Telesat Tech Stack

Global satellite operator building low-earth-orbit network for telecom and government

Telecommunications Ottawa, Ontario 501–1,000 employees Founded 1969 Public Company

Telesat operates a multi-decade satellite infrastructure business and is executing a major constellation shift with Lightspeed, its low-earth-orbit (LEO) network designed for telecom, government, maritime, and aeronautical customers. The tech stack—heavy on satellite standards (DVB-S2X, DVB-RCS2, TDMA), operations platforms (Netcracker, Amdocs, Ericsson), and data pipelines (Databricks, Spark, Kafka)—reflects a mature, mission-critical operation managing both legacy GEO assets and new LEO infrastructure. Engineering dominance in hiring (41 of 78 open roles) paired with active projects spanning constellation commissioning, system verification, and operational training underscores the scale of this multi-year transition.
