The elements of the network concept are defined in the list below. This network will be composed of the following elements:

  • A set of software clients for spacecraft operators to command remotely the satellites. From now on, they will be defined as Mission Operations Clients or M-Clients for short.
  • A set of software clients for providing direct access to the services of the ground station facilities. From now on, Ground Station Clients or G-Clients for short.
  • A cloud system for the coordination of the communications in between these two types of clients. From now on, Network Communications System or N-System. It is important to note that the N-System is not a single server but a cloud-computing-based system. This way and depending on further implementation decisions, this cloud system may evolve into a network of interconnected servers that will provide the service required.

For providing these services, the N-System implements the following interfaces:

  • G-Client Interface (G-Client-IF), that permits the ground station clients to connect to the network services.
  • M-Client Interface (M-Client-IF), that permits the mission operations clients to connect to the network services.

The following diagram provides a graphical definition of the elements of the network and how they are interconnected with the given interfaces.

Network Concept

Authentication, security and communications privacy is implemented by using a secure transport layer for ensuring that a private communications link is established in between G- and M- clients. The registration process of the clients in the cloud N-System is the first step for the secure distribution of keys and certificates along the clients of this network.
