Army, NASA Want Laser Micro-Satellites For 50 Times The Bandwidth

By

It was hard enough keeping the data flowing to the far mountains of Afghanistan, but at least the Taliban didn't have the technology to attack the network. Russia and China, however, are investing heavily in capabilities to eavesdrop on or jam the radio transmissions and to blind or outright shoot down the satellites.

ASSOCIATION OF THE US ARMY, ARLINGTON: War zones, it turns out, get crappy reception. But the Army, NASA, and multiple private companies are looking to optical communications — that means lasers — off affordable micro-satellites that could dramatically increase bandwidth. Just this morning, the federally funded Aerospace Corporation announced a successful test for NASA that provided bandwidth 50 times higher — an almost 5,000 percent increase — than current military satellites that use radio waves.

Bassett: Military Necessity

Not three hours before the Aerospace Co. announcement, Maj. Gen. David Bassettwas getting excited about optical satellites at the Association of the US Army's annual cyber and networks conference here. That matters because, after a successful tour in charge of armored vehicle programs, Bassett is now the Army's Program Executive Officer for Command, Control, Communications – Tactical (PEO-C3T).

Currently, Bassett said, during a typical exercise at the Joint Readiness Training Center, meant to depict realistic combat conditions, an Army brigade HQ gets a satellite link that can transmit two megabits a second. By comparison, he said, one of his fellow panelists, Forcepoint Federal CTO George Kamis, had just clocked his smartphone at 70megabits per second. That's 35 times the power the 4,000-soldier brigade gets, for just one person.

“We have to provide more bandwidth to a headquarters than Mr. Kamis has in his pocket,” said Bassett.

    L'UE attribue son 1er contrat de recherche sur la défense

    FRANCFORT, 19 février (Reuters) - Un consortium dirigé par Rheinmetall a remporté le premier contrat relatif à la recherche sur la défense de l‘Union européenne (UE), a annoncé lundi le groupe allemand de défense. Le consortium va mener des études en vue d‘une éventuelle standardisation des systèmes de défense à l‘échelle de l‘UE, regroupant l‘électronique, les communications vocales, les logiciels et les capteurs, a-t-il ajouté. Les autres membres du consortium sont les groupes espagnols Indra et GMV Aerospace and Defence, les italiens Leonardo et Larimart, l‘Organisation néerlandaise de recherche scientifique appliquée TNO, l‘entreprise polonaise iTTi, la société portugaise Tekever ASDS et le suédois SAAB . La recherche-développement sur la défense financée par l‘Union européenne est censée redonner de l‘élan à la coopération dans ce domaine primordial et prouver aux Etats-Unis et à Donald Trump que l‘Europe entend bien financer sa propre sécurité.

    L3Harris looks to shed as much as 10 percent of company

    By: Jill Aitoro WASHINGTON — L3Harris Technologies could divest up to 10 percent of the company, according to CEO Bill Brown, as its recent decision to sell its airport security business for $1 billion is seen as the first of more transactions expected to refine the firm's portfolio. L3Harris signed a definitive agreement to sell the business unit to Leidos, according to an announcement Tuesday. The transaction is expected to close in mid-2020, barring any issues tied to regulatory approvals. Proceeds from the divestiture are expected to be used to repurchase shares and offset dilution. The deal is part of a larger strategy to reshape the portfolio, focusing on what Brown described on a call with analysts as “high-margin, high-growth, technology-differentiated businesses where we can win and generate attractive returns.” “Although this is the first and largest transaction we're contemplating, our portfolio-shaping process is ongoing and may ultimately result in 8-10 percent of total company revenue being divested over time,” he said. The company's 2019 revenue of $18.1 billion could translate to as much as $1.8 billion in divestitures. Brown told Defense News in June 2019 — one month before the merger of Harris and L3 Technologies was completed — about plans to divest a “pretty significant” piece of the business in the first six months as a single company. “Anytime you put two companies with two portfolios together and you rethink what strategy you want to accomplish, there's going to be some pieces of the portfolio at the back end of the bus,” Brown said at the time. “We have to look at where we want to put our management time, capital, and [research and development] investment. We can't put it on pieces that might not be as strategic." Brown told analysts that the deal would not impact the company's $3 billion free cash flow target in 2022. That in theory would set up L3Harris for a sizable acquisition down the road, should the company choose to go in that direction. A company spokesman could not comment on the specific defense-nondefense split post divestiture, but L3Harris would presumably see a larger slice of the business focusing on defense opportunities. In the 2019 Defense News Top 100 list of the largest defense companies, Harris and L3 reported 72 percent and 81 percent of revenue as defense-focused, respectively. L3Harris reported $18.1 billion in fiscal 2019 revenue. Once the deal with Leidos closes, the airport security businesses' $500 million in annual revenue would transition off the books. That said, L3Harris is forecasting 5-7 percent revenue growth in 2020 — so it won't be a straight reduction. https://www.defensenews.com/industry/2020/02/04/l3harris-looks-to-shed-as-much-as-10-percent-of-company
