Building on their previously announced agreement, the two companies have successfully demonstrated key capabilities of Farcast’s electronically steered antenna (ESA) technology through an extensive development and test program. The work validates Farcast’s innovative architecture, which reduces hardware complexity without compromising performance and significantly lowers size, weight, power, and cost (SWaP-C).

The program culminated in an over-the-air demonstration using Telesat’s LEO 3 test satellite. Farcast successfully established and maintained end-to-end satellite connectivity through its shared-aperture user terminal, with measured performance closely matching predicted link budgets. The results provide strong validation of the underlying terminal technology. This milestone paves the way for the next phase of the collaboration: the development of a fully integrated user terminal for the Telesat Lightspeed network, bringing together Farcast’s antenna platform and the Telesat Lightspeed modem solution.
