Telesat selects Space Flight Laboratory to manufacture LEO 3 demonstration satellite
OTTAWA and TORONTO — Telesat announced a contract award to Space Flight Laboratory (SFL) of Toronto, Ontario to manufacture a Low Earth Orbit (LEO) demonstration satellite for Telesat.
The demonstration satellite, named LEO 3, will provide continuity for customer and ecosystem vendor testing campaigns following the decommissioning of Telesat’s Phase 1 LEO satellite. Once successfully launched and on-station, LEO 3 will operate under an existing ITU network filing for Telesat Lightspeed, the company’s enterprise-class LEO constellation.
“We’re excited to partner with SFL, who has as a proven track record for building high-performing satellite platforms – on time and within budget,” stated Dave Wendling, Telesat’s Chief Technical Officer. “LEO 3 will serve an important role for low-latency customer applications testing, and for supporting LEO antenna and modem development efforts in advance of our Telesat Lightspeed satellite deployment.”
SFL is developing LEO 3 on its popular DEFIANT microsatellite platform. The completed LEO 3 will be a compact microsatellite measuring 30x30x45 cm with a mass of 30 kg. More than a dozen DEFIANT satellites developed for SFL clients are now in orbit serving applications ranging from maritime ship tracking to radio frequency signal mapping.
“DEFIANT is a scalable platform with the power capabilities and versatility to support a variety of mission objectives, yet it is compact enough to keep launch costs at a manageable level for commercial programs,” said SFL Director Dr. Robert E. Zee. “SFL is pleased that our microspace technology can be the enabler for Telesat to achieve its demonstration goals for high bandwidth operations in LEO.”
LEO 3 is nearing completion at SFL following a relatively aggressive development schedule. SFL has integrated the communications payload with the LEO 3 bus and successfully completed vibration and electromagnetic compatibility testing of the spacecraft. Additional tests are ongoing.
