Correction D'un Oral !

[Invité]

Bonjour,

Je viens d'apprendre par surprise que je passe en oral d'anglais ( rattrapage ) demain matin ...

Je suis militaire, actuellement en école pour une montée en grade ...

Je vous propose donc mon sujet d'oral, assez bref au final 3 / 4 minutes max puis un entretien oral sur ma vie de marin, mes expériences.

Le sujet dois parler des communications militaires dans la Marine Nationale !!

Je cherche aussi activement quelqu'un pour me poser quelques questions bien coriaces pour vérifier si j'ai le vocabulaire pour y répondre.

D'avance merci pour votre aide.

I'm going to deal with the new way the navy will use UHF or HF communication.

UHF and HF have both been discovered in the early 1920s and have been used during the second world war.

Basically both these transceivers have evolved. They followed the same path of computer innovation. Vacuum tube have been overridden by semi-conductors also overridden by microchip and as a result microprocessors were born.

They have become more reliable, sensitive and a little more powerful. Some rules have been created like Radio check procedure to activate a channel and the international phonetic alphabet is the perfect tool to ensure readability of all kinds of transmission.

HF devices also need skilled radioman to allow a perfect link establishment. It was really hard to fight against ionospheric issues and background noises.

In spite of this major problem, HF and UHF are still the backbone of Navy communication. However new technologies and research are going to improve these mediums.

These two huge improvements are ALE and ARQ. They are only new ways to use UHF or HF mediums.

First ALE, automatic link establishment protocol was created to quickly link many warships using a list of preset frequencies. The right parameters will be selected in accordance with atmospheric conditions and background noises. Speed will also be chosen to ensure a strong connection between the contributor. This method has largely replaced HF prediction charts.

Next ARQ, automatic response requesting protocol taken in charge to transmit as soon as possible all the data to their destination and ensure the integrity of information.

Finally when the network is set up, it can support not only data like Emails or pictures, but also secured voice transmission.

This is the state of the art for a navy task force at sea which want to share tactical data easily.

As you know, we need to perfectly master all kinds of operational data exchange to master the battlefield.
