Key design elements of the satellite system

Based on the identified need and established constraints, the aim is to design different system solutions that will meet the requirements while respecting the limitations. The elements presented in the previous sections illustrate the need for a systemic approach, as many elements are strongly correlated with each other. This design phase involves major architectural choices.

The design of the satellite telecommunications space segment is directly influenced by the requirements of the ground and user segments. Bandwidth requirements for broadband services determine the choice of frequencies, such as the Ku and Ka bands. The latency required for real-time applications may necessitate the use of low orbits. The design also incorporates security and dynamic reconfiguration features for greater flexibility. Interoperability with terrestrial networks, such as 5G, is...
