Shape satellite communications research with MDA Space and Safran Trusted 4D through SAPPHIRE’s integrated PNT architecture.
ÉTS seeks a postdoctoral fellow for a full time, four-year position in downtown Montreal, starting as soon as possible. Within LASSENA and the SAPPHIRE partnership, you will develop PNT capabilities for MDA Space’s Aurora LEO constellation. The research integrates broadband DVB-S2X, Direct-to-Device links, and 5G/6G Non-Terrestrial Networks. Work includes constellation simulators, SDR platforms, hardware-in-the-loop testing, and validation toward TRL 5. The role also addresses GNSS-free navigation, passive radar, and spectrum anomaly detection for emergency-management scenarios.
Key Responsibilities: Design communication waveforms and frames embedding synchronization markers
Develop multi-source positioning and timing estimation algorithms




Contribute to hybrid multi-protocol SDR receiver design
Define QoS frameworks for latency, accuracy, continuity, and integrity
Guide TRL transitions and coordinate partner technical reviews
Requirements: Recent Ph.D. in electrical, telecommunications, aerospace, or related engineering
Expertise in at least two specified PNT or communications areas
Experience with USRP, GNU Radio, or comparable SDR platforms
Programming skills in Python, MATLAB/Simulink, C, or C++
Publication record and scientific collaboration experience
Bring satellite communications, SDR validation, waveform design, and PNT expertise to ÉTS’s collaborative SAPPHIRE project.
