Abstract: The present disclosure is directed to a system and method for measuring small frequency differences between two signals quickly and with high precision. In particular examples, an offset between two clock signals on a satellite can be accurately determined in a time period enabling rapid clock synchronization useful in position, navigation, and tracking (PNT) and satellite communications applications. The system and method may also be implemented in constellation of cooperative satellites or other space-borne and high-altitude assets, wherein a plurality of such assets are accurately time-synchronized and more accurate ensemble average calculations are enabled using two-way time transfer (TWTT) protocols. A particular application presently disclosed measurement and correction of very small frequency differences between an atomic clock signal and a tunable clock signal.

Abstract: An integrated analog to digital converting and digital to analog converting (ADDA) RF transceiver for satellite applications, configured to replace conventional analog RF down and up conversion circuitry. The ADDA RF transceiver includes one of more ADCs, DSPs, and DACs, all on a single ASIC. Further, the circuitry is to be radiation tolerant for high availability and reliability in the ionizing radiation environment present in the space environment.

Abstract: An integrated analog to digital converting and digital to analog converting (ADDA) RF transceiver for satellite applications capable of flexibly processing high-bandwidth and low-bandwidth RF input signal(s). The RF transceiver may selectively distribute high-bandwidth RF input signals among one or more DSP pipelines for parallel processing of the RF input signals, and the RF transceiver may coherently recombine the processed signals from the one or more DSP pipelines to generate an RF output signal. The ADDA RF transceiver includes one or more ADCs, DSPs, and DACs, all on one or more ASICs, FPGAs, or modular electronic devices in a single semiconductor package. Further, the RF transceiver is radiation tolerant at the module, circuit, and/or system level for high availability and reliability in the ionizing radiation environment present in the space environment.

Abstract: A hybrid system of satellite-based beamforming that includes digitally beamforming in one axis and physically beamforming in an orthogonal axis. Based on the orientation of the satellite, the digital beamforming axis may be the in-track axis, the cross-track axis, or anywhere in between those two axes. In the digitally beamformed axis, the beam pattern can be steered to different positions along the axis and it can be compressed or expanded, as desired.

Abstract: Methods, systems, and devices for configuration and upset recovery of reconfigurable devices are provided. A central program/recovery manager (CPRM) is coupled with each of a number of reconfigurable devices. The reconfigurable devices are programmed/configured by the CPRM, which then periodically monitors each of the reconfigurable devices to detect if one or more of the devices has experiences an upset. In the event of an upset, the CPRM may attempt to reset the reconfigurable device, scrub a memory of the reconfigurable device, or reprogram the reconfigurable device. A memory module is coupled with the CPRM and each of the reconfigurable devices that stores bit or programming files that may be used to program and/or reprogram the reconfigurable devices.
