCOMSAT-1R Satellite managed and operated by Nigerian Communications Satellite Ltd under Federal Ministry of Communications and Digital Economy of Nigeria.

This early open service is provided as part of the « SBAS for Africa & Indian Ocean » program which pursues the autonomous provision over the continent of SBAS services, to augment the performances of the satellite navigation constellations GPS and Galileo. With improved accuracy to within a meter, and boosted integrity, availability, and continuity of safety-related applications, these SBAS services will improve flight safety and efficiency in Africa, and also benefit to the economy in many areas as land, sea, and rail transport, as well as mass-market applications, supporting user safety, cost-effectiveness and sustainable development.

The launched open service essentially aims to carry-out technical trials, and to undertake with partner airlines field demonstrations for aircraft and rotorcraft, to demonstrate the benefits of the future operational safety-of-life SBAS services, expected from 2024. It will also include early Precise Point Positioning (PPP) and emergency warning service to populations, which performance will be proven through other demonstrations.

The signal-in-space is generated by a dedicated system testbed, developed as part of the “SBAS for Africa and the Indian Ocean” preliminary design phase, financed by the European Union and awarded to Thales Alenia Space, a Joint Venture between Thales (67%) and Leonardo (33%). The “SBAS for Africa and Indian Ocean” is based on the European EGNOS [1] developed by the European Space Agency (ESA) acting under the delegation of the European Commission and operated by the European GNSS Agency GSA.

The system prototype uses as reference stations network the SAGAIE network deployed by CNES and ASECNA with the support of Thales Alenia Space.

The signal is broadcasted via the SBAS payload on the NigComSat 1R GEO satellite of the Nigerian Communications Satellite Ltd and an uplink station deployed in Abuja (Nigeria). It is compliant with the Standards and Recommended Practices of the International Civil Aviation Organisation, and the Minimum Operational Performance Standard developed by the RTCA (Radio Technical Commission for Aeronautics) organization. It will be visible in the whole Africa and the Indian Ocean, up to the West Australian coast, and also in Europe.

“We are proud to be part of this ambitious program to provide satellite navigation services in the Africa and Indian Ocean region. The use of our geostationary communication satellite NIGCOMSAT-1R navigation payload to broadcast the first signal will be Africa’s premier contribution to SBAS as a regional satellite-based augmentation system for the continent” declared Dr. Abimbola Alale, MD/CEO of NIGCOMSAT Ltd.

“Our longstanding expertise acquired with the development of EGNOS1 SBAS in Europe and KASS SBAS in Korea combined with our new leading-edge satellite positioning technologies makes Thales Alenia Space the ideal partner to best support countries to implement their own SBAS efficiently. The equatorial region represents also a key engineering challenge for such a system due to difficult ionosphere conditions, for which Thales Alenia Space has developed a proven solution”, declared Benoit Broudy, Vice President of the Navigation business at Thales Alenia Space in France.

“The provision of the first African SBAS early service is a crucial major step forward in the development of satellite navigation in the AFI Region, and in the deployment of the “SBAS for Africa and the Indian Ocean” system, the navigation solution for Africa by Africa. It demonstrates the ambition and commitment of ASECNA to enhance air navigation safety for the benefit of the whole continent, in line with my vision for the unification of the African Sky”, stated Mohamed Moussa, Director General of ASECNA.

Ismaila Sarr: Manchester United And Liverpool Enter Battle For Watford Star’s Signature

Published

on

Manchester United’s hopes of signing their number one transfer target Jadon Sancho before the transfer window closes on October 5 are diminishing by the day.

Dortmund has made it clear to United that they won’t budge on their eye-watering £108 million asking price.

Man Utd wants to sign the England international, 20 but isn’t prepared to pay a transfer fee that they deem to be excessive.

Unless either club backs down, Sancho will remain a Dortmund player until January at the earliest.

With just over two weeks to go before the window closes, United are now considering other potential options.

And towards the top of their list of alternatives is Watford’s, Ismaila Sarr.

The Senegal international impressed last season, despite the fact Watford were relegated to the Championship.

The Independent understands that United would need to fork out at least £30 million to sign the 22-year-old, who joined the Hornets from Rennes in a deal worth roughly the same amount in August 2019.

Watford’s relegation has weakened their hand and Sarr is the club’s most valuable asset.

However, in the news that will no doubt concern the United hierarchy, Liverpool also want Watford’s No. 23.

This is according to The Daily Mail, who claim the Reds have enquired about the winger and discussed his situation with Watford.

Sarr, the Mail add, is being seriously considered as a back-up option for Liverpool’s front three.

The report also says that Watford would want at least £36 million for the attacker, who scored six goals and provided six assists in 30 appearances in all competitions last term.

Two of those goals were scored against Liverpool in February when Watford recorded a shock 3-0 victory over Jurgen Klopp’s side.

But The Independent say that Liverpool’s budget is constrained, particularly after agreeing a deal to sign Thiago Alcantara from Bayern Munich.

This, in turn, may put United in the driving seat for Sarr’s signature.

Liverpool ‘Interested’ In Diego Jota

Published

on

Liverpool is reportedly interested in signing Wolves forward Diogo Jota. Jota’s absence from Wolves’ Carabao Cup defeat against Stoke on Thursday was shrouded in mystery.

The 23-year-old reportedly turned up at Molineux but left before the match started.

Jota was an unused substitute in Wolves’ 2-0 opening day Premier League win over Sheffield United on Monday.

And now Liverpool is said to be keen on the Portuguese star, according to The Times’ Paul Joyce.

After the 1-0 loss to Stoke, Wolves manager Nuno Espirito Santo was coy on what happened to Jota.

“He was not available for the game,” Nuno said.

“We have a short squad and all the options are good, but he and Max Kilman were not available for this game.

“He wasn’t available, these are decisions we have to make. We have to prepare the squad, have to know what is the moment of the season.

“It was a big turnaround, we have to take care of the players, improve our squad and our team and he was not available for the game. These are our decisions to make.

“I was watching the game. He was not on the squad list.

“There was no confusion. When a player is not on the squad list sometimes they see the match, if they are away, they stay at home.

“It’s because we have a bubble, we have to make a list, all those details. Nothing strange.”

Jota has been one of Wolves’ star players since their promotion back to the Premier League.

He initially joined the club on loan from Atletico Madrid in 2017, where he scored 17 goals to help them gain promotion out of the Championship.

Wolves made the deal permanent in 2018 and he has scored 16 goals in 67 Premier League appearances.

Russian Billionaire Mikhail Prokhorov Denies Man Utd Takeover Bid

Published

on

Russian billionaire Mikhail Prokhorov has denied reports that he will be making an attempt to purchase Manchester United from the Glazer family, according to Daily Mail.

Reports of takeovers of Manchester United are becoming a regular occurrence but former Brooklyn Nets owner Mikhail Prokhorov has responded to rumors linking him with a takeover bid of Manchester United.

Prokhorov, who sold his remaining shares of Brooklyn Nets after initially being a sole owner, is reportedly looking to get involved in the sports industry again.

According to reports to the Daily Mail, however, the reports are said to be false: “Prokhorov, who invested heavily into the Nets before selling his share, is an individual who does have the wealth to fund such a deal but, for now, it seems he does not have any interest in a return to sports ownership,” the publication said.

Source have told the Daily Mail that Prokhorov, who has a valued net worth of over £8 billion by Forbes, has ‘no immediate plans’ to make a return to the sporting scene.

Manchester United fans will be glad to see the back of the Glazer family if that day comes but it won’t be Prokhorov who takes the club off their hands – for now.
