Patent number: 10771145Abstract: A satellite communication system processes a plurality of input signals to generate beamformed signals, drives a plurality of nonlinear power amplifiers with the beamformed input signals to produce RF signals for transmission; and transmits the RF signals with a plurality of Tx antenna elements. Conversion to and from linear signals to and from nonlinear or digitized signals is performed. Temporal or spatial decorrelation of the beamformed signals is employed to reduce the impact of intermodulation products. In some cases the power amplifiers are nonlinear, and can be one-sided or two-sided and produce two or three distinct output levels.Type: GrantFiled: March 10, 2017Date of Patent: September 8, 2020Assignee: SEAKR ENGINEERING, INC.Inventor: Erik Buehler

Patent number: 10461753Abstract: Systems and methods for synchronizing the clocks of a central device and one or more destination devices are disclosed. In some embodiments the central device and destination devices are implemented in a space-based or high-altitude asset. The central device provides a series of synchronization pulses to the one or more destination devices. In response to detecting, at the destination device, the synchronization pulse, a sample of the destination device clock is stored in a register. The sample is provided to the central device. The sequence is repeated at least once. A phase offset between the central device clock and the destination device clock may be determined based on the returned samples and the position of the samples within the register.Type: GrantFiled: May 11, 2018Date of Patent: October 29, 2019Assignee: SEAKR ENGINEERING, INC.Inventors: Jeff Pritchard, Jeff Highley, James Randolph, III

Patent number: 9900072Abstract: 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.Type: GrantFiled: June 9, 2016Date of Patent: February 20, 2018Assignee: SEAKR ENGINEERING, INC.Inventor: Damon Van Buren

Patent number: 9612900Abstract: 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 experienced an upset.
