Abstract
A system includes a transmitter configured to emit a signal. The system includes a control system, configured to determine a geographical mitigation region of a satellite, determine the transmitter is located within the geographical mitigation region, and modify an operation of the transmitter to mitigate interference with an observation sensing activity of the satellite.
Claims12
A system, comprising:
- a server computer, including:
- a database storing satellite path data for a plurality of satellites, and
- a processor configured to:
- retrieve a first satellite path data for a first satellite from the database;
- calculate, using the first satellite path data, a geographical mitigation region path, the geographical mitigation region path defining a plurality of geographic mitigation regions and observation time periods during which at least a portion of each geographical mitigation region of the plurality of geographic mitigation regions will be observed by the first satellite;
- and
- transmit, using a wireless communication network, the geographical mitigation region path to a plurality of vehicles that are within a geographical region;
- and
- a vehicle, including:
- a global navigation satellite subsystem,
- a vehicle radar subsystem configured to transmit radar signals according to a predetermined duty cycle that defines an off period in which the vehicle radar subsystem does not transmit the radar signals and an on period in which the vehicle radar subsystem does transmit the radar signals, and
- a control system configured to:
- receive, using the wireless communication network, the geographical mitigation region path;
- determine a location of the vehicle using the global navigation satellite subsystem;
- determine that the location of the vehicle is within a geographical mitigation region of the plurality of geographic mitigation regions;
- determine an observation time period associated with the geographical mitigation region;
- and
- modify a duty cycle of the vehicle radar subsystem to align the off period of the duty cycle with the observation time period so that the observation time period occurs during the off period to mitigate interference with an observation activity of the first satellite.
