Two multi-beam, high-throughput payloads – GX10A & 10B – will operate in Highly Elliptical Orbits (HEO), ensuring continuous coverage and featuring the ability to direct capacity in real-time to the areas of highest demand.

What is the I-4 satellite?

Our award-winning Inmarsat-4 (I-4) fleet of satellites established the world’s first global 3G mobile network. Launched between 2005 and 2008, the first three I-4s were built by an international team from the United Kingdom, France, Germany, the USA and Canada. With each satellite able to generate up to 19 wide beams and more than 200 narrow spot beams, the I-4s introduced always-on, seamless high-speed connectivity to every corner of the world. In 2013 we launched Alphasat to supplement the I-4 fleet, providing coverage over Europe, the Middle East and Africa and bringing new capabilities including 50 per cent more accessible L-band spectrum and nearly 20 per cent more mobile communication channels.

Inmarsat, which currently operates 14 satellites, is also on track to add five new GEO and two HEO spacecraft to its network over the next five years.

Who is the chief technology officer of Inmarsat?

The LEO satellites will expand “the tool kit of things we can offer to them,” Inmarsat chief technology officer Peter Hadinger said in an interview.

Does Inmarsat have spectrum licenses?

Hadinger is confident Inmarsat will be able to obtain regulatory clearances, despite coming late to the LEO arena, pointing to the spectrum licenses it already has in L , Ka, S and other bands .

Who is developing the LEO constellation?

Canadian satellite operator Telesat is also developing a LEO constellation for enterprise and government markets, but has yet to start launches.

New use cases and business models

ORCHESTRA’s unprecedented combination of global coverage, unparalleled capacity and resilience will provide customers with a low-risk transition to next generation service capabilities, enabling new business models and use cases well into the future.

One cohesive solution

ORCHESTRA will integrate Inmarsat’s existing geosynchronous (GEO) networks with terrestrial 5G and a new, targeted LEO satellite deployment.

A cost-efficient, strategic investment

ORCHESTRA reflects a natural evolution of our technology roadmap, leveraging existing market-leading network assets, and supporting a continued strategic focus on global mobility customers.

Why is Orchestra a LEO?

Orchestra is designed to deal with that because it has a terrestrial component based on 5G technology, the LEO component which means we can do lower latency connections, and then it still has the GEOs on top for support. The idea is to make sure we can deliver the right amount of capability and capacity for the given requirement for mobility customers, which means it needs those three legs.

Why is mobility important?

The second one is really important because they often need to just turn up somewhere and get a connection.

How many spacecraft will be in Inmarsat?

The company announced in late July that it will enter the arena to better serve mobility verticals, unveiling plans for at least 150 LEO spacecraft to complement its fleet in geostationary and highly elliptical orbits from 2026. Inmarsat’s plan includes a terrestrial 5G network in high-demand areas to support the multi-orbit network it calls Orchestra.

Why can we do some things for you?

Increasingly we’re having these conversations with them about, well, maybe we can do some things for you because we’re going to get to that faster than you are.

Why are there screens on the forearm?

In the military, you’re seeing small rectangular screens on a person’s forearm so they can get live updates directly to the person, and share them with each other. They can also get further updates from the vehicle or get a direct feed from a UAV. All of those things are now required to be joined up, so that’s the reason why we need to be able to deliver more bandwidth, and to something that is much smaller and easier to carry for a person.

When will Inmarsat be used?

The Australian Defence Force recently extended a contract to use Inmarsat’s satellites to 2027. Does that agreement cater to Orchestra’s arrival?

How Inmarsat Satellite Coverage Works?

The satellites are positioned to transmit radio beams in two global configurations covering the oceans and major land masses. It is important to note that Inmarsat coverage extends from latitudes of -82° to 82° regardless of longitude, so higher latitudes like the polar regions are not covered.

How to receive calls on Inmarsat?

To receive a call on your Inmarsat phone number, the antenna of your device needs to be pointed toward the equator to register and connect with the Inmarsat network. To maintain your network connection with the Inmarsat satellites over the equator, the device should remain in a stationary position while you are expecting a call or on a call. TIP: Roadpost’s Isatphone monthly plans and prepaid cards include voicemail service, in case you miss a call.

How many satellites does Inmarsat use?

The Inmarsat network uses three (3) geostationary satellites to provide voice and data communications almost everywhere on earth.

Why does it take so long to register a satellite?

Registration to the network requires a clear line of sight to the equator and may not be suitable for use in canyons or mountains. Because the satellite orbit further from earth , network registration times may take a little longer than with competing networks.

What is Inmarsat satellite?

Inmarsat has stood at the forefront of mobile satellite services for 30 years. As internationally recognised as pioneers in the field, they continue to introduce new technologies that redefine the standard for our industry. Their new Broadband Global Area Network (BGAN) service, for example, is now enabling TV broadcasters to beam breaking news ‘live via videophone’ into millions of homes. And in future, when you make a mobile phone call or send a text message from an aircraft, most likely it will be transmitted via Inmarsat satellites to the ground.
