  • Satellite beam power backoff
    Patent number: 9538538
    Abstract: A method and apparatus for a non-geosynchronous orbit (NGSO) satellite to comply with equivalent power flux density (EPFD) limits are disclosed. The example implementations may allow a constellation of NGSO satellites to comply with EPFD limits without disabling beams transmitted from the NGSO satellites. The power level of one or more beams to be transmitted from the NGSO satellites may be dynamically adjusted according to a beam power back-off schedule. In some aspects, the beam power back-off schedule may specify beam power back-off values as a function of latitude on Earth, and may allow for maximum allowable power levels for beams transmitted from the NGSO satellites without violating any of the EPFD percentile limits.
    Type: Grant

    Date of Patent: January 3, 2017
    Assignee: QUALCOMM Incorporated
