According to Northern Sky Research (NSR), wholesale operator revenue from non-geostationary constellations, such as Telesat Low Earth Orbit (LEO), is expected to post a compound annual growth rate of more than 40% during the next decade. The benefits of non-geostationary satellites include very high-throughput, service reliability, cost-effectiveness, low latency and overall superior broadband performance.

​​Milestone Moment

Telesat is just one operator currently investigating this new technology and its Phase 1 LEO satellite was launched on January 12, 2018. The company is now conducting live demonstrations of its capabilities – an important milestone in Telesat’s plans to deploy a global LEO constellation that will revolutionize broadband communications around the world.

Telesat’s testing of the Ka-band payload is ongoing and Newtec’s modems are the first to have been successfully tested over-the-air on Telesat’s inaugural LEO satellite, with the technology demonstrating different service scenarios. The latest trials saw test user traffic successfully passed over the satellite via Newtec modems, showing that flawless operation without packet loss can be achieved on LEO constellations.

Newtec’s modems were installed for the project at Telesat’s Allan Park facility last September and shortly after that Telesat conducted live phase 1 LEO testing with its customers. Telesat’s unique LEO constellation will combine the company’s global spectrum rights in Ka-band with Telesat’s proprietary LEO architecture to transform global communications. The constellation is designed to deliver an unsurpassed combination of capacity, speed, security, resiliency, latency and low cost, delivering affordable fiber-quality connectivity everywhere.

Once fully deployed, Telesat LEO will accelerate 4G/5G expansion, bridge the digital divide with fiber-like high-speed services into rural and remote communities, and set new levels of performance for commercial and government broadband on land, sea and in the air.

Maximum Efficiency and Throughput

A rapidly growing technology with huge potential, LEO is one trend we are watching closely at Newtec and we are pleased that our modems were able to support Telesat on this important technology proof. The testing process began with small-scale tests and we worked our way up throughout the process, with the latest tests showing the potential of LEOs in efficiently and reliably delivering end-user traffic. Our modem portfolio, combined with next-generation onboard technologies, is ideally suited to bring maximum efficiency and throughput.

“Telesat is pleased to collaborate with high technology vendors such as Newtec to validate key performance aspects of our LEO system design. Our state-of-the-art LEO constellation will combine Telesat’s global spectrum rights in Ka-band with our proprietary LEO architecture to provide fiber-like broadband performance where terrestrial networks cannot reach. This latest round of testing marks a significant step towards the future, showing that advanced modem technology, which works seamlessly with LEO satellites, is already available on the market today.”
