A mobile satellite system includes a network engineeringsystems engineering system. Identification numbers of the components are read and then verified. There are also at least four collectors delimited, inside the metal casing of the heat exchanger by two axial-end cupels or outer cupels that are arranged transversely and close the axial ends of the metal casing of the heat exchanger. A movable joint movably connects the first and second sections of the tool support for movement between an operative position and a compact position, in which the first and second sections are oriented such that the tool support is substantially more compact in the compact position than in the operative position.
