Abstract: Systems, devices, and methods for satellite communications are disclosed. The devices and methods can be used for communications diversity in a system having multiple radio frequency terminals (RFTs). In a transmit chain, each RFT can be associated with an antenna for the transmission of signals to a satellite. The system can select one or more uplinks for transmission of one or more versions of a transmit signal via associated antennas. The one or more versions can have a piggyback signal associated with and phase locked to a symbol rate of the transmit signal. In a receive chain, phase differences between the piggyback signals can allow adjustment of one or more time delays in the transmit chain to provide improved signal to noise ratio of the received versions of the transmit signal in the receive chain.
