Vehicular navigation based on site specific sensor quality data

A method for determining a location of a vehicle, the method comprising:

• determining reception location data within a first cell of a work area for a vehicle;
• estimating reception quality data for the corresponding reception location data for the first cell;
• determining optical location data within a first cell of a work area for a vehicle;
• estimating optical quality data for the corresponding optical location data for the first cell;
• determining dead-reckoning location data within a first cell of a work area for a vehicle;
• estimating dead-reckoning quality data for the corresponding dead-reckoning location data for the first cell;
• and
• selecting at least one of the reception location data, the optical location data, and dead-reckoning location data as refined location data associated with the first cell based on the estimated reception quality data, estimated optical quality data, and estimated dead-reckoning quality data.

A system for determining a location of a vehicle, the system comprising:

• a location-determining receiver for determining reception location data within a first cell of a work area for a vehicle;
• a reception quality estimator for estimating reception quality data for the corresponding reception location data for the first cell;
• an optical location-determining receiver for determining optical location data within a first cell of a work area for a vehicle;
• an optical quality estimator for estimating optical quality data for the corresponding optical location data for the first cell;
• and
• a data processor for selecting at least one of the reception location data and the optical location data as refined location data associated with the first cell based on the estimated reception quality data and estimated optical quality data.
