Tasks summary

Architecture Concept & Requirements

• Define TT&C/PDT functional architecture (command generation, uplink, telemetry downlink, on-board data handling, RF front-end).
• Conduct trade-studies for modulation schemes, coding, frequency plans, ranging and link budgets.
• Produce System Requirements, Interface Control (ICDs), and Description documents.
• Perform requirement management and maintain bidirectional traceability throughout the project lifecycle.
• Collaborate with cyber-security to embed resilience and security by design.

Design & Development

• Lead detailed design of hardware (TT&C transceiver, RF front-ends, antenna-pointing) and software (command sequencer, telemetry parser, health-monitoring).
