Trajectory prediction
First Claim
1. A method for predicting movement of a vehicle in an airspace from a first location to a second location, comprising:
- receiving at least one data signal indicative of a plurality of sensor-perceived first locations of the vehicle;
time correlating the plurality of sensor-perceived first locations of the vehicle; and
particle-filtering the plurality of sensor-perceived first locations to generate a plurality of confidences each corresponding with one of a plurality of predicted locations, each confidence representing a likelihood that the corresponding predicted location includes the second location.

Abstract
Methods and systems for improved prediction of the movement of vehicles through an airspace are disclosed. In one embodiment, a method for predicting movement of a vehicle in an airspace from a first location to a second location, the predicting based upon at least one data signal configured to communicate a plurality of sensor-perceived first locations of the vehicle includes time correlating the plurality of sensor perceived first locations. The plurality of sensor-perceived first locations are particle filtered to generate a plurality of confidences each corresponding with one of a plurality of predicted locations, each confidence representing a likelihood that the corresponding predicted location includes the second location.

17. A method of constructing a path for movement of a vehicle in the presence of at least one hazard in an airspace from a first location to a second location, comprising:
-
monitoring an airspace with sensors configured to perceive a location of the vehicle in the airspace;
generating a data signal according the location perceived by the sensors;
filtering the data signal according to a particle filter algorithm to yield a location confidence function; and
truncating the possible locations according to the location confidence function and a threshold value to yield a location cloud. - View Dependent Claims (18, 19, 20, 21, 22)
