Satellites Telemetry, Tracking & Command (TT&C)
This training course will enable attendees to understand the operating principles, techniques and space-ground architectures of command & control systems of satellites.
Training course duration: 5 days (30 hours) including:
- 24 hours for presentations
- 3 hours for practical work
- 1 visit of TT&C tracking stations (CNES Aussaguel).
This training course aims at providing the theoretical and practical basic knowledge necessary to understand Telemetry, Tracking & Command (TT&C) systems for satellites:
- The emphasis is on system aspects, starting from user/mission needs and technical/regulation constraints, down to concrete application examples.
Level: Proficiency
Level: Proficiency course
Engineer/MSc diploma or equivalent with basic knowledge in signal processing and transmission (as acquired for example through MTS011 training course: signal processing).
