  • Method and system for providing satellite correction signal with warm start
    Patent number: 11150352
    Abstract: In one embodiment during a warm-start mode, an estimator estimates a satellite correction signal based on satellite orbit data, satellite clock data, and satellite bias correction data derived from stored received raw satellite signal measurements. A data source selector seamlessly switches a measurement data source from the stored received raw satellite signal measurements to live, real-time raw satellite signal measurements if or when a respective measurement time tag of a last-processed one of the stored received satellite signal measurements approaches or reaches the current time.
    Type: Grant
    Filed: June 25, 2018
    Date of Patent: October 19, 2021
    Assignee: DEERE & COMPANY
    Inventors: Sonia U. Kuntz, Nirav R. Parikh, Junkun Wan, Liwen L. Dai

  • Precise low-latency GNSS satellite clock estimation
    Patent number: 10191157
    Abstract: A wide-lane ambiguity and a respective satellite wide-lane bias are determined for the collected phase measurements for each satellite for assistance in narrow-lane ambiguity resolution. Satellite correction data is determined for each satellite in an orbit solution based on the collected raw phase and code measurements and determined orbital narrow-lane ambiguity and respective orbital satellite narrow-lane bias. A slow satellite clock correction is determined based on the satellite orbital correction data, the collected raw phase and code measurements, and clock narrow-lane ambiguity and respective satellite narrow-lane bias.
