Abstract: Systems, methods, and non-transitory media are provided for low latency handovers. An example method can include receiving, by a satellite, a schedule of communications between the satellite and one or more gateways; requesting, based on the schedule, a handover from a link between the satellite and a gateway to a different link between the satellite and the gateway or a different gateway; prior to a completion of the handover, processing packets bicasted over the link between the satellite and the gateway and the different link between the satellite and the gateway or the different gateway; performing the handover from the link between the satellite and the gateway to the different link between the satellite and the gateway or the different gateway; and after the handover, transmitting, by the satellite, one or more packets via the different link between the satellite and the gateway or the different gateway.

Abstract: In an embodiment, an apparatus includes a first baseband section to receive a calibration signal; a first radio frequency (RF) section configured to generate a RF calibration signal based on modulating the calibration signal. The calibration signal comprises an orthogonal code based signal. The apparatus includes a second RF section to receive the RF calibration signal and generate a received calibration signal based on demodulating the RF calibration signal; a calibration section; a first antenna electrically coupled to the first RF section and configured to transmit the RF calibration signal; and a second antenna electrically coupled to the second RF section and configured to receive the RF calibration signal. The calibration section is configured to determine one or more of gain, baseband delay, or RF delay to calibrate the first RF section; and the second antenna is switchable between receiving the RF calibration signal and transmitting an encoded data signal.
