A satellite communications system provides an information channel between
remotely located transmitters and receivers. A virtual satellite system
provides the same service, but divides the signal either in power or in
data content into subchannels such that any particular signal is
conducted to the intended receiver via a plurality of traditional
satellite channels. The receiving terminal accepts the plurality of
signals simultaneously from a possible plurality of satellites, combining
the subchannels comprising the virtual channel into the original signal
content as if conducted via a single channel. The receiving antenna
system receives satellite subchannel signals from a plurality of
directions using multiple antennas or a single antenna with
multi-direction capability. Prior to signal combining, the receiver
necessarily time-synchronizes the plurality of subchannels by introducing
time delay in some channels before combining the subsignals into the
original composite. A timing signal present in the virtual satellite
system assists the receiver in determining the amount of delay to apply
to each incoming signal. The timing signal is either a separate carrier
or an additional modulation on the existing information-bearing carrier.
