EM Solutions Successfully Completes In-Orbit Tests of Telesat LEO 3 Satellite Transponder

EM Solutions has successfully completed the first of its system-level tests for a transponder developed for Telesat’s LEO 3 demonstration satellite. Launched on 18 July, the satellite payload features a flexible bent pipe architecture featuring both Ka-band and V-band uplinks and downlinking on either Ka or Q-band.

Its compact size, weight, and power consumption were tailored for operation on Space Flight Laboratory’s (SFL) DEFIANT platform, a compact microsatellite measuring just 30x30x45 cm and weighing only 30 kg.

Expanding on EM Solutions’ experience with space flight hardware, the communications payload was designed and manufactured at the company’s Brisbane, Australia head office. The facility now includes a new ISO7 (Class 10000) clean room, encompassing 100 square meters, new workstation areas, and wire bonding machines. 

With a primary focus on SATCOM terminals operating at X-band and Ka-band, EM Solutions has over the years demonstrated its agility in leveraging broad microwave experience to produce bespoke products for a range of applications.

Garth Niethe, Chief Engineer at EM Solutions, reflected on the collaboration stating, “This was a great collective effort by EM Solutions’ design, test, and assembly members and the company’s suppliers and customers, SFL and Telesat. The effort was even more significant given the tight schedule and global component shortage issues. We specifically want to thank the National Space Test Facility at the Australian National University for their support in undertaking environmental testing.”

He further added, “We want to continue to leverage the successful research and development efforts in Q and V bands for our most recent satellite transponder payload as we venture into other applications utilizing our substantial expertise in microwave product design and manufacturing.”
