摘要:A two-way satellite communications system includes an Earth station

communicating with a plurality of remote terminals using a network access protocol thatfacilitates low power consumption by the terminals. The earth station generates forwardlink TDM packet data transmissions on one or-more satellite channels, and detects,despreads and decodes multiple concurrent return link slotted CDMA packettransmissions on one or more satellite channels. It communicates through a wiredconnection with a packet processing center which ultimately both delivers return linkpacket data to end-customers and receives forward link packet data from end-customers. The remote terminals receive, process and act upon forward link TDMtransmissions on one or more satellite channels, and generate slotted spread spectrumCDMA transmissions on the return link on one or more satellite channels. The remoteterminals communicate with a local digital data source and/or sink, digitize one or morelocal analog sensor signals, enter into a sleep mode to minimize the terminal's powerconsumption, and access the satellite communications network in accordance with the

system network access protocol.
