    摘要: The disclosed technology relates to systems and methods for tasking satellite constellations. A method is disclosed herein for receiving, from a resource database of a satellite control system, knowledge data corresponding to a plurality of components associated with a satellite constellation communications system. The plurality of components can include one or more satellites associated with a constellation. The method includes processing the knowledge data according at least one received mission objective. Processing the knowledge data can include determining a status of at least one satellite in the constellation. The method includes scheduling the satellite control system based at least in part on the received mission objective and the processed knowledge data; initiating communication with the at least one satellite in the constellation according to the scheduling; receiving updated status information for at least one component of the plurality of components; and storing, in the resource database, the updated status information.

    摘要: Certain implementations of the disclosed technology may include systems and methods for reducing noise in dual-frequency GNSS signal observation. The method can include: receiving, at a GNSS receiver, a first signal and a second signal. At least the second signal includes noise. The first signal is characterized by a first carrier frequency, and the second signal is characterized by a second carrier frequency. The method includes: down converting, sampling, cross-correlating, accumulating, determining ambiguous instantaneous phases, determining non-ambiguous instantaneous phases, producing normalized non-ambiguous instantaneous first phase samples, constructing a normalized first counter rotation phasor, generating a counter-rotated second observable, applying a low pass filter to remove noise; and outputting the filtered second observable.
