General outline

General outline

This session will provide our attendees with an overall summary of the various specific characteristics of the space environment and related constraints (module 1), along with the engineering concepts required to understand the technical fundamentals of a space mission (module 2).

Based on these background elements, our attendees will go through each component that make up a satellite communications system (module 3) and a satellite Earth observation system (module 4).



Module 1: Space environment and associated constraints

Vincent ASTIER, Senior Consultant, Satellite & Launcher Expert, Satconsult  

Space environment
  • Key space environment characteristics
  • Orbital mechanics
Space constraints
  • Launch constraints
  • Effects of orbital perturbations on spacecraft
  • Effects of the space environment on materials and electrical components
Implications for spacecraft design
  • On-board thermal regulation
  • Electronic hardening
  • Orbit determination and control
  • Mechanical testing


Module 2: General introduction to space missions

Jérôme COLINAS , Senior Consultant, Satcom and Earth Observation Expert, Satconsult  

Key mission components
  • Space segment architecture: platform and payload
  • Ground and launch segment
  • Mission operations
Key applications and system design
  • Types of missions and objectives

Module 4: Satellite Earth observation systems overview

Jérôme COLINAS , Senior Consultant, Satcom and Earth Observation Expert, Satconsult 

  • Environment (meteorology, agriculture, forestry, etc.)
  • Intelligence (economic, security, defense)
Main parameters and drivers
  • Main characteristics of the observation targets (size, frequency of occurrence, wavelength of observability)
  • Design drivers (revisit, resolution, wavelength, day/night, all-weather, local, global, tasking cycle)
  • Going from requirements to launch and operations
System architecture
  • Space segment (number of satellites, orbits, agility, …)
  • Ground segment (stations, ISL, processing, dissemination)
  • ‘Optical, radar (imagery, altimetry), lidar
  • Connected systems: Geoint, Sigint
