Low Earth Orbit satellites, improving latency

What is LEO?

Low Earth Orbit satellites circle the earth at a distance of about 1000km, your typical satellites are either Geostationary Earth Orbit (GEO) satellites located at a distance of 36,000km or your mid range satellites MEO located at about 8,000km. Being closer to the earth has its benefits as the latency delay will drop, that is the time it takes for your data to complete a round trip (RTT), going from earth to satellite and back again. The GEO latency is of 600 milliseconds, MEO of 180ms and LEO of 40ms, the new LEO satellite “Constellation” will allow you to access noticeably faster response times that are important for various applications such as Internet browsing, messenger or online chats, Voice over IP (VoIP), gaming, and an essential part if you are conducting High Frequency Trading (HFT).

LEO Satellite Constellation

Who will provide this?

In 2022 our partner Telesat will begin deployment of their “Lightspeed broadband constellation” with the launch of 298 LEO satellites. This network of satellites will create an orbiting communication mesh that covers the entire globe. Telesat plan to offer guaranteed speeds of up to 7.5 Gbps to single terminals as well as polar-orbit coverage . Lightspeed will allow us to provide our customers with the most extensive, lowest latency and fastest available VSAT global coverage.

How does it work?

Rather than having to follow one geostationary satellite, yachts will be able to follow various satellite beams simultaneously. These satellites will be significantly closer to earth, reducing the latency of the signal, and their capacity to link between provides redundancy to guarantee the service.

What are the advantages of the LEO constellation?

• High Throughput
• Low Latency 30-50ms
• Lower costs
• Complete global coverage
• Higher look angle
• Flexible and focused Capacity where required
• Less interference
• Inter Satellite links offer optimal routing

What should I, as a client, take into consideration?

Existing Antennas may need to be replaced or updated, but here the specifications are not clear yet and these replacement could be timed in-line with service expectancy.

At Omniaccess we are already looking into flexible solutions for our clients to make the transition as smooth as possible. In any case, we expect the return on switching to LEO to massively outweigh the possible investments required and will provide periodic updates for our clients as soon as further details are made available.
