  • Publication number: 20220052754
    Abstract: Methods and systems for low earth orbit satellite communications, utilizing fractionated satellites and constellations with large baselines. The latter, combined with spatial multiplexing protocols, provides access to user equipment on the ground with much greater spatial resolution than hitherto possible. Methods include overcoming the problem posed by the round-trip delay of satellite links when adaptive, downlink, beamforming is attempted in Frequency Division Duplex (FDD) systems. Methods include using of uplink and downlink pilot signals which eliminate the need for controlling the physical integrity of the fractionated satellite through an electromechanical servo-control system in space.

  • Publication number: 20210358188
    Abstract: In various examples, a virtually animated and interactive agent may be rendered for visual and audible communication with one or more users with an application. For example, a conversational artificial intelligence (AI) assistant may be rendered and displayed for visual communication in addition to audible communication with end-users. As such, the AI assistant may leverage the visual domain—in addition to the audible domain—to more clearly communicate with users, including interacting with a virtual environment in which the AI assistant is rendered. Similarly, the AI assistant may leverage audio, video, and/or text inputs from a user to determine a request, mood, gesture, and/or posture of a user for more accurately responding to and interacting with the user.

  • Publication number: 20210273703
    Abstract: Systems and methods for adaptive beamforming for a mobile satellite system (MSS). Embodiments described herein provide individual-user-optimized, adaptive beamforming. One example system creates a user beam optimized based either on known user locations or the waveforms received from all cochannel users. The user beam maximizes the signal-to-interference-noise relative to the desired user, both in the forward and return links. The optimization process considers the spatial distribution of all cochannel users in the footprint of the satellite. The user beam adapts to the user's location and co-channel interference environment.
