The trials, consisting Newtec’s modems and Telesat’s LEO satellite, achieved zero packet loss when tested on the Ka-band payload, said the companies
Newtec has announced that its modems have been successfully tested over-the-air on Telesat’s inaugural Low Earth Orbit (LEO) satellite. The trials, which were conducted on Telesat’s Phase 1 LEO satellite operating on the Ka-band payload, saw test user traffic successfully passed over the satellite via Newtec’s modems, and achieved operations without packet loss, said the companies.
Frederik Simoens, CTO at Newtec, explained: “The testing process began with small-scale tests and we have been working our way up throughout the process, with these latest tests showing the potential of LEOs in efficiently and reliably delivering end-user traffic.
“Our modem portfolio, combined with next-generation on-board technologies, is ideally suited to bring maximum efficiency and throughput.”
Newtec’s modems were installed for the project at Telesat’s Allan Park facility. Telesat expects to conduct live phase 1 LEO testing with its customers in the coming weeks. Telesat’s LEO constellation is aimed to deliver a combination of capacity, speed, security, resiliency, latency and low cost, delivering affordable fibre-quality connectivity everywhere. Once fully deployed, Telesat LEO will accelerate 4G/5G expansion, bridge the digital divide with fibre-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.
Dave Wendling, CTO of Telesat, added: “Telesat is pleased to collaborate with vendors like 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 fibre-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.”
