Abstract
In one instance, disclosed herein is a method for providing a GNSS future coverage map, the method comprising: receiving worksite geography data associated with a worksite and satellite ephemeris data associated with a future time period; determining, based at least in part on the worksite geography data and the satellite ephemeris data associated with the future time period, GNSS coverage of the worksite throughout the future time period; generating a future coverage map representing the GNSS coverage of the worksite throughout the future time period; and causing a graphical user interface (GUI) to display the future coverage map.
Claims20
A method for providing a global navigation satellite system (GNSS) future coverage map, the method comprising:
- receiving worksite geography data associated with a worksite and satellite ephemeris data associated with a future time period;
- determining, based at least in part on the worksite geography data and the satellite ephemeris data associated with the future time period, GNSS coverage of the worksite throughout the future time period;
- determining an elevation offset associated with the worksite;
- adjusting the determined GNSS coverage of the worksite throughout the future time period by applying the determined elevation offset to the determined GNSS coverage;
- generating elevation-adjusted GNSS coverage of the worksite throughout the future time period based on the application of the determined elevation offset to the determined GNSS coverage;
- generating a future coverage map representing the elevation-adjusted GNSS coverage of the worksite throughout the future time period;
- and
- causing a graphical user interface (GUI) to display the future coverage map.
A method for providing a global navigation satellite system (GNSS) future coverage map, the method comprising:
- receiving worksite geography data associated with a worksite and satellite ephemeris data associated with a future time period;
- determining, based at least in part on the worksite geography data and the satellite ephemeris data associated with the future time period, GNSS coverage of the worksite throughout the future time period;
- receiving satellite ephemeris data associated with a historical time period;
- determining, based at least in part on ground-truth GNSS data associated with the worksite and the satellite ephemeris data associated with the historical time period, an elevation offset associated with the worksite;
- generating, based at least in part on the GNSS coverage of the worksite throughout the future time period and the elevation offset associated with the worksite, a future coverage map representing the GNSS coverage of the worksite throughout the future time period;
- and
- causing a graphical user interface (GUI) to display the future coverage map.
A system for providing a global navigation satellite system (GNSS) future coverage map, the system comprising at least one processor operative to:
- receive worksite geography data associated with a worksite and satellite ephemeris data associated with a future time period;
- determine, based at least in part on the worksite geography data and the satellite ephemeris data associated with the future time period, GNSS coverage of the worksite throughout the future time period;
- determine an elevation offset associated with the worksite;
- adjust the determined GNSS coverage of the worksite throughout the future time period by applying the determined elevation offset to the determined GNSS coverage;
- generate elevation-adjusted GNSS coverage of the worksite throughout the future time period based on the application of the determined elevation offset to the determined GNSS coverage;
- generate a future coverage map representing the GNSS coverage of the worksite throughout the future time period;
- and
- cause a graphical user interface (GUI) to display the future coverage map.
