Telesat LEO Phase 1 satellite: Launched 2018

SSTL supplied a small low earth orbit (LEO) satellite to Telesat, a leading global satellite operator, as part of a test and validation phase for an advanced, global LEO satellite constellation.

The satellite flies an SSTL-built Ka payload and utilises hydrazine propulsion systems for in-orbit raising and de-orbiting.  It is operated by Telesat in low earth orbit at ~1000km

In 2019 Telesat LEO Phase 1 satellite demonstrated the first ever 5G connectivity on a LEO spacecraft.
