Hybrid orbits

Satellites in an industry-first combination of polar and inclined orbits, resulting in complete global coverage, including polar areas, with higher capacity where most of the world’s population lives

Benefits

Telesat LEO delivers unsurpassed performance at transformative economics

Aeronautical, Maritime, Enterprise, Telecom and Government networks can rely on these unique benefits:

Copper colored icon representing high throughput

High Throughput

Gigabits per second speeds to a remote, and multiple Tbps of capacity in the network ensures enterprise-grade connectivity anywhere in the world.

Copper colored icon representing low latency

Low Latency

The Telesat LEO Network is about 20-times more responsive than today’s geosynchronous satellites and on par with fiber networks.

Copper colored icon representing scalability

Flexible & Focused

Our intelligent network can dynamically allocate bandwidth to areas with high traffic demand such as large communities or airport hubs.

Copper colored icon representing always on

Always On

Highly resilient, secure network with multiple inter-connected satellites and ground nodes without any single point of failure ensures networks always stay connected.

Copper colored icon representing low cost

Affordable

Telesat LEO technology is more cost-effective for ubiquitous reach than fiber and microwave alternatives. Our disruptive pricing empowers customers to expand their coverage and propel their growth.

Quick Service Deployment

Compliant with Metro Ethernet Forum (MEF) standards for seamless plug-and-play integration.

Terminals

Cost-effective user terminals for every application

Telesat is testing and working with leading manufacturers to ensure that cost-effective, high-performing customer terminals are available to access the Telesat LEO network. Telesat LEO will fully support both electronically steered antennas (ESAs) and mechanically steered antennas for commercial, government, and defence markets including requirements for land, land-mobile, aeronautical, maritime, and other platforms. 

Telesat LEO terminals will be easy to deploy, will self acquire the satellite network and will provide Gbps capacity with Metro Ethernet Forum (MEF) compliant interfaces for seamless integration to the terrestrial network.

Demonstrations

Telesat’s first Low Earth Orbit (LEO) satellite was launched in January, 2018 and is now supporting live demonstrations across a variety of markets and applications. Live demonstrations allow Telesat customers and LEO hardware vendors test low-latency, high throughput performance, satellite tracking and Doppler compensation.
