Abstract
The APOLLO electronic document delivery system general requirements (encryption, monitoring, data communication protocols, interfaces) and satellite communication system requirements (information rate, channel quality, traffic unit, number of simultaneously active ground stations, satellite access time, data message structure, size and retransmission) are outlined. System elements, the satellite network, protocol-dependent message exchanges, and data-station interface requirements are described. The maintenance alarm concept is introduced.
