摘要

A spacecraft, having a satellite receiver, that is configured so that the direction of the downlink beams transmitted from the satellite receiver depends on the location of the uplink signals transmitted from the ground and not the attitude of the spacecraft in space.

1. A spacecraft comprising:
a satellite receiver having receive elements, the satellite receiver being configured to receive at least one uplink communication signal including a beam amplitude and a beam frequency; a satellite amplifier configured to change the beam frequency and to amplify the beam amplitude; and a satellite transmitter having transmit elements, the satellite transmitter being configured to transmit at least one downlink communication signal; wherein a direction of the at least one uplink communication signal and a direction of the at least one downlink communication signal are independent of an attitude orientation of the spacecraft relative to Earth.
